Automatic Plant Watering System using Arduino
Hello friends, I hope you all are doing great. In today's tutorial, we are going to design a Proteus Simulation for Automatic Plant Watering System using Arduino. We have designed this project for engineering students as it's a common semester project, especially in electrical, electronics and mechatronics engineering.
The two most significant hazards to the agriculture industry are the need for extensive labor and a scarcity of water. According to the World Wildlife Fund (WWF) organization, water shortages might affect two-thirds of the world's population by 2025, putting both the ecosystem and human health at risk. The use of automatic plant watering systems eliminates both of these problems by watering plants at specified times and amounts while monitoring their hydration levels through measuring moisture in the soil surrounding the plants. Automatic plant watering systems can be used in homemade gardens and can also be deployed in fields for large-scale use. Whenever designing an automatic watering system, it is important to keep in mind that the system should be expandable, allowing for the simple integration of new devices in order to broaden the applicability of the system.
Software to Install
We are not designing this project using real components, instead, we are going to design its Proteus simulation. So, first of all, you should
Install Proteus Software itself. Proteus software has a big database of electronics components but it doesn't have modules in it. So, we need to install Proteus Libraries of a few components, so that we could simulate them. So, these are the PRoteus libraries which you should install first, before working on this project:
You can download this complete project i.e. Proteus Simulation & Arduino Code, by clicking the below button:

Note:
You should also have a look at these other Proteus Libraries:
Project Overview:
Three main components of an autonomous watering system are:
- Water Level Sensor: monitors the water reservoir level.
- Moisture Sensor: monitors the soil moisture level.
- RTC module: responsible for supplying water to the plant at predetermined intervals or at a predetermined time.
- Arduino UNO: serves as a hub for connecting and controlling all these components.
It is necessary to integrate the water level sensor with the microcontroller before it can be installed within the water reservoir. The location of the water level sensor within the reservoir is variable and is determined by the user and the application for which it is being utilized. The Arduino receives continuous data from the water level sensor and warns the user when the water goes below a certain level, either by an alarm or a buzzer, as appropriate.
The soil moisture sensor operates in a manner similar to that of the water level sensor. The tip of the sensor is inserted into the soil near the plant, and the sensor is activated. In the case of a moisture sensor, the closeness of the sensor to the plant is also variable, and the user may adjust it depending on the features of the plant for which it is being used. In vast agricultural fields, a single sensor may be used for numerous plants if they are closely spaced and their hydration levels can be determined by measuring the soil moisture at one location that overlaps with another spot on the soil surface.
The RTC module operates on the same concept of time monitoring in the background as other electronic devices such as computers and smartphones; even when these devices appear to be turned off, they continue to keep track of the current time. The RTC module, on the other hand, is capable of exchanging time information with the Arduino board. On a specific day of the week, at a specific time of day, the Arduino is pre-programmed to turn on the water pump and turn off the water pump after a specified length of time.
Components Needed:
- Arduino UNO
- Water Level Sensor
- Moisture Sensor
- RTC Module (DS1307)
- LCD
- 4 LEDs
- Buzzer
- Relay
- Water Pump
- PCF8574
Component Details:
Arduino UNO:
- Arduino UNO is a programmable microcontroller board.
- It contains Atmel's ATMega328 as is based on that microcontroller.
- The Arduino board also contains an in-built voltage regulator to protect it from burning out and supports serial communication to help programmers.
- The Arduino board is culturally programmed through the Arduino App designed by the board's developers and the programming is done in C language.
- The Arduino App compiles code and interfaces the firmware into the Arduino hardware.
- Arduino UNO has 14 digital I/O pins out of which 6 are PWM pins as well.
- Arduino also takes analog inputs and has 6 analog input pins.
Figure # 1: Arduino UNO
Soil Moisture Sensor:
- The soil moisture sensor is a resistive sensor that consists of two electrodes with a small charge and the resistance in those electrodes is measured and then the resistance in between the soil is used to find the moisture levels.
- A soil moisture sensor normally comes equipped with an amplifier such as LM393. It has a VCC, GND and analog output pin.
Figure # 2: Soil Moisture Sensor
Water Level Sensor:
- The water level sensor is a module that helps calculate the amount of liquid in a container.
- When a liquid is present in the tank, the Submersible level sensor detects the hydrostatic pressure generated by the liquid.
