The Ultrasonic Motion Detector uses ultrasonic sound waves to detect motion. (NOT INFRARED) This emits sound waves at a frequency higher than humans are able to hear – typically in the range 30kHz to 10MHz. Transducers comprise a pair of devices, one is a transmitter and one is a receiver. A sound pulse is sent out at a given frequency and it is reflected and captured by the receiver. To use just point it at the area you wish to detect motion in. INCLUDES FREE MINI TRIPOD
