the 1.27mm converter looks great, did you manufacture it by your self or is there a online store that sell them?

@DariBer Designed by me, manufactured by JLCPCB… Let me check how many I still have.

44

Thanx!

Let me know and I’ll pay for them and shipping.
Or if you sent to share the files and I can order from some company that manufactures PCB

Hi,

great project do you have an English version of the Datasheet with the serial Protocol?

Many thanks!

English Version seems to be available… I checked it in the Apple AppStore and I downloaded the App and the first Screens are now in English… Unfortunately my Sensor has not arrived so I cannot test the App to conform that all Screens are now translated…

Here is the IOS-App: ‎HLKRadarTool on the App Store

Do you mind sharing a link to it?

For what? What link you need?

@crlogic …

One Question to your Code: Will it support the two Values from the Sensor:

  • Stationary Presence
  • Moving Object

This will help a lot for Automation within HA… Could you give some Details about it?

My solution with JST 1.25mm connector.

Nice idee, using the JST 1.25 connector.
I ordered 2 LD2410 sensors from the Shenzhen Hi-Link Electronic co.,Ltd Store on Ali and received the LD2410B Bluetooth version. Now i have connected the sensor just by it’s output pin (no serial) as i am only interested in the ‘Presence’, not any distances. Added the sensor to my Ikea Vindriktning hack…
Configuring the sensor using the IOS app (already in English) is easy.
I had some trouble to find the pinout, so:

Has anyone tested the LD2410 power consumption?

I got some 1.27 headers and this adapter but the JST cable is much simpler.

I wonder how difficult would it be to support the Bluetooth version via the Bluetooth integration and Bluetooth proxy

Sorry if I have missed any post or so. But if using the YAML and the uart_read_line_sensor_ld2410v3.h code/file above, to what pins do I connect to a ESP32 or D1 mini board if using same colors as on the photo
