What sensors are there in the car?

Sensors in automobiles include knock sensor, water temperature sensor, air temperature sensor, air flow sensor, wheel speed sensor, oxygen sensor, camshaft position sensor, crankshaft position sensor, throttle position sensor, coolant temperature sensor, abs sensor, etc. Take abs sensor as an example, it is used in the anti-lock braking system of motor vehicles. The vehicle speed is monitored by an inductive sensor. Abs sensor outputs a set of quasi-sinusoidal AC electrical signals through the interaction with the gear ring that rotates synchronously with the wheel. Frequency and amplitude are related to wheel speed, and the output signal is transmitted to abs electronic control unit to realize real-time monitoring of wheel speed.
