According to the role of the sensor, it can be classified into sensors that measure temperature, pressure, flow rate, position, gas concentration, speed, brightness, dry humidity, distance and other functions.
They each perform their own duties. once a sensor fails, the corresponding device will work abnormal or even not work. Therefore, the role of sensors in the car is very important.
Car sensors, once used solely for engines, are now being used in chassis, body and lighting electrical systems. These systems use more than 100 sensors.
Among the various kinds of sensors, the common ones are:
