HLK-LD2410B Human Presence Radar Module Sensor Heartbeat Detection Smart Sensor Kit
A part of the review has been auto-translated.
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.
Perfect
Just put this into my PC ; the proprietary android app is necessary, it wont pair with phone / PC - however the module is amazing, the tiny board is the actual radar with the host doing bluetooth
Detects human presence from 5 meters away.
Your website shows it is delivered but I have not yet received
Ok
