Ultrasonic Sensor
A sensor using sound waves to detect nearby obstacles.
Ultrasonic sensors assist parking and low-speed maneuvering by emitting high-frequency sound waves. They measure echo time to determine distance. Dirt or damage can reduce sensitivity. Cleaning sensors regularly ensures consistent operation. They're simple, low-cost, and reliable for close-range detection. Commonly found in bumpers for parking assist and automatic braking.
