Description

The Doppler Radar Sensor Module - RCWL-0516 is a doppler radar microwave sensor module for detecting moving objects. This can act as an alternative to Passive Infrared (PIR) motion sensing. The RCWL-0516 sensor detects "any movement" from "any object" and does not rely on heat, making it more reliable in hot environments.

Unlike the PIR sensor, this is an active sensor. Active sensors send out a pulse of energy and detect the changes in the return signal, while passive sensors detect energy emitted or reflected from an object.

This product come with headers already soldered on.
