Apps Are Saving Lives in the Wilderness

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll detail how apps are saving lives in the wilderness. Whenever disaster strikes in the wilderness, be it from fires, storms, or other natural disasters, it can be a daunting task for people and animals to get the help they need to get out of potentially life-threatening circumstances. Animals, particularly endangered species, get caught in all kinds of situations that require attention, but obviously, they can’t just pick up the phone and call for help, and for people, they might not have the means to fare much better if their phones are out of service or they get injured and can't move. When it comes to wildlife rescue operations and conservation, location-based apps can actually make a huge impact and may lead to lives being saved thanks to the services they provide.

How Apps Can Get the Right Help Notified

Wildlife rangers and emergency service teams take to the field to resolve issues including natural disaster assistance and rescue. Thanks to location-based apps, their jobs can be made a whole lot easier because they can quickly find people in need and can evaluate injuries of wildlife right on their phones directly. Some quintessential features include GPS and location-based data, and location based app development takes these into account when they create apps that are meant to be used in emergency situations. This not only helps rescue operatives, but also everyday users who might be stuck in certain situations or come across injured wildlife. For example, the Animal Help Now! the app allows you to quickly make a call to the nearest rescue center or rehabilitation facility, while also providing helpful tips that anyone can understand.

The Uses of Location Data

Location data allows users to quickly find out where they are in relation to the surrounding area, and send out signals to nearby areas of assistance. By using geolocation, tracking, and GPS functions, rangers are able to expedite the process of getting people and wildlife the help they need by pinpointing an exact location and contacting the proper emergency responders. Some GPS data can be used without a phone signal or wifi, making it so that even in remote areas, help can still arrive thanks to these apps giving a general read of a victim’s location. This helps in situations where a quick response is necessary, and contacting the right help leads to reduced suffering and lives saved. For example, the ISOS Emergency App on Android is able to send an alert to contact with your current location, complete with alarms and area-specific emergency service list. Not only do these apps provide location data, but they can also be informative outside emergency scenarios. They can provide warning messages, displays of information on how to properly handle injured animals, and help them identify where help is immediately needed. Emergency services can use these apps to pinpoint trouble areas and respond quickly, but the apps aren't limited to being helpful just for them. Thanks to these location-based apps, anyone has the means and resources to help those in need, and lives can be saved as a result. Hope you find this read useful. Thank you for reading the article.

Why Cybersecurity in the Healthcare Industry is Vital

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through why cybersecurity in the healthcare industry is vital. The days of keeping records with pen and paper and storing the information into a file cabinet are gone.  Now, we can effectively keep confidential information since technology saves both space and time, and it is more accessible. The only problem with this new trend seen in the last couple of decades is the security issue.  The healthcare industry, one of the most important industries in the world,  contains information that must stay in safe hands, away from the eyes of hackers. Below are some reasons why healthcare and healthcare cybersecurity professionals are so mindful to protect this information.

Reputation

When you go to a hospital or go to see your family physician, I bet you don’t worry about your information getting accessed or released to people that should know your situation. The reason for this is because that is the biggest priority of healthcare workers because if they did have a data breach, you would probably not go back to that place and they would lose potential patients. The reputation of a healthcare institution is at stake if they find it hard to protect your information because that is private, and it is unacceptable for some people if they get to know someone has accessed their information. Protecting a hospital’s reputation is so important for all parties involved because once a reputation is ruined, it is hard to earn it back.  In any business relationship, when trust is lost it is almost impossible to get back in sensitive topics like health history.

HIPAA

Another aspect of the healthcare industry that must be highlighted is HIPAA compliance.  In general terms, HIPAA was created to protect the information of patients and give patients peace of mind that their information is safe from the general public. There are components of HIPAA that make any security breaches a problem and not in compliance with the guidelines.  Security is a major proponent and it is even worse to have a security breach since HIPAA is obviously going to frown upon any kind of security issue. For more information in regards to HIPAA, you can check out some of the pretty neat HIPPAA compliance software development that is being developed as we speak. Those two reasons alone are some of the biggest reasons why the healthcare industry must protect their information and patient information at all costs.  All it takes is one data breach for all trust to be lost and patients to not ever trust that facility again. Cybersecurity is taking major steps in this industry to protect information at all costs, and hopefully, we will never have to deal with a large security breach, and millions of records are compromised. Hopefully, now that you have read this, you now know how vital security is to the healthcare industry and the weight that it holds.  Please share this post if you find it interesting. Thank you for reading this post.

Introduction to Arduino Sensor Shield

Hi Guys! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to Arduino Sensor Shield. Arduino Sensor Shield is a board compatible with the Arduino Boards and comes with the standard header layout. It is used to connect sensors, servos, LCD with the Arduino board without soldering. This board is connected with the Arduino Board using the jumper wires. I suggest you read this post all the way through as I’ll be discussing the complete Introduction to Arduino Sensor Shield. Let’s get started.

