Ld2410C Sensor Module Human Presence Radar Millimeter Wave Non Contact 24Ghz Ism Band Serial Port Io Level Output

This device does exactly what it claims. The HLK LD2410C is an extremely sensitive motion and presence sensor, and it integrates very well with Home Assistant. Once it is set up, the only real limit is your imagination for automations. If you need reliable presence detection in an area, this module is a great fit. It can detect someone whether they are sitting, standing, moving, or even staying mostly still. For my use case, it consistently “sees” a person in the space and reacts quickly. I would buy these again for any project where accurate occupancy and presence detection matters.

Litterly my favorite sensor in my kit it is perfect and it has bluetooth this module has WORK put into it fuctions perfectly

I love this little radar, I used it with a esp32 c3 and home assistant together with esphome

It's incredible how reachable some technologies become with the time. I am using it along an esp8266 wemos mini so it add presence capabilities to my home assistant setup. I created 2 automations, one to turn the living room lights on when I enter to my home, and other to turn them off later in case the dogs trigger it by accident. Planning on adding another to tell me if somebody enters the home while I am not on site, it's almost a custom alarm system for just a few dollars. Anyone who uses home assistant should give it a try.

Very Impressive, I only purchased one just to testing therefore this looks really good. Must have more. I don't have any photos yet but we will revisit.
