Wireless Motion detector

The Wireless Motion Detector W36 is a sonar device that emits ultrasonic pulses, which reflect off an object. The sensor measures the time it takes an ultrasonic pulse to travel from the sensor to the object and determines the distance from the object based on the measured time and the speed of sound. The minimum range of the sensor is 0.15 m and the maximum range is 6 m.
The sensor can be used wirelessly via Bluetooth or wired via USB.
The sensor is equipped with an OLED color display which shows some sensor information and the measured by the sensor values. This makes the sensor suitable to use as an independent measuring instrument.

Technical specifications of the sensor are descibed it its User's guide.