Introduction to Arduino Sensor Shield

• Arduino Sensor Shield is a board used to connect sensors, servos, LCD with the Arduino Board without the requirement of soldering.
• Using Arduino Board separately you’ll find a few of 5V and GND connections. Arduino Sensor Shield gives you the ability of dedicated one 5V and GND connection for every Arduino signal pin.

• Arduino.cc introduced the two versions of Arduino Sensor Shield i.e. V4 the old one and V5 the newer one. Both boards come with similar important connections, however, they appear different.

• The V5 latest sensor shield comes with an external power connector, helping you get rid of the overloading of the Arduino board while working with too many actuators and sensors.
• The 3-way male pin header is used to connect servo motors with the Arduino Board. This is a plug and play device. You can read data from the sensors connected with the shield and use it to drive servo motors with the Arduino boards.

1. Pins Distribution

Pins on the Sensor Shield are distributed into two main categories: a: Digital Pins b: Analog Pins

a. Digital Pins

Digital pins on the board are placed in the pack of three.

• Where top pin represents GND (0V)

• The middle pin represents Vcc (5V)
• The bottom pin represents Signal (Arduino Digital Signal Pin No.)

The following figure shows the numbering of digital pins that are arranged from right to left on the board. The Digital Pins are configured from the following Arduino Language Instruction:

• digitalWrite (Pin4,1);

And for reading following Arduino Language Instruction is used:

• digitalRead(Pin4)

b. Analog Pins

The following figure shows the arrangement of Analog Pins that are sequenced from left to right.

• Similar to digital pins, analog pins are also arranged in the pack of three.
• Where the top one is GND (0V)
• The middle one is Vcc (5V)
• The bottom one is Signal (Arduino Analog Signal Pin No.)

2. Arduino Sensor Shield V5 Features

The following are the features of Arduino Sensor Shield V5.

• The Arduino Sensor Shield V5.0 is used to connect sensors, servos, buttons, relays, and potentiometers with the Arduino Board. Incorporates IIC interface
• Comes with RB URF v1.1 ultrasonic sensors interface
• It is compatible with Arduino UNO and Mega Boards

• Contains Bluetooth module communication interface
• Carries SD card module communication interface
• Contains APC220 wireless RF module communication interface
• Carries 32 servo controller interface
• Contains 128 x 64 LCD parallel interface

3. Connecting Sensors and Output Devices

When it comes to connecting the sensor shield with sensors and output devices, power pins must be connected the right way as follows

• G goes to 0V or G or Gnd or GND on the sensor
• V goes to 5V or V or Vcc or VCC on the sensor

• S goes to the signal pin - IN or OUT
• Some output-devices and sensors come with 2 signal pins (or more) with two or more 0V & +5V.
• In that case pick one of the signal pins to connect the Signal, 0V, and +5V with the S, G, and V pins on the sensor shield and choose the S pins on another port for establishing the other signal connections.

4. Photo-Resistor Sensor

Some sensors like 4-wire Photo-resistor Sensor comes with 2 wires for power, as above, but carry two signal pins, one is marked as “DO” and another is marked as “A0” This is the same signal available in two versions.

a. Analog Signal

• The AO is an analog signal that represents the light level where 0V shows the maximum light level and 5V shows the dark light.
• analogRead instruction is used to read this signal and is commonly connected to the analog input of the sensor shield.
• The A0 analog signal is read as 1023 for dark light and 0 for maximum light.

b. Digital Signal

• The DO is a digital signal that represents the light level and is available in two different states i.e. logic low (0V) and logic high (5V)
• The variable resistor available on the sensor module is used to set the switchover level. This digital signal is commonly connected to the digital input on the sensor shield.
• The digitalRead instruction is used to read this signal where 1 represents the dark and 0 represents the light.

SR5100 Schottky Rectifier Datasheet, Pinout, Features & Applications

Hi Friends! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to SR5100. The SR5100 is a Schottky diode used to generate extremely fast switching. It is also called a hot-carrier diode and is protected against overvoltage. It comes with a high surge current capability and low forward drop voltage. It contains a forward rectified current around 5 A and terminal resistance around 28 C/W. It is available in epitaxial construction with a peak reverse voltage of around 100 V. You are most welcome to see the Introduction to 1n4744 and Introduction to 1n4742 that I have uploaded recently. Read this post all the way through as I’ll detail the datasheet, pinout, features, and applications of this tiny component SR5100. Keep reading.

Introduction to SR5100

• The SR5100 is a Schottky diode, also known as a hot-carrier diode, used to produce extremely fast switching.
• MOSFETs can be used in place of these Schottky diodes where we need less power dissipation.

• Schottky diode and regular diode are slightly different in terms of voltage needed to power up these diodes. The Schottky diode needs only 0.3V out of 2V DC source voltage, leaving behind 1.7V to power the diode. While a regular diode needs only 0.7V, leaving behind 1.3V to power the diode.

