Types of sensors
A sensor is a device that responds to any change in physical phenomena or environmental variables like heat, pressure, humidity, movement etc. This change affects the physical, chemical or electromagnetic properties of the sensors which is further processed to a more usable and readable form. Sensor is the heart of a measurement system. It is the first element that comes in contact with environmental variables to generate an output.
According to the working principle of the sensor, we can divide the sensors into many types, such as photoelectric sensor, charge sensors, potential type sensor, semiconductor sensor, the electricity sensor, magnetic sensor, resonant sensor, electric chemical formula sensor etc.
Common sensor type:
Weighing sensors, resistance strain sensors, photoelectric sensors, frequency conversion power sensors, piezoresistive sensors, thermal resistance sensor, laser sensor, Hall sensor, temperature sensor, intelligent sensor, photosensitive sensor, visual sensors, displacement sensors, grating sensors, infrared sensors, vacuum sensors, pressure sensors, conductivity sensor, antimony electrode, acidity sensor, capacitive level sensor
