Top 10 Arduino Sensors

Description:

Top 10 Arduino Sensors– A sensor is a device, Module, Machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics. A sensor is always used with other electronic circuits or microcontroller boards. There are thousands of sensors used for different purposes. It’s not possible for me cover all the sensors in one article. But,

In this Article, I am going to share with you Top 10 Arduino sensors, which I believe you should learn how to use them. The Sensors I am about to share with you guys can be used in beginner’s level and advanced level projects.

Note: Watch video tutorial given at the end of this article. Don’t forget to subscribe my YouTube channel.

Without any further delay let’s get started!!!

Arduino MPU6050 Sensor:Top 10 Arduino Sensors

This is the GY-521 MPU6050 6DOF 3-Axis Gyroscope and Accelerometer Module. The MPU6050 communicates with the Arduino through the I2C protocol. The MPU6050 always acts as a slave to the Arduino with the SDA and SCL pins connected to the I2C bus. This module needs 3 to 5 volts. This Module can be used in a hand gesture controlled Robot, wheelchair, earthquake detection system, Self-balancing Robot, a self-balancing platform for a camera, Segway, Drivers drowsiness detection system, etc.

The MPU6050 sensor can be used in projects where you need to measure the angle or rotation of any object. A few days back I uploaded two videos.

In the first video, I covered the extreme basics, in which I explained the basic circuit diagram, Soldering and beginner’s level programming.

While in the second video I used the MPU6050 Sensor in the Drivers accident protection system.

In this episode, you will learn how to reduce distracted driving accidents using only Arduino, MPU6050 and a buzzer. If a driver writes a message and looks down for more than 2 seconds the buzzer is activated… So, if the driver looks down or looks up for more than 2 seconds a buzzer is activated which alerts the driver… This project can also be used as the driver drowsiness detection system… This is just a prototype model which can be further improved by designing a PCB.



pH Sensor:

Top 10 Arduino Sensors

This is the Analog pH Sensor which is most commonly used for measuring the water quality. I have already uploaded two videos on the Analog pH Sensor

In the first video, you will learn how to use the pH sensor with Arduino and find the pH value of different liquids and display the pH value on the serial monitor. In this video, I have tried to cover the extreme basics like for example,

  1. How a pH sensor work
  2. Application of pH meter
  3. pH sensor Calibration
  4. pH sensor interfacing with Arduino
  5. Basic programming to find the pH value of different liquids and finally
  6. Testing

As this is an IoT “Internet of Things” based project, the water quality can be monitored from anywhere around the world. In this episode, I have practically explained how to measure the pH value of the Well water, and I have also explained whether the water under test is good or bad for health. In this tutorial, you will also learn how to use the 16×2 LCD widget in the Blynk application.


Magnetic Hall Effect Sensor:

Top 10 Arduino Sensors

This is the Magnetic Hall effect Sensor, which can be used in projects where you need to detect the presence of a permanent Magnetic or Electromagnet.  The Magnetic Hall Effect sensor can be used in measuring the speed; it can be used in contactless control systems. This Sensor is usually used in locations where you don’t need to make any contact.

 

 

Recently, I have uploaded a video in which you will learn how to make an electronic glove based on the magnetic Hall Effect sensor, Arduino, and 433 MHz Radio Frequency Modules; to protect workers from coming into contact with the moving parts or getting caught in the machinery.  For the demonstration purposes, I am using two indicator lamps. When the worker gets too close to the moving part the machine turns off and an alarm is activated which is represented by the yellow indicator lamp.

This is just a prototype model which can be further improved by designing some very small size Magnetic Hall Effect sensors, we can also include some pressure sensors and the wires can be made hidden inside the gloves. Using such gloves we can perform ordinary tasks without any problem as these gloves are completely Wireless.

 

 

I have also used the Magnetic Hall Effect Sensor in the Tongue controlled wheelchair. In this project, the Wheelchair movement is wirelessly controlled with the help of the tongue movement.
