Here we come to know about the main sensor on the car. Air flow sensor is the sucked air into electrical signals supplied to the electronic control unit (ECU), as one of the signals determines the basic fuel injection. According to the measuring principle different quality auto level sensor can be divided into rotary wings air flow sensor, Karman vortex air flow sensor tours, hot air flow sensor and the hot film air flow sensor four types. The first two for both volume flow type, after the mass flow type. The main use of hot air flow sensor and two kinds of hot-film air flow sensor. Automotive Sensor - speed sensor speed sensor is more important electric vehicle level sensor sensor car manufacturers, but also more sensor applications. By definition car water level sensor, the speed sensor is used to measure the speed of the main sensor, divided into speed sensor, vehicle speed sensor, wheel speed sensors. Speed ??sensor is mainly used for electric vehicle motor rotation speed detection. There are three commonly used speed sensor automotive wholesale level sensor, respectively, electromagnetic induction type speed sensor, speed sensor photoelectric sensors, Hall-effect speed sensors are non-contact measuring principle, in order to enhance detection of security, improve the detection accuracy .
