I deleted two of your messages, it looked like something went wrong
But like i said, just exchange the BH1750 for a different one, that will probably fix it.

Already changed the BH1750 to one other , but still this low lux measurement'sThinkPad wrote:I deleted two of your messages, it looked like something went wrong![]()

Then i would say: check the wiring (connected to analog pin instead of digital pin by accident)? Or maybe the sketch has changed and some calculation is different... Try with a BH1750 example sketch to see what readings you get.
It should definately read more than 72 lux, my Aeon multisensor tops out at 1k lux at day, it sits in my livingroom with no direct sunlight at it.

I already checked the wiring 10times and already changed this to eliminate that.
I soldered the wires direct on the arduino instead of using the breadboard debont wires

If you measure today the weather is that bad that the lux is very low (maybe that's all:-) )

Didn't put it on the window indeed, just inside with lights on. Still, I think that 19 lux is too low. What were your readings today?

Mine was around 800 during mid-day, and around 200 lux when it started to get a bit dark (~16:30).
Sensor is working really good in my situation. Faced south, behind matte window foil.
I wish i could help, but i already mentioned the things you could try (check pinout, change sensor etc).

Re: BH1750 lux sensor: reading 54612 lux???
Unfortunately today I had the same issue.
However before re-flashing the sensor was working perfectly.
With that in mind I tried several different BH1750 libraries that I could find on the web and finally found one that worked.
So instead of the sensor being broken.. an 'incompatible' library can also cause problems.
From now on I keep the library with the sketch.
