What is IR Tracker Sensor???

• IR Tracker Sensor uses Infrared technology and contains two IR LEDs on it.
• A signal is transmitted from one LED, which is reflected back after hitting some target and is received by the second LED.
• This sensor is normally used in Line Tracking Robotic Projects, where the black line is sensed by this IR Tracker sensor.

Infrared Tracker Sensor Library for Proteus

• First of all, download the zip file of Proteus Library by clicking the below button:

• Once you downloaded the zip file, extract it and open the folder named "Proteus Library Files".
• You will find three files in it, named:
  • InfraredTrackerSensorTEP.IDX
  • InfraredTrackerSensorTEP.LIB
  • InfraredTrackerSensorTEP.HEX
• Place these three files in the Library folder of your Proteus software.

• If you are facing problems with adding a library in Proteus 7 or 8 Professional, then have a look at How to add a new Library in Proteus 8 Professional.

• Now open your Proteus software or restart it, if it's already running.
• In the components section, we need to make a search for Infrared Tracker Sensor, and you will get results as shown in the below figure:

• As you can see in the above figure, now we have 4 infrared tracker sensors in our Proteus database.
• Let's place these sensors in the Proteus workspace, that's how they will look like:

Adding Hex File to the sensor

• Now we need to add the hex file to the sensor, so double click on the sensor to open its Properties Panel.
• In the properties panel, we have a textbox named "Program File".
• In this textbox, browse to the hex file of the sensor, which we have placed in the Library folder of Proteus software, as shown in the below figure:

• After adding the hex file, click the OK button to close the properties panel.

Infrared Tracker Sensor Pinout

• As you can see these sensors have five pins in total, which are:
  1. V: Power.
  2. G: Ground.
  3. D0: Digital Output.
  4. A0: Analog Output.
  5. Test: For Testing Purposes.

Why Test Pin is used?

• As it's a simulation, so we can't actually generate IR pulses, that's why I have placed this Test Pin.
• As the voltage at Test Pin will increase, the sensor will consider it as the obstacle is coming close.
• We will place a potentiometer at this Test Pin.
• This Test Pin is not present in a real IR Tracker sensor.

Infrared Tracker Sensor Proteus Simulation

• Design a simulation in Proteus, as shown in the below figure:

• I have placed an LC circuit in front of the analog output because we have to convert the peak to peak voltage to Vrms.
• This LC filter is also not required in real hardware, but in simulation, we need to place it to get an analog value.
• Now, let's run our Proteus simulation of the IR sensor and if everything goes fine, you will get results as shown in the below figure:

• I have simulated two of these sensors, the rest will work the same and as you can see depending on the potentiometer, we got different values at the output.
