Sensor classification

At present, there is no unified classification method for sensors, but the following three types are commonly used:

1. According to the physical quantity of the sensor, it can be divided into sensors such as displacement, force, speed, temperature, flow, and gas composition.

2. According to the working principle of the sensor, can be divided into resistance, capacitance, inductance, voltage, Hall, photoelectric, grating thermocouple and other sensors.

3. According to the nature of the sensor output signal, it can be divided into: switch type sensor whose output is switch quantity (“1″ and “0″ or “on” and “off”); the output is analog type sensor; the output is pulse or the digital sensor of the code.
