It is the Bluetooth version (but the silkscreen on PCB mentions LD2410 without the B). For Android, use app from the Play store (HLKRadarTool). UART is connected to the USB. Has 2 LEDs: red power LED and green LED when person is detected. IMPORTANT: Does not work with USB-C/USB-C cable or charger. It has USB-C port, but does not support USB PD, so the charger (or port on laptop) won't provide any voltage and it will not power on. You must use USB-A / USB-C cable.

Well constructed radar module to detect presence. Better than IR ones that could be affected by thermal variations. I haven't tested yet if my module has Bluetooth capability.

Q:
Does the larger board do anything other than host the sensor and link to a proprietary Android app? I ask because the Bluetooth range and human detection range appear to be similar, so it's not adding a great deal!

A:

The large board seems to be mostly a breakout board with voltage regulator, usb-c port and presumably a usb communication chip to interface with the radar chip.

Is it really HLK-LD2410B (bluetooth version)? Because the one I received has just HLK-LD2410 on silkscreen on the bottom of the module (the small board)
