Microwave motion radar
The RCWL-0516 is particularly suitable as an alternative to using a PIR motion sensor.
When it detects a moving object, the output changes from a low logic level to a high level (3.3 volts). Appropriately interfaced (Arduino, Fishino or other), it can be used for the automatic opening of electric doors and gates, automatic lighting.
Detection range is about 9 meters.
