Car Sensor - Sensor classification

Currently there is no one on the sensor uniform classification methods, but more common are the following three ways:1, according to the physical quantity sensor classification, can be divided Car Cooling Temp Sensor, force, velocity, temperature, flow, gas composition, and other sensors 2, the principle of classification by the sensor, can be divided into resistors, capacitors, inductors, voltage, Hall, optical, grating , thermocouples and other sensors. 3, according to Car Sensors of the sensor output signal classification, can be divided into: the output switch ("1" and "0" or "on" and "off") of the switch sensor; output is an analog type sensor; output pulse or code digital sensors.
