The future development trend of automotive sensor

technology is miniaturization, multi-functional, integrated and intelligent.Late 20th century, design technology, materials technology, especially Mems (micro electro mechanical systems) technology to make micro-sensor raised to a new level, the use of Crank Position Sensor to micron level sensor, signal processors, data processing device package on the same chip, it has a small, inexpensive, high reliability, and can significantly improve system testing accuracy. Mems technology can produce a test using mechanical quantity, the amount of magnetic, thermal capacity, chemical and biomass miniature sensors. As Mems tiny sensors in automotive electronic systems reduce costs and improve its performance advantages, they have begun to gradually replace traditional electromechani Engine Coolant Temperature Sensor. Mems Sensor will become the world's major automotive electronics components.