- Since hydrostatic pressure is a measure of two variables, the first of which is the density of the fluid and the second of which is the height of the fluid, it is a useful tool.
Figure # 3: Water Level Sensor
RTC Module:
- RTC stands for real Time Clock and as the name suggests the module keeps track of time even when the external power supply is cut off.
- It has a battery cell installed within it for that purpose, moreover, it is capable of communication with other devices such as Arduino too.
Figure # 4: RTC Module
Relay:
- Relays are basically electrical or electromechanical switches that operate on the principle of magnetic field controlling the switching within the relay.
- A relay has two modes of operation, normally open and normally closed.
Figure # 5: 12V Relay
PCF8574:
- The PCF8574 is a silicon-based CMOS integrated circuit.
- Using the two-line bidirectional bus enables general-purpose remote I/O extension for the majority of microcontroller families (I2C).
- It is used in our project for I2C communication of LCD.
Figure # 6: PCF 8574
Proteus Simulation of Plant Watering System
Now, let's design the Proteus Simulation of Plant Watering System first and then will work on the Arduino Code.
- First of all, make sure that Proteus is installed on your computer and download all the necessary libraries for Proteus beforehand.
- For this project, you will need libraries for Arduino, LCD, RTC Module, Water Level Sensor and Soil Moisture Sensor. Make sure that you read how to use each library in Proteus as well.
- Open a new project on Proteus, import all the components required and place them within the working area or the blue line of Proteus.
- Select below components from Proteus Components' library:
Circuit Diagram and Working:
- Now, place these components in your Proteus workspace, as shown in the below figure:
- For the water level and moisture sensor, place a variable POT(potentiometer) at the test pin and place an RC filter at the output pins. (This is only for simulation purposes)
- Start with the input side of Arduino and connect the soil moisture, water level output pins to the A1 and A0 pins of Arduino respectively.
- To use the LCD for I2C communication, Place PCF8574 and connect with LCD.
- Connect the SDA and SCL pins of PCF8574 and the SDA and SCL pins of the RTC module with the SDA and SCL pins of Arduino.
- For the output side of Arduino, Connect the D7 to the relay controlling the pump.
- Connect the buzzer at D2 and the LEDs to their respective Arduino pins as well.
- Make sure appropriate power and ground are provided to each component. With that the making of the circuit on Proteus is complete.
Figure 7 shows the circuit diagram of the system. Proteus was used to simulate the circuit and Arduino App was used for the simulation of the Arduino code. The circuit was designed in a way that is easy to understand and further integrated easily. We will now go through a step-by-step guide on how the circuit was built.
Figure # 7: Proteus Circuit diagram
Arduino Code for Plant Watering System
A normal Arduino code has two main segments:
We will look at both of them separately here.
Declaration Code
- The first step in setting up our code is defining libraries, download if you don’t have any libraries already integrated in the Arduino App.
Figure # 12: Arduino Code
- The next step in the code is tone definition for buzzer and pin definition of variables being used in the project.
Figure # 13: Arduino Code
- After pin definition, the variables used must be defined so that Arduino knows where to find them and how to identify them.
Figure # 14: Arduino Code
- The next step is defining the system messages that will appear on the LCD.
- It is not necessary to define those messages in the setup, they can be easily defined within the main code but it is an easier way to define those beforehand and call them whenever needed.
- This is especially useful when a system message is used multiple times in the code.
Figure # 15: Arduino Code
- Now we define the objects being used in the project.
- The two objects being defined are the RTC module and LCD. In the syntax below we used 20x0 in the argument for the LCD, that is because there are no libraries for I2C LCDs and we had to turn a simple LCD into an I2C LCD by the means of PCF8574.
Figure # 16: Arduino Code
Void setup:
Now we start the programming of void setup.
- At first is the initialization of various components, such as initializing the RTC module and setting the time and date of RTC with respect to our computer.
- Wire initialization and library are used for I2C communication.
Figure # 17: Arduino Code
- The next step is defining the digital pins of Arduino being used as input or output pins and displaying the initial message on our LCD.
Figure # 18: Arduino Code
Void Loop:
- The first step in the loop is to read the date and time from the computer through the RTC and read the values from the sensor.
