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 automotive sensors, installed in the water, put the engine block or cylinder head, in direct contact with cooling water. Whereby the side of the engine cooling water temperature is obtained. The electronic control unit according to the measured change in the temperature of the engine cooling water, the lower the temperature, the greater the resistance; contrary resistance smaller. Electronic control unit according to the change of the measured temperature of the engine coolant automotive sensors which, as a fuel injection and ignition timing correction number. That we can understand the state of the car is now running through the engine water temperature sensor stops or how much money a sports car, or the movement, such as how long. Future trends in the automotive sensor technology is miniaturization, multi-functional, integrated and intelligent. The late 20th century, the design technology, materials technology, particularly the development of Mems (microelectromechanical systems) technology makes miniature sensors raised to a new level, the use of MEMS processing technology will micron level sensor, signal processors, data processing device package on the same chip, it has a small, cheap, high reliability, and can significantly improve the accuracy of the system test. Mems technology can detect the use of mechanical quantities produced, the amount of magnetic, thermal capacity, chemical and biomass miniature sensors. Because Mems miniature sensors in automotive electronic systems to reduce costs and improve its performance advantages, they have begun to gradually replace the traditional electromechanical sensor based technology. Mems sensors will become an important component of the world's automotive electronics.
