I’m making a bunch of mmWave sensors using ESP32-C and LD2410C. I directly soldered the pins to the ESP32-C since VCC, GRD, PIn 9, and 10 as RX and TX. This makes it easier to build. I desoldered the central PIN of the LD2410C. Testing 3 of them and it’s working great after adjusting 8 zones of pow…

Hi, thank you very much for sharing your project. Could you please provide a link for the esp32 and the mmwave module? And did you connect the uart port?

Another question, did you have to connect the LD2410C via Bluetooth to set it up or is uart all you need to get it working?

Perfekt, thank you. What exactly is the Bluetooth APP for?

It’s for adjusting the power sensitivity of the mmWave for different distances both for motion and static objects.

There is a long thread with more details on the LD2410 chip if anyone is interested in more details of setting up and using the low cost mmWave sensor. [image] LD2410 esphome tips ESPHome @Wayne_Perryman If you’re using Android like me, I linked to the Android APK I sidelo…

I tried to install your libraries today, but esphome is showing errors when compiling. /data/cache/platformio/packages/toolchain-xtensa-esp32s3/bin/../lib/gcc/xtensa-esp32s3-elf/8.4.0/../../../../xtensa-esp32s3-elf/bin/ld: /data/esp32n-schlafzimmer-mmwave/.pioenvs/esp32n-schlafzimmer-mmwave/src/ld2…

Somehow my esp32 will not connect to the ld2410. All created entities are unavailable. I don’t see anything in the log either. I did what you described in your github repo. I am able to connect via the bluetooth app to the ld2410 board.

Got it working with a different esp32 board on different pins. Thanks a lot. I especially like that you implemented the light sensor. I have two problems though. The light sensor is jumping a lot within 20% at least. And I see warnings in the log: [15:03:58][W][component:204]: Component ld2410 to…

If anyone is looking to set this up with an ESP32 S2 Mini, then I’ve created a case model along with a standoff to help with soldering. I did change the YAML from SCREEK to completely disable WiFi sleep as it was causing the sensors to disconnect momentarily every few hours. https://www.printables.…

mmWave sensor with wifi for $8 (work in progress)