- Since this part of the program runs in the loop, Arduino will keep reading and refreshing the sensor inputs every time the loop starts.
Figure # 19: Arduino Code
- In the next segment of the code, we will check various conditions of the sensor values and RTC and actuate our outputs on the basis of these conditions.
- At first, we check the water level of the container, if it is below the set level, Arduino will actuate the buzzer to alarm the user of low tank on LCD.
Figure # 20: Arduino Code
- In the next step, we check the values of the moisture sensor and place the conditions in three categories, namely, moist soil, soggy soil and dry soil.
- The Arduino will light up the respective LED whenever its condition is true. Red LED for dry soil, yellow LED for soggy soil and green LED for moist soil.
- The LCD will also display respective messages for each of those conditions.
- The following code is for the condition of dry soil.
Figure # 21: Arduino Code
- The following code is for the condition of moist soil.
Figure # 22: Arduino Code
- And finally the code for the condition of soggy soil.
Figure # 23: Arduino Code
- In the next step of the code, we check the condition of time, whether it is time to water the plants or not and the condition of the water reservoir to see its level as well.
Figure # 24: Arduino Code
If you see the code closely, you may see the function of the right hour, which is called various times in the main code. The function code in itself is written at the bottom of the main code. This function is used for displaying the time and date on the LCD and also for fixing the date and time.
Results/Working
- Open Arduino and generate a hex file for that program.
- Put the hex file in the Arduino UNO board placed in Proteus.
- Run the simulation.
Figure # 8: Proteus circuit simulation when soil is soggy
Figure # 9: Proteus circuit simulation when soil is moist
Figure # 10: Proteus circuit simulation when soil is dry
Figure # 11: Proteus circuit simulation when soil is dry and it is time to water the plant
As you can see from figure 8 that our simulation is running according to the program set at Arduino. You can increase or decrease the values coming from the sensors through the Potentiometer.
So, that was all for today. I hope you have enjoyed today's lecture. If you have any questions, please ask in the comments. Thanks for reading.
Smart Irrigation System using Arduino UNO
Hello everyone, we are back with a new project and we hope you all are doing well. In this article, we will discuss a project named Smart Irrigation System using Arduino UNO. We will use different sensors to measure the environmental and crop parameters which are responsible for good production. We will also make the water pump system automatic which will open the water valve automatically according to the soil moisture of the crop.
We will discuss all points and concepts briefly in this article and also provide a Proteus Simulation to observe how it will work in the real world. Complete fully explained code and simulation are also provided below as you go ahead in this article. You can download it from there.
Smart Irrigation System using Arduino UNO
Let’s start with an Introduction:
Introduction
In the late decades, there has been a quick advancement in Smart Agricultural Systems. Show that agriculture has great importance worldwide. Indeed, in India for example, about 70 % of the people rely upon the vital sector of agriculture. In the past, irrigation systems used to be dependent on the mills to irrigate the farm by conventional methods without knowing the appropriate quantities of these crops.
These old systems are a major cause of the waste of large quantities of water and thus destroy some crops because of the lack of adequate quantities of water. However, with the recent technological developments, there have been innovative systems for irrigation without the farmer interfering in the irrigation process. We will discuss it in brief below.
We will do a simulation on Proteus 8 Professional Software.
Working
The working of this project is like, we will use a Soil Moisture sensor for measuring the moisture of Soil according to which water valves are controlled. When the moisture level gets below a threshold value, valves will open with the help of a relay or solenoid till the soil is well moisturized.
- The BMP180 sensor will measure the Atmospheric Pressure.
- The DHT11 sensor will measure the temperature and humidity of the climate.
- The MQ135 sensor will measure the Air Quality Index of the environment.
- LDR will measure the sunlight intensity.
- We will use a 20x4 LCD Screen for displaying the data gathered from the sensors.
- And the main thing, we will use an Arduino UNO microcontroller as the brain of the project.
In a used case, when the moisture level gets below a threshold value, valves will open with the help of a relay or solenoid for a required time interval.
Block Diagram
- Here's the Block Diagram of Smart Irrigation System:
Components Required
Here's the list of components used in this project:
- Arduino UNO
- BMP180 Sensor
- DHT11 Sensor
- LDR Sensor
- MQ135 Gas Sensor
- Soil Moisture Sensor
- 20x4 LCD Display
- PCF8574 remote 8-bit I/O expander for the I2C bus
- Breadboard.
