HLK-LD2450 : 24Ghz one-transmitter-two-receiver human motion tracking trajectory radar module Wall mounted installation

Product Features

24 GHz ISM band Integrated intelligent millimeter wave radar chip and intelligent algorithm firmware Precise motion target localization and tracking Longest detection range 6m Ultra-small module size: 15mm x 44mm Wall mounting Azimuth angle ±60°, pitch angle ±35° The ultimate cost-effective choice

Multiple connection options with pin and socket interface

Product Overview

Motion target tracking is to track the position of the moving target in the region in real time, and realize the distance, angle and speed measurement of the moving target in the region.The LD2450 is a motion target tracking sensor module from the Hi-link 24G millimetre wave radar series, which includes extremely simplified 24 GHz radar sensor hardware and intelligent algorithm firmware. The solution is mainly used in general indoor scenarios such as homes, offices and hotels to enable the location tracking of moving human bodies. The sensor hardware consists of an AloT millimetre wave radar chip, a high performance one-transmitter-two-receiver microstrip antenna and a low cost MCU and peripheral auxiliary circuitry. The intelligent algorithm firmware uses FMCW waveforms and the radar chip's proprietary advanced signal processing technology. It supports serial output of detection data, which is plug-and-play and can be flexibly applied to different smart scenarios and end products.

Looks like a very interesting senor. Hope to see what can be done with it. May be similar to the Aqara FP2

There are two extant projects which seem to provide a promising starting point: the Screek human sensor 2A configuration, which is a YAML file with a lot of code in lambdas, and tsunglung's ld2450 custom component, which relegates a lot of the serial-port processing to a custom component but which still relies on a medium-messy lambda in the YAML. Neither are exactly a drop-in ld2450: component which painlessly provides a bunch of sensors but both have the back end talking-to-an-LD2450 aspect figured out.

Hi, how does it look, is there any plan to add it to ESPHome codebase?

I recently purchased the Everything Presence Lite which features this sensor. The default configuration comes with a large lambda parsing lines from serial. I just found out that amcfague is working on proper support in esphome/esphome#5624. Thank you Andrew, keep up the good work!

Thanks for update, that sounds great!

It looks like official support will be added with this pull, but it is taking months :(

Does this FR need to stay open?
