If have foreign object, causing the wave to get back, there is a chang and The control system is running, this circuit can be detected, both indoors and outdoors. The circuit works from 9-12 VDC and can be used with batteries or a power supply. These ultrasonic sensors work with high frequency that more than a human ear can hear. Unlike audio frequencies which are between 20Hz and 20kHz, ultrasonic-frequency are greater than 20kHz and into the hundreds kilo-Hertz and even MHz.Common ultrasonic amplifier applications are piezo transducer and sensor. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages.
