3. Distance/Proximity sensor Application:
Distance/Proximity sensor is one of the applications of ultrasound in air. By acting both as transmitter and receiver, a piezoelectric ceramic disk transmits a short burst of ultrasonic wave to the target and receives the reflected echo from it. Distance of the object is calculated using the time difference between the received and the transmitted signal
Piezoceramic transducers for the transmitting and receiving of ultrasonic signal needed for distance measurement.
