Works but needs pull-up resistors
Had some noise on the I2C line until I added external pull-up resistors. Might be my setup, but worth noting.

Accurate Lux Readings
Compared this against a professional lux meter and the values were very close. Excellent value for the price.

Perfect for Arduino Projects
Works flawlessly with the standard BH1750 library. Readings are consistent and stable. Great for my smart home light automation.

Good sensor, minor wiring confusion
The sensor itself is accurate. I wished the pinout was printed larger on the board. Once wired correctly, it works great.
Q: Is there a library available for Arduino?
A: Yes, several libraries exist. Search for BH1750 in the Arduino Library Manager.
Q: Is this identical to the GY-30?
A: It is compatible and functionally similar, using the same BH1750FVI chip.
Q: What is the default I2C address?
A: The default address is typically 0x23, but some variants may use 0x5C.
Q: Can this be used outdoors?
A: The module itself is not waterproof. You need to house it in a weatherproof enclosure for outdoor use.
Q: Does this work with 5V logic?
A: Yes, the module supports 3.3V to 5V input voltage.
