Automotive sensors - temperature sensors inside it is a semiconductor thermistor, the lower the temperature, the greater the resistance; on the contrary, the smaller the resistance of automotive sensors which, installed in the engine block or cylinder head put water, cooling water directly contact. Whereby the side of the engine cooling water temperature is obtained. Electronic control unit according to the change of the measured engine coolant temperature sensor wholesale car, the lower the temperature, the greater the resistance; on the contrary, the smaller the resistance. The electronic control unit according to the measured change in the temperature of the engine cooling water, as a fuel injection and ignition timing of the revision number. That we can understand the state of the car is now running car engine water temperature sensor by stopping or sports car sensor identification, or sports such as how long. There are three commonly used classification: ⒈ by physical classification of the sensor can be divided into displacement, force, velocity, temperature, flow, gas composition and other sensors ⒉ sensor works by classification, can be divided into resistors, capacitors, inductors, voltage, Hall, optoelectronics, grating, thermocouples, and other sensors. ⒊ by the nature 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 sensor; output pulse or code The digital sensor.
