The Best DIY Human Presence Sensor?

During months and months, I have been trying to install an LD2410B Kit, watching all the tutorials available on this subject, including yours. I failed and failed. I finally bought the LD2410"C" model and it worked magically. Thank you 1.000 times! And keep posting your videos.

Beautiful. Magnificent. Прекрасно. I`ve struggled a bit, but found this,edited the code a little bit. And there is no more suffering. Благодарско и напред.

Hi Kiril, I just ordered some of these sensors. I will use it for the lamps. Thank you for the video!

Thanks. I may order this board and try this out. 👍🏻

Thanks Kiril. Very nice video!

Do you like the soldering iron? I'm almost buying a weller, but I'm looking for a more inexpensive alternative that works the same. It has to work good as a weller does

Hello Kiryu, I want to tell you that you are one of the main reasons that I moved from Hubitat to HA and I am so happy even if it needs a lot of learning so thank you! very much.

Could the ESP32 not only connect the LD2410 (wired) but also be a bluetooth proxy for other LD2410 around the house? Also I think you should make a video on how to best power these devices... it's simple enough to use a USB cable but maybe there's a great/cheap way to have these setup around the house without using up 1 socket with an unsightly cable...

I have bought two LD2410C boards to detect when someone is on the stairs in my house. I'll then set up lighting with WLED. Because the stairs go round two 90 degree turns I decided to put one sensor at the top and one at the bottom. I'm assuming they'll each need a ESP32 board to complete this setup. Great video - thank you for all the useful information!

Professionally for Small store automation... Ring if no one is in the store area and someones enters... small neighbourhood shops... personally for light control in certain areas of my house...

Been using mine LD2410C for about a week now. For now been just playing with it and getting to the point where I just got it perfect tooned in. For my first automation I've just made a simple one, When I sit down on my office chair, it will turn off the ceiling light and turn on a smaller wifi lamp. When ever it will sense presence in my pc chair the light will stay on and when I go to the sofa (mainly when I want to watch some movies) it will turn that lamp off. My objective is, when I build in my new desk the sensor will turn on the LEDs that I will be installing on the setup, and every time I leave the setup they will turn off.

I am using the same yaml file as your example. But it would not work on my esp32 wroom dev board. After searching around a bit I found that under the uart setting you have to put the GPIO for RX pin and GPIO for TX pin. Just thought I would pass it along. Great Video Keep Up The Good Work..... uart: id: ld2410_uart tx_pin: GPIO1 rx_pin: GPIO3 baud_rate: 256000 parity: NONE stop_bits: 1

I Just created a digital clock and message board using a 8x32 LED matrix. It's all Home Assistant driven. My plan was to integrate the LD2410 sensor in the clock to just display the time/date/temperature when somebody is detected in front of the clock. I have that now working with a Shelly Motion sensor, that triggers a Tuya USB Smart switch that powers the D1 Mini running WLED and the Matrix board. If I can put the LD2410 sensor on another ESP board with relay, I can use that to enable/disable power to the WLED

There's an esphome PR 4434 that vastly improves LD2410 sensors in esphome which will hopefully be merged soon. It allows configuring all the thresholds in homeassistant rather than having to have them statically in the yaml.

Hi Kiryl! I tried to use YAML that was mentioned in your article but failed now matter how many times I tried. ESPHome advised to use Numbers in the code, in the ESPHome documentation they show the sample. Could you please advise how to combine the whole code with Numbers. Thank you!

I was wondering if it was possible to create the sensor using esp01 instead of esp32. so as to make it more complicated? Thank you

I bought some of the Bluetooth ones a while back and tried them with the HA's Bluetooth interface but couldn't get them going. Realised a bit later that the metal case of the pi was probably blocking it. When I put the module closer to the pi it worked fine, but not much good if all the sensors have to be within a short distance from the pi. Going to give this a try with the remaining modules to see if I can spread them around the house a bit.

Hi. Great video. Really enjoying your explanations. Are there any comparisons of the features that are different vs an FP2? I’m fine with the diy difference (and cost). How about the ability to define zones with a single sensor? Thanks!

Hello Kiryu, I created a smart led staircase. All steps have a WS2811 LED strip attached and I use 4 radars. 1 radar on top and 1 on bottom, and 1 radar going down, 1 radar going up from the middle because I have an entrance in my house from the middle. Middle sensors act as boolean to avoid triggering the top and bottom radars. I used 2 ESP32 to which I attached 1 x LD2410 + 1 x LD1125H

Hi Kiryu, the issue with LD2410 (B/C version) over Bluetooth was that it sends a ton of data over that interface and BT link drops. There was no way to limit amount of data that is been sent. Moving to tx/rx interface and using wifi to connect to HA, this issue might be closed. Can you share your experience on how much data is been sent to HA with config that you described? Is this adustable via ESPHome config - like having 5 second for timeout?