- Jumper wires (Male to Male, Male to Female, Female to Male.)
Since we are designing a prototype of this project, we will use jumper wires instead of soldering.
You can use a Battery, Adapter or any DC source of 5-8v(recommendable).
Circuit Diagram
Since we are making a prototype of this project, we will make connections on the breadboard and avoid soldering the components. We will use male to male, male to female and female to female jumper wires.
Pins Connections
These are the pin connections of all components.

Arduino Libraries Required
You need to install these third-party Arduino Libraries, in order to interface sensors:
- Adafruit_BMP085.h
- DHT.h
- LiquidCrystal_I2C.h
We have added comments in the code for better understanding so it can be understood easily.
Note - Change the Address of the LCD Screen while you run the code in Proteus, change it to 0x20 instead of 0x27 or anyone else. In the real experiment, we can alter the address of the LCD by changing the configurations of A0, A1 and A2 pins of the PCF8574 module.
Proteus Libraries Required
We will show you a demo of this project as a simulation. We are using Proteus 8 Professional Software for the simulation.
Proteus Simulation Connections
- This potentiometer defines the soil water content in the proteus simulation.
- When the resistance is maximum at the test pin, the circuit shows zero volts across the voltmeter, which means the sensor is either in the dry ground or taken out of the ground, i.e. giving zero moisture value of the water content.
- And when resistance is zero, the circuit will show the maximum voltage across the voltmeter which indicates the sensor is inserted in a wet ground i.e. water contents in the soil are too high.
- This is important. We have attached the output pin with an LC filter. This filter is not required in real hardware implementation.
- We are using it in Proteus Simulation only as Proteus gives the peak-to-peak value and we have to convert that PP value into Vrms.
- If you are working on a real sensor then you don’t need to add this LC circuit.
- Similarly for Gas sensor, as we increase the potentiometer, in simulation it means good air quality.
Steps for Simulation
These are the steps for simulation. Follow them to create a fully working simulation.
- Download the Zip Files given at the start of this tutorial.
- Extract them in the LIBRARY folder. You will find it inside the Labcenter Electronics Folder.
- Go to Arduino IDE and open the code, go to Tools and select the board Arduino UNO.
- Go to Sketch and Click on Export Compiled Binary. It will create a compiled .hex file of the code which will be used as the main program in the simulation ahead.
- Open Proteus software and add components by searching like Arduino, DHT11, BMP180, 20x4 LCD, etc.
You can see the components listed here.
Note - We used a simple LED instead of the valve because the valve component is not available in the Software, simply replace the LED with a valve in a real project. Make connections according to the circuit diagram and add virtual terminals to Serial pins to see the readings and Data.
- Paste the Program File here for all the sensors.
- Paste the Compiled Binary File as a Program file of Arduino UNO.
- Run the simulation and you can see the readings by opening the virtual terminal.
Observations and Results
- In this simulation and project, you can see the sensor's information first in the terminal.
- After that, we are getting well organized and easily understood data on the terminal by every sensor according to code.
- According to the code, when the value of the soil moisture sensor gets less than a threshold value, the LED gets on.
This means when the soil gets dry the valve will open and water will be provided to the crops.
pH Sensor Library for Proteus
Hi guys, I hope you are good and doing well in your life. In this article, I am going to tell you about a new pH Sensor Library for Proteus. I hope you all will enjoy it and find it useful. We are all well aware of pH Sensors which are used for the detection of pH of different fluids. By knowing the pH of a liquid we can tell whether the liquid is acidic or basic. You can’t find a pH sensor in Proteus software, so we designed a pH sensor for simulation purposes. You can interface this pH Sensor with any Microcontroller, for example: Arduino, PIC Microcontroller, 8051 Microcontroller etc.
In this pH Sensor Library, I have added four different pH Sensors, which are used for the detection of the pH of any fluid. Since we can’t place real liquid and measure pH in this software, I have attached a test pin in the pH meter where you have to connect a potentiometer. The potentiometer will produce a reading from 0 to 1023, which will be mapped from 0 to 14 in the program code. We can predict the nature of the liquid. We will have a look at how to use these sensors below. So, here’s the list of all four pH sensors, I have added to this pH sensor library:
- PH METER
- PH METER 2
- PH METER 3
- PH METER 4
So, let’s start with downloading and installing the pH Sensor Library for Proteus.

