What is Sensor and types of sensor

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 sensor

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
