Okay for learning

Documentation was sparse, had to search online for code examples. Sensor works fine though.

Reliable sensor

Used it for a smart lamp project. I2C address is easy to configure if you need multiple units.

Great accuracy

Compared with a professional lux meter, readings are very close. Fast shipping too.

5 FAQ

Q: What is the default I2C address?

A: The default address is 0x23, but it can be changed to 0x5C via the ADDR pin.

Q: Does this work with 5V logic levels?

A: Yes, the module supports operating voltages from 3.3V to 5V DC.

Q: Is a library available for Arduino?

A: Yes, there are many open-source Arduino libraries available that support the BH1750.

Q: How many wires are needed for connection?

A: You need 4 wires: VCC, GND, SCL (Clock), and SDA (Data).

Q: Can it measure direct sunlight?

A: It measures up to 65535 Lux. Direct sunlight may saturate the sensor depending on conditions.
