RCWL-0516 microwave sensor module - radar.

Working voltage: 4 - 28V. It provides a convenient 3.3V output to drive a microcontroller.

The forward side of the microwave sensor module is the side with the components. This side should face the objects being detected. Do not obstruct the forward side with anything metallic. The back side should have a clearance of more than 1cm from any metal.
