Works but needs patience
Took some time to get the I2C address right. Documentation link was broken but found info elsewhere.

Reliable Module
Bought five for a lighting control system. All five worked immediately out of the box.

Highly Accurate
Compared this against a professional lux meter and it was surprisingly close. Great for the price.

Good value sensor
Accurate enough for home automation. Wish the pins were soldered differently but easy to fix.
Q: Which library should I use?
A: We recommend the popular BH1750 library available in the Arduino Library Manager.
Q: Is this 5V compatible?
A: Yes, it works with both 3.3V and 5V logic levels.
Q: Does it measure UV light?
A: No, this sensor measures visible light intensity in Lux only.
Q: Can I use this outdoors?
A: It is not waterproof. You must house it in a weatherproof enclosure for outdoor use.
Q: What is the default I2C address?
A: The default address is typically 0x23, but some variants may use 0x5C.
