Ultrasonic Distance Sensor (2-500cm)

For use with the Sensor Master. Able to detect changes in distance from the sensor - e.g. when somebody walks in front of it. 

This is an ultrasonic sensor with an open dual-probe, employing standard interface of Gravity PH2.0-3P vertical patch socket. 

The sensor comes with built-in temperature compensation, which can greatly reduce measurement error caused by over high/low temperature. It adopts analog voltage output, and provides accurate distance measurement within 2-500cm with 1cm resolution and ±1% accuracy. The design of dual probe effectively decreases the dead zone. Users can check the measurement process conveniently by the onboard indicator.
