Good but needs pull-ups
Sensor works well but remember to enable internal pull-ups on I2C lines if your board lacks them.

Small form factor fits easily into my robot chassis. Consistent data output over time.
Q: Does this work with 5V logic levels?
A: Yes, the module supports 3.3V to 5V input voltage and logic levels.
Q: What is the default I2C address?
A: The default address is usually 0x23, but some variants may use 0x5C depending on the ADDR pin.
Q: Can I use this sensor outdoors?
A: It is not waterproof. Please enclose it in a protective case for outdoor use.
Q: Which library should I use for Arduino?
A: We recommend the standard BH1750 library available in the Arduino IDE Library Manager.
Q: Does it come with header pins?
A: Yes, a set of header pins is included in the package for soldering.
