Let's Control It

Hello,

I have connect a lux-sensor BH1750. The only value thats shown is 54627.50. It doesn't matter if its in a dark box or in bright light. What have I done wrong?

Hi!

I had this similar problem on one of those.
The value is max on the sensor and is either caused by wrong wiring or poor soldering.
It is very sensitive to alteration once started so you should be 100% sure everything is correct HW-wise and then reboot the ESP.

Thanks! That was the solution!

First, I resoldered the pins, then I had always 15 of intensity. Then I checked it with a microscope and found, that the sensor looked very dirty, maybe not cleaned well after soldering in the production. I wiped it softly and now it seems to work. At least I get different values.

Many thanks!
