What is sensor , tpyes of sensor

Hello friends ...

I hope you all are Safe . Today we are discuss about electrical sensors. so let's see

You know human have so many sensor in Human body ..like that

1) eyes for sense the vision

2) ears for sense hearing

3)nose for sense smell

4)skin for sense touch

5)tongue for test..

so friends above the example we define the sensor definition

what is the sensor

A sensor is a equipment (device) that detect the many types input from physical environments like

Temperature, light, volume, material (objects), speed, moisture, motion, pressure, flow etc..etc..

What is Electrical sensors..?

A sensor is a device that detect the physical changes environment Temperature, light, volume, material (objects), speed, moisture, motion, pressure, flow etc..etc.. and convert in to Electrical signals or feedback

Types of sensor

1)Digital Sensors (PNP AND NPN )

digital sensor is an electronic or electrochemical sensor, where data is digitally converted and transmitted and given feedback 0v or 24vdc

LIST OF DIGITAL SENSOR

Proximity sensor

1) Inductive Proximity for sense the metal object

2) Capacitive Proximity for sense metallic or non-metallic object

3) photoelectrical proximity

4) Ultrasonic proximity

Pressure switch - measure the pressure of liquids ,gas or any Air
flow switch - measure the flow of liquid
photo electric sensor ( diffuse types , retro reflector , transmitter - receiver )
Water Quality measure sensor (ph meter )
IR sensor
level sensor
Motion Sensor
