Ultrasonic Sensor CircuitElectroSchematics

The ultra sonic circuit is adjusted in such a way as to stay in balance as long the same as the output frequency of the transmitter. If there is some movement in the area covered by the ultrasonic emission the signal that is reflected back to the receiver becomes distorted and the circuit is thrown out of balance. The circuit works from 9-12 VDC and can be used with batteries or a power supply.