What is a pH Sensor?
- A pH sensor is a device that is used to measure the pH value of a liquid. pH can be defined as the concentration of H+ ions in a liquid. We can find whether the fluid is acidic, basic or neutral by knowing the pH of the liquid.
- Real pH sensors are shown below:
pH sensor Library for Proteus
- First, download the zip file of Proteus Library for pH Sensor.
- Click the link below to download the library zip file of pH Meter:
pH Sensor Library for Proteus
- After downloading the zip file, extract its files and open the folder named “Proteus Library Files“.
- In this folder, you will find three files, named:
- pHMeterLibraryTEP.IDX
- pHMeterLibraryTEP.LIB
- pHMeterLibraryTEP.HEX
- We have to place these files in the ‘LIBRARY’ folder of Proteus software.
- Now, open Proteus. if you are already working on it you have to restart it.
- In the components search box, search for “PH METER” and you will get four results, as shown in the below figure:
- Let’s place these four pH Meter models in our Proteus workspace:
Adding Hex File to the Sensor
- Now we need to paste the hex file of the pH METER in the properties section of the sensor. Double click on the sensor to open the properties window.
- Go to the program file section, browse to the hex file, which we have downloaded above and placed it in the ‘LIBRARY’ folder of Proteus software:
- After adding the hex file, click the Ok button.
- Now all is ready, let’s create a circuit to check it's working.
pH Sensor Proteus Simulation
- The pH sensor is now ready to simulate in Proteus, so let’s design a simple circuit to understand its working:
- As you can see, I have placed an LC filter on the analog output of the pH sensor, it's because proteus gives us a peak to peak voltage value and we need to convert it to Vrms.
- While performing the real experiment, you don’t need to do the above stuff.
- Now, let’s run the Proteus simulation. You will see such a screen if everything will work fine.
Interfacing of pH sensor with Arduino UNO
- Add Arduino UNO and pH sensor to the components list and place them in the workspace.
- Placed an LC filter on the analog output of the pH sensor, as mentioned above.
- Connect it to the A0 pin of Arduino. Add a virtual terminal also to see the readings generated.
- Paste the hex file of the program at the program file section of the Arduino.
- Now run the simulation, if everything's fine you will get results as shown in the below figure:
- You can watch the complete working simulation in the below video:
So, that was all for today. I hope you have enjoyed today's lecture. Thanks for reading !!!

Know that Test Pin is included in the pinout of this sensor in proteus only, you won’t find this pin in the real sensor. This pin will determine the value of the bend. The HIGH value at this pin will give the value of bend and the LOW value at this pin will indicate there is no bend. We have also interfaced the Arduino board with the sensor where the analog input pin of the board is connected with the voltage appearing across the voltmeter.

Soil Moisture Sensor Library for Proteus
A soil moisture sensor is employed to analyze the water content in the soil. The sensor uses capacitance to monitor the dielectric permittivity of the soil which defines the function of the water content.
We have designed the Soil Moisture Sensor Library for Proteus where we have connected the test pin with the variable resistor. This resistor is used to define the soil moisture content in the proteus simulation. The maximum resistance on the test pin shows zero volts across the voltmeter, referring to the zero moisture value of the water content. The sensor is also interfaced with the Arduino board as shown below.

IR Proximity Sensor Library for Proteus
The IR proximity sensor is used in robots to detect obstacles. This sensor is widely used for path navigation and obstacle avoidance in electronic projects.
We have designed the IR Proximity Sensor Library for Proteus which you can download to simulate this sensor in Proteus. The Test pin is used for hurdle detection. HIGH value on this pin means there is an obstacle in front and LOW value on this pin means there is no hurdle.
LC filter is included in the simulation which you don’t require in real. This filter is used to convert the Peak to Peak value we get on Proteus into the Vrms value.

Soil Moisture Sensor Library for Proteus V2.0
Hello friends, I hope you all are doing fine. In today's tutorial, I am going to share a new Soil Moisture Sensor Library for Proteus V2.0. You should also have a look at its previous version i.e. Soil Moisture Sensor Library for Proteus V1.0. If you have worked on the previous version, it has only one soil moisture sensor in it, while in this library, we have added three soil moisture sensors.
