Typical Applications
The 48kHz ultrasonic transducer can be utilized in reversing collision radar systems to enhance vehicle safety. In this application, the transducer emits ultrasonic waves that travel and bounce back upon encountering obstacles. The time taken for the echoes to return is calculated, allowing the system to determine the distance to potential hazards, significantly assisting drivers during reversing maneuvers and reducing accident risks.
