Ultrasonic transceiver circuit that shares transducer (Tx & Rx)

Jester · Jul 10, 2015

Does anyone have a link to a tried and true 40kHz transducer circuit that uses only one transducer, switching back and forth from Tx mode to Rx mode?

You are wiser to use 2 transducers in simplex mode that try to share 1 in half-duplex mode due to wide dynamic range disparity in power levels at transition time.
