What is Sensor and types of sensor

sensors and types of sensors

In this article we are going to explain Types of Sensor shortly. A Sensor is a device or detector that converts a physical parameter into a signal that can be monitored or measured. For example a GAS Sensor monitors gas gathering (PPM) and changes it into electrical signal that can be measured. The input parameter can be separate like Light, Temperature and Humidity pressure. But the output is normally a human-readable Temperature or electrically monitor able.

Sensor and types of Sensors

Definition of Sensor

Definition According to Oxford dictionary, a Sensor is “A device which measures or detects  a physical property and indicates, records, or otherwise answer to it.”

Meaning of Sensor  Wikipedia “A sensor is an object whose purpose is to changes or detect incident in this environment, and then issue a corresponding output”

Types of Sensor

A sensor is classified according to their structure and features. We classified normally such as:

  • Output Based : Differential output, Resistive output, voltage output etc
  • Parameter Sensing Based: Temperature, Light, pressor etc
  • Application Based: Automotive Sensor, Industrial Sensor etc

Lists of Different types of sensor used in electronics circuits

Different types of sensor are available some important and mostly used sensors are given below:

Name

Definition

  • Light Sensor
 Type of sensor used to Detect the light
  • Temperature Sensor
Used to measure the temperature of room or atmosphere
  • Motion Sensor
It is used to detect the movement of any live thing
  • Proximity Sensor
Detect the presence of nearby objects without any physical contact
  • IR Sensor (Infrared Sensor)
It can measure the heat of an object as well as detects the motion
  • Pressure Sensor
It is a device for pressure measurement of gases or liquids
  • Accelerometer Sensor
It is a type of sensor used to measure the acceleration exerted upon the sensor
  • Ultrasonic Sensor
ultrasonic sensors measure distance by using ultrasonic waves
  • Color Sensor
Detects the color of the material usually detects color in RBG scale.
  • Humidity Sensor
Measures and reports both moisture and air temperature
  • Tilt Sensor
Measure the tilting position with reference to gravity
  • Current Sensor
It is used to measure the current
  • Bio-Medical Sensor
Detect specific biological, chemical, or physical processes
  • GAS Sensor
Detects the presence of gases in an area
  • Speed Sensor
Measure the speed of wheels
  • Force Sensor
Use load cells to weigh objects and prevent machinery from overloading
  • Hall effect Sensor
Used to measure the magnitude of a magnetic field
  • Compass Sensor
A device whose function is to give the right directions
  • Flow Sensor
Used to control the exact dosing of gases or liquids in many technical systems
  • Level Sensor
Determining the level or amount of fluids, liquids or other substances that flow in an open or closed system
