Hi-Link HLK-LD2411S 24GHz Radar Sensor Module met Bluetooth

This sensor serves as a replacement for a PIR sensor and works based on microwaves and the Doppler effect. This sensor can detect movement due to a difference in speed, which also works through almost all materials except metal. The sensor data can be read out via the UART interface or via a Bluetooth connection in combination with the HLKRadarTool app on Android/iOS.

No cable is included, but it can be bought separately: Molex Picoblade Female to DuPont Female Compatible Cable - 5p
Note: The colors of the cable do not logically correspond to those of the sensor.

Note: The sensor has an OUT pin, however, it has no function.
