Open Type Ultrasonic Sensor
Summary
Principle of ultrasonic sensor: When alternating electrical signal is transferred to the sensor, the sensor will emit an ultrasonic signal. The signal in the air will be reflected to the sensor when it encounters an obstacle. The sensor has a large measuring range and strong anti-interference, mainly used for rear passenger monitoring system (ROA system) and anti-theft alarm device, etc.
