Example code does not compile, gives out of range error when you try to implement the HIGH_RES_CONTINUOUS_MODE_2. Works correctly with default value for resolution.

i.e. modifying the lightMeter.begin() line to
lightMeter.begin(BH1750::CONTINUOUS_HIGH_RES_MODE_2). (tried it with and without the :: and using the underscore _ instead, as shown in the table of commands. Neither would compile and produced an out of range error.

Not very sensitive when using the “light ball” version. Apparently the white ball (plastic hemisphere) attenuates the ambient light severely. I thought it would be much more transparent, and thus much more sensitive to ambient light.

Direct, very bright Braun white multi LED flashlight only a few inches away, (far brighter than sunlight), only gives about 600 lux, thus not using most of the dynamic range of the sensor, and reduced accuracy as a result, for solar light monitoring.

In reply to Jhon Kitri Sianturi. With the NodeMCU, I get "Device not Configured". How do I fix that, please?

Hi.
Yes. It is the same.

Stupid question perhaps.
But is IIC the same as I2c ?

Greetings bert

Hello all, I want to ask, I have a problem when I use the sensor module bh1750 and ESP32. Where on the Arduino IDE serial monitor there is a message like the following “Device is not configured! Light: -2.00 lx”. When I searched for the solution to the problem, it was at the following link https://github.com/claws/BH1750/issues/36 and other links. With NodeMCU, the bh1750 sensor module can measure light intensity, whereas when I use the ESP32, the BH1750 sensor module can’t measure. Can anyone give a solution? #ask

Please make a video on the lilly go TTGO esp32 with the sim7600. Posting data to the cloud the sim800 one only supports 2g network
