Hi-Link HLK-LD2410S 24GHz Radar Sensor Module - 3.3V - Low Power

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. This sensor from the Hi-Link HLK-LD2410 series is optimized for low power consumption, which makes it better suited for battery use. The sensor status can be read via the "OT2" pin or via the UART interface.

Note: This version of the HLK-2410 series does not have Bluetooth and has a different UART protocol.
