The ultrasonic radar circuit's design is reasonable,and it has been several field trials,and it works reliably. The circuit is sealed by the ultrasonic sensor R/S40 (including transmit and receive), the signal receiving and processing control circuit, alarm, display circuit and power supply etc., and the circuit is shown in photo. Each part of the circuit is described below. The ultrasonic sensor R/S40 in the circuit is not only used for transmitting ultrasound, but also receiving the reflected echo, so it has a two-way transmit / receive function.
