With the development of autonomous driving and new energy vehicles, the number of sensors in automobiles is exploding.

Safety Systems: Collision sensors, airbag sensors, tire pressure monitoring systems (TPMS).

Advanced Driver Assistance Systems (ADAS) and Autonomous Driving: Cameras, millimeter-wave radar, lidar (LiDAR), ultrasonic radar (for parking).

Powertrain Systems: Crankshaft position sensor, oxygen sensor, accelerator pedal position sensor (for fuel injection and emission control).

Body Control: Rain sensor (automatic wipers), light sensor (automatic headlights), seat position sensor.
