Description:

The GH-311 is a ultrasound motion sensor. The GH-311ultrasonic Motion sensor provides precise, non contact distance measurements from about 2 cm (0.8 inches) to 3 meters (3.3 yards). It is very easy to connect to microcontrollers such as the BASIC Stamp SX or Propeller chip,requiring only one I/O pin.