First, we will have a brief introduction of the Soil Moisture sensor, then we will download the zip file containing Proteus Library files of Soil Moisture Sensor and finally, we will design a small simulation using these new sensors. So, let's get started:

What is Soil Moisture Sensor?
- Soil Moisture sensor is an embedded sensor, used to measure the moisture level of the soil.
- It is normally used in agricultural automation projects, i.e. controlling the water flow based on the moisture level of the soil.
- Soil Moisture sensors are available with both analog and digital outputs.
- They normally have a potentiometer embedded in them, for controlling the sensitivity of the sensor.
Before downloading the sensor's library file, let's first have a look at what's new in version 2.
Difference b/w V1.0 & V2.0
- We received many complaints about the big size of the Soil Moisture sensor(V1.0), so we have reduced their sizes in this new library(V2.0).
- The first version contains only 1 soil moisture sensor, while in V2.0 we have added three soil moisture sensors.
- The output of V1.0 was quite smooth, while in V2.0 we have made the output a bit fluctuating to make it more realistic.
Now, let's download the Proteus Library zip file for this sensor and simulate it in Proteus:
Soil Moisture Sensor Library for Proteus V2.0
- First, we need to download the Proteus Library zip file, by clicking the below button:
Soil Moisture Sensor Library for Proteus V2.0
- After downloading the zip file, extract it and open the folder named Proteus Library Files.
- You will find three files in this folder, named as:
- SoilMoistureSensor2TEP.IDX
- SoilMoistureSensor2TEP.LIB
- SoilMoistureSensor2TEP.HEX
- Place these files in the library folder of your Proteus software.
Note:
- Now, open Proteus ISIS, and if you are already working on it, then restart it.
- In the components library, make a search for Soil Moisture Sensor, and you will get results as shown in the below figure:
- Let's place these three soil moisture sensors in the Proteus workspace:
- Quite pretty, aren't they? :)
Now let's design a small simulation, to have a look at its working:
Proteus Simulation of Soil Moisture Sensor
- As you can see in the above figure, each of these sensors has 4 pins in total, which are:
- Vcc: We need to provide +5V here.
- GND: We need to connect it to Ground.
- A0: It's the analog output pin, its value will increase as the moisture level of the soil will increase.
- TestPin: The voltage level of TestPin will decide the moisture level of the soil.
Why Test Pin is used?
- As it's a simulation, so we can't actually probe the sensor in real soil, so we are using this TestPin for testing purposes.
- The value of Test Pin can vary from 0 to 5V, so as the value of this Test Pin will increase, the sensor will consider the moisture level of the soil in increasing and thus its output will also increase. In simple words:
- If TestPin is HIGH: Soil has maximum moisture level.
- If TestPin is LOW: Soil is completely dry.
- We will place a potentiometer at TestPin to provide variable voltage for testing.
Adding Hex File to the sensor
- We have placed three library files of soil moisture sensor in the Library folder of Proteus, and if you have noticed, one of them is the .hex file.
- In order to operate this sensor, we need to add that hex file to our sensor.
- So, double click on the Soil Moisture sensor to open its Properties Panel.
- In the properties panel, we have a section named "Program File", here upload the hex file which we have downloaded, as shown in the below figure:
- After adding the hex file, click Ok to close the properties panel.
- Now, design a small simulation, as shown in the below figure:(I have added this simulation in the Proteus Library zip file)
- I have added the hex file in both of these soil moisture sensors.
- Now, let's run the Proteus Simulation and have a look at the output:
- As we change the value of the potentiometer(attached to Test Pin), the output of the sensor will change accordingly.
So, that was all for today. I hope this library will help embedded students in their engineering projects. If you have any suggestions/comments, please use the below comment form. Thanks for reading. Take care. Bye !!! :)
Soil Moisture Sensor Library For Proteus
Update: We have created a new version of this library, which you can check here:
Soil Moisture Sensor Library for Proteus V2.0.