• Schottky diode is also called a hot-carrier diode since it forms a barrier in an unbiased condition where electrons carry low energy on the semiconductor material that results in the formation of a barrier. The reason Schottky diodes are also called a hot-carrier diode.

SR5100 Datasheet

While working with any electronic component, it’s always better to go through the datasheet of the component that highlights the main characteristics of the device. Click the link below to download the datasheet of the SR5100.

SR5100 Pinout

The following figure shows the pinout diagram of SR5100.

• SR5100 is made of two terminals that are mainly used for the external connection with the electronic circuit.
• These terminals are known as anode and cathode. The cathode is negative from where the current leaves the diode and the anode side is positive from where the current enters the diode.
• The current moves from the anode pin to the cathode pin. The anode side is composed of metal and the cathode terminal is made of semiconductor material.

SR5100 Features

The following are the main features and absolute maximum ratings of SR5100.

• Contains low forward drop voltage
• Capable of generating high current
• Comes with high surge current capability
• Available in epitaxial construction

• Comes with high reliability
• Peak reverse voltage Max. = 100 V
• DC blocking voltage Max. = 100 V
• Average forward rectified current Max. = 5 A
• Thermal resistance = 28 C/W
• DC reverse current Max = 0.5 mA
• Storage temperature range = -65 to 175 C

You can see this tiny component comes with low forward drop voltage and is capable of generating high current. It carries high reliability with both peak reverse voltage around and DC blocking voltage around 100 V. Thermal resistance is 28 C/W and DC reverse current is 0.5mA with a storage temperature range -65 to 175 C.

SR5100 Schottky Diode Construction

• The SR5100 Schottky diode is made of metal and semiconductor material. Though both n-type and p-type semiconductor materials can be used, n-type material is preferred over p-type since the later comes with low forward drop voltage.
• When n-type material is combined with the metal like molybdenum, platinum, chromium, and tungsten, it results in the making of Schottky diodes.
• In the Schottky diode, there are two terminals used for external connection with the circuit. These terminals are known as anode and cathode. The anode side is positive and is made of metal while the cathode side is negative and is made of semiconductor material. The current flows from the anode side to the cathode side. And anode is the terminal from where the current enters the diode and the cathode is the terminal from where it leaves the diode.

• The forward drop voltage of the diode is mainly dependent on the nature of metal and semiconductor material used for the formation of a barrier. Low forward drop voltage leads to less energy released as heat that makes this diode an ideal pick for the applications sensitive to efficiency.
• These diodes are incorporated in the solar systems that keep the batteries from discharging in the absence of solar heat coming from the sun.

SR5100 Applications

• Used in freewheeling and logic circuits.
• Used in stand-alone photovoltaic systems.
• Can be used to control the electronic charge.
• Used in high-frequency and low voltage inverters.
• Employed in sample-and-hold circuits.
• Used for signal detection and radio frequency applications.
• Employed in extremely fast switching applications.
• Employed in DC/DC converters and polarity protection applications.

• Schottky diode and regular diode are two different components in terms of voltage needed to power up these devices.

• The Schottky diode requires only 0.3V out of 2V DC source voltage, leaving behind 1.7V to power the diode. While, on the other hand, a common diode requires only 0.7V, leaving behind 1.3V to power the diode device.

• Schottky diode is also called a hot-carrier diode since when the metal anode is combined with a semiconductor material, it results in the creation of a barrier. The reason Schottky devices are also called a hot-carrier diode.
• MOSFETs replace these Schottky diodes where less power dissipation is required.

• SB5100 is a two-pin device, these pins are also called terminals. Where one pin is the anode and the other pin is the cathode used for the external connection with the electronic circuit.
• The cathode pin is negative and is the area from where the current leaves the diode and the anode pin is positive and is the place from where the current enters the diode.
• The current moves from the anode terminal to the cathode terminal. The anode positive pin is composed of metal and the cathode negative pin is made of semiconductor material.

SB5100 Schottky Diode Construction

• The SB5100 is a Schottky diode composed of metal and semiconductor material. The N-type semiconductor material is used in the construction of the Schottky diode. When n-type material is combined with metals like tungsten, molybdenum, platinum, chromium, it creates the Schottky diode.
• It is important to note that both p-type and n-type semiconductors can be employed along with the metal, but n-type materials are preferred over p-type materials since the later carries low forward drop voltage.
• This Schottky diode is a two-terminal device. These terminals are known as anode and cathode terminal. The anode is a positive side that is composed of metal material and the cathode side is negative that is made of semiconductor material.
• The forward drop voltage of the diode is directly related to the nature of semiconductor material and metal employed for the formation of a barrier. Low forward drop voltage results in the release of less energy as heat, making this diode suitable for the applications sensitive to efficiency.

These devices are also employed in the solar systems that keep the batteries from discharging in the absence of solar energy.
