Presence detection with LD2410 and BH1750 - i2c doesnt work

Moet · October 28, 2024, 5:14pm

Hi,
I am trying to set up a motion detection based on a D1 mini with a LD2410 and a BH1750 sensor. The LD2410 is connected via the uArt port and the BH1750 should work with the i2c.

This is my config:

on my D1 mini I have the LD2410 connected like this:
D1 mini ↔ sensor
RX<->TX (with RX on the D1 beeing GPIO3)
TX<->RX (with TX on the D1 beeing GPIO1)
5V<->VCC
GND<->GND

on my D1 mini I have the BH1750 connected like this:
D1 mini ↔ sensor
D1<->SCL (with D1 on the D1 beeing GPIO5)
D2<->SDA (with D2 on the D1 beeing GPIO4)
3V3<->VCC
GND<->GND

i cant get the BH1750 to work. I already tried 3 different sensors. This is what the log says:

So it basically looks like the i2c can’t find any devices.
I tried connecting the BH1750 by itself without the rest of the code like:

captive_portal:

i2c:
  sda: GPIO4
  scl: GPIO5
  scan: true
  id: bus_a

sensor:
  - platform: bh1750
    name: "Illuminance"
    address: 0x23
    update_interval: 15s

and it works without any issue.

So what is my mistake? Does UArt and i2c dont work together? Do any ports double?

Could anyone hint me in the right direction?

Thank you in advance!

regards,
Markus

Hi Markus,

You may be better off using an esp32 to capture motion, i2s, and uart serial data. The little 8266 in the D1 mini might not be keeping up.
You will also have more pins available and less chance of the board wanting to re-use pins or something. (and more memory for the firmware)

tmo · October 28, 2024, 9:31pm

Your sensor definition is missing i2c_id: bus_a.

Moet · October 30, 2024, 11:18am

Thanks for the response

sensor:
  - platform: bh1750
    name: "Illuminance"
    address: 0x23
    update_interval: 15s
    i2c_id: bus_a

unfortunatly the same error occurs

Moet · October 30, 2024, 11:18am

i will try that, thank you.

tmo · October 30, 2024, 12:06pm

I don’t think so. There is a little bit UART going on, and a little bit I2C, nothing that would make an ESP8266 sweat. The problem seems to be that there are no i2c devices found on the bus.

Since the i2c scan doesn’t find any device, there might be issues with your wiring. Maybe SCL/SDA swapped?
Maybe pullup resistors missing?
What happens when you increase the i2c frequency (100, 200, 400kHz)?

Moet · October 30, 2024, 12:57pm

Nope, checked and rechecked it alot of times… even rewired it “wrong” to check…

I tried 100, 200 and 400kHz with no change.

What do you mean by that?

In the meantime i did wire up a esp32 and pasted in the same code, changing board and i2c pins and it works…

Maybe it is an issue of the d1_mini or the esp8266 by itself …

Thank you for your help! Using the smaler d1_mini would be nice as a smaler “housing” would be possible.

tmo · October 30, 2024, 4:37pm

OK, seems you tried already a lot

Since I am interested in motion detection anyways, but don’t have a motion sensor yet, I’ll order one now. Either I find a solution, or I will know that an ESP8266 is not enough for this combination of sensors.

Just to get a comparable setup on my side: which LD2410 exactly do you have? AFAIK there are several versions out there.

Moet · November 1, 2024, 12:36pm

i have the LD2410C