Hi Friends! Hope you’re well today. I welcome you on board. In this tutorial, I’ll be discussing the Soil Moisture Sensor Library for Proteus. You won't find Soil Moisture Sensor Library in Proteus and we’re going to share its Proteus Library very first time. I have previously shared many Proteus Libraries for digital and analog sensors and today I’m discussing something new. Excited to get a hold of the Soil Moisture Sensor Library? Me too. In the upcoming days, I’ll keep sharing different libraries related to sensors. If you’re curious to sneak into the nitty-gritty of sensors not available in the Proteus library already, pop your suggestion in the comment section below. I’ll try my best to comply with your suggestions and walk you through something brand new.
Soil moisture sensors are used to measure the water content in the soil. They use capacitance to measure the dielectric permittivity of the soil which defines the function of the water content. Before further ado, let’s dive in and have a look at How to download and simulate Soil Moisture Sensor Library for Proteus:

Soil Moisture Sensor Library For Proteus
- You can download the Proteus Library zip file of Soil Moisture Sensor Library by clicking the button below.
Download Proteus Library Files
- It’s a .zip file that contains two folders inside i.e. Proteus Library & Proteus Simulations.
- The real fun starts right here right away.
- Open proteus library folder that contains three files named:
- SoilMoistureSensorTEP.IDX
- SoilMoistureSensorTEP.LIB
- SoilMoistureSensorTEP.HEX
- Copy and paste these three files in the Library folder of your Proteus software:
- Now, we need to run the Proteus ISIS software and don't forget to restart, if it's already open.
- Look for the Soil Moisture in the component’s search box as shown below.
- After installing the Library successfully, you’ll get similar results as below:
- You can see in the figure above we have one Soil Moisture Sensor.
- Now simply place this Soil Moisture Sensor in your Proteus workspace, as mentioned below:
- You can see in the figure above, I have placed one Soil Moisture Sensor inside the Proteus workspace.
- This sensor carries 4 pins in total, named:
- V (Vcc): We’ll provide +5V here.
- G (GND): We’ll provide ground here.
- Ao (Out): It’s an analog output signal from the sensor.
- TestPin: It is used for simulation purposes only. Soil Moisture Sensor doesn’t contain this pin in real.
Adding Sensor’s Hex File
- After this drill, we’ll add the Sensor’s Hex File, which we have downloaded and placed in the Library folder.
- To do that, right-click on your Soil Moisture Sensor and then click on “Edit Properties” as below:
- Or you can double click the Soil Moisture Sensor, it will pop the window below:
- Click on the Browse button and add SoilMoistureSensorTEP.HEX file available in the Proteus Library section as shown in the figure below:
- After adding the Sensor’s Hex File, click on the ‘OK’ button to close the ‘Edit Properties’ Panel.
- Our Soil Moisture Sensor is now ready to simulate in our Proteus ISIS.
- We’ll design a small circuit to thoroughly understand the working of this Soil Moisture Sensor.
Proteus Simulation of Soil Moisture Sensor
- Here, I’m designing a simple circuit. I’ve attached a variable resistor with the Test Pin & added a Voltmeter at the Output pin, as shown in the figure below:
- This resister defines the soil water content in the proteus simulation.
- When the resistance is maximum at the test pin, the circuit shows zero volts across the voltmeter, which means the sensor is either in the dry ground or taken out of the ground i.e. giving zero moisture value of the water content.
- And when resistance is zero, the circuit will show the maximum voltage across the voltmeter which indicates the sensor is inserted in a wet ground i.e. water contents in the soil are too high.
- This is important. We have attached the output pin with an LC filter. This filter is not required in real hardware implementation.
- We are using it in Proteus Simulation only as Proteus gives the peak-to-peak value and we have to convert that PP value into Vrms.
- If you are working on a real sensor then you don’t need to add this LC circuit.
- Now, let’s run this Proteus Simulation and if you have done everything as mentioned, it will show the result mentioned in the figure above.
Simulation of Soil Moisture Sensor with Arduino
Now, let's interface this sensor with a
microcontroller.
- We have attached the output of the sensor appearing across the voltmeter with the A0 pin of the microcontroller as below.
You can see we get the analog value 1019 when the voltage across the voltmeter is 4.98V
This is it. I hope you find this tutorial helpful. This will help engineering students in simulating their semester projects in proteus. In the next tutorials, I’ll be sharing and adding more libraries of sensors. You’re most welcome to share your suggestions with the sensors you want me to libraries of. If you’re unsure or have any questions, you can ask me in the section below. I’ll help the best way I can. Thank you for reading this article.
