UD6 Ultrasonic Movement Sensors - Indoor Vehicle Detection

The UD6 Ultrasonic Sensor activates alarm systems by sensing motion inside the vehicle interior when it's parked. Using a 40 kHz ultrasonic frequency with adjustable sensitivity, it emits inaudible sound waves that bounce off interior surfaces and return; changes in reflection indicate movement. Easy to connect, it triggers a signal via a negative output wire when motion is detected.
