Different Types of Sensors

May 16, 2024


The following is a list of different types of sensors that are commonly used in various applications. All these sensors are used for measuring one of the physical properties like Temperature, Resistance, Capacitance, Conduction, Heat Transfer etc.

  1. Temperature Sensor
  2. Proximity Sensor
  3. Accelerometer
  4. IR Sensor (Infrared Sensor)
  5. Pressure Sensor
  6. Light Sensor
  7. Ultrasonic Sensor
  8. Smoke, Gas and Alcohol Sensor
  9. Touch Sensor
  10. Color Sensor
  11. Humidity Sensor
  12. Position Sensor
  13. Magnetic Sensor (Hall Effect Sensor)
  14. Microphone (Sound Sensor)
  15. Tilt Sensor
  16. Flow and Level Sensor
  17. PIR Sensor
  18. Touch Sensor
  19. Strain and Weight Sensor

We will see about few of the above-mentioned sensors in brief. More information about the sensors will be added subsequently. A list of projects using the above sensors is given at the end of the page.

Temperature Sensor

One of the most common and most popular sensors is the Temperature Sensor. A Temperature Sensor, as the name suggests, senses the temperature i.e., it measures the changes in the temperature.Types of Sensors Image 3

Temperature Sensors are used everywhere like computers, mobile phones, automobiles, air conditioning systems, industries etc.


Proximity Sensors

A Proximity Sensor is a non-contact type sensor that detects the presence of an object. Proximity Sensors can be implemented using different techniques like Optical (like Infrared or Laser), Sound (Ultrasonic), Magnetic (Hall Effect), Capacitive, etc.Types of Sensors Image 4Some of the applications of Proximity Sensors are Mobile Phones, Cars (Parking Sensors), industries (object alignment), Ground Proximity in Aircrafts, etc.

Light Sensor

Sometimes also known as Photo Sensors, Light Sensors are one of the important sensors. A simple Light Sensor available today is the Light Dependent Resistor or LDR. The property of LDR is that its resistance is inversely proportional to the intensity of the ambient light i.e., when the intensity of light increases, its resistance decreases and vise-versa.

By using LDR is a circuit, we can calibrate the changes in its resistance to measure the intensity of Light. There are two other Light Sensors (or Photo Sensors) which are often used in complex electronic system design. They are Photo Diode and Photo Transistor. All these are Analog Sensors.latest company news about Different Types of Sensors  2

In this article, we have seen about What is a Sensor, what are the classification of sensors and Different Types of Sensors along with their practical applications. In the future, I will update this article with more sensors and their applications.
