This sensitive ultrasonic motion detector circuit uses a quartz crystal to lock the detector frequency for maximum stability and reliability.
All components, including the Xtal controlled oscillator, detector circuits and a pair of edge mounted ultrasonic transducers, are mounted on a single board. Only the power supply (PP3 battery clip provided) and Signal Out connections are required.
Detects motion up to 4-7m away. Sensitivity is adjustable. Red LED 'active' indicator. Signal Output (8.5Vdc) is capable of driving an external relay (e.g. Order Code 1168) or other low power circuit. Designed for indoor use.Specifications
