3pcs LD2410C Human Presence Radar Sensor Module HLK-LD2410 LD2410 Millimeter Wave Non-Contact 24GHz ISM Band Serial Port IO Level Output

Fantastic little devices!!! I've used these in combination with esp32-c3 MCUs and they perform flawlessly as presence sensors and can integrate with home assistant. Will be buying more soon!

Bought these to use as simple presence detectors with ESPHome, and they work great. Soldering the parts to a perfboard was super easy, and they are incredibly responsive. You can connect them up to Home Assistant via ESPHome, and they are incredibly useful for presence detection. Just remember to do a little fine-tuning when you get them to ensure that you get the settings right via engineering mode.

Very good in performance.

Pairs well with home assistant. Use in automation to turn on lights on and off when someone enters room. Better than IR sensors. Can detect minor movement even through furnature and walls. You can also measure distance away from sensor to detect movement entering or leaving room. Would recommend and can use with ES32 board

good product

Fun to play around with.

Amazing sensor the distance is incredible I'm definitely purchasing more. FYI this isn’t the medical heart rate tracking one.

The units arrived as advertised and all three of mine were functional, but the bag seems to be just a standard poly bag, not an anti-static mylar bag like you generally see with electronics that have a microchip in them. I saw some other reviewers comment on this as well and figured, worst case is I'd need to send them back and get a replacement, but for me, all three were in good working order and I'm going to be putting them in storage in anti-static bags. Solid LD2410C units.
