Great for learning I2C
As a student, this was the perfect component to learn how I2C protocols work. The documentation online is plentiful, and the module is very forgiving with wiring mistakes.

Works well outdoors in enclosure
Using this to monitor sunlight for my automated greenhouse. It needs a waterproof enclosure, but the sensor itself handles the temperature variations well. Readings are stable.

Plug and play with libraries
Downloaded the standard BH1750 library, uploaded the sample code, and had data on the serial monitor in minutes. No calibration needed for general purposes. Excellent product.

Reliable and accurate
I bought five of these for a robotics competition. All units performed identically. The spectral response really does mimic human vision well, making it great for automatic lighting control.

Good value, easy to solder
The pins were not pre-soldered, which was fine for me, but beginners might need help. Once connected, the library examples worked immediately. Great accuracy for the price.

Perfect for my smart home project
This sensor works flawlessly with my Arduino Uno. The I2C communication is stable, and the lux readings are consistent with my professional light meter. Highly recommended for beginners.
Q: Does this sensor work in complete darkness?
A: Yes, the sensor can detect very low light levels down to 1 Lux. In complete darkness, it will return a value near zero, though absolute zero may vary slightly due to noise.
Q: What is the maximum distance for the I2C connection?
A: For reliable I2C communication, we recommend keeping the cable length under 30cm (12 inches). For longer distances, you may need an I2C extender or buffer.
Q: Is there a specific Arduino library required?
A: While you can write your own driver, we recommend using the widely available 'BH1750' library by clavika or similar variants found in the Arduino Library Manager for ease of use.
Q: Can I use this with a 3.3V microcontroller like ESP32?
A: Yes, the BH1750FVI operates within a voltage range of 3.3V to 5V, making it fully compatible with 3.3V logic systems like the ESP32 and Raspberry Pi.
Q: Does this module come with headers pre-soldered?
A: No, this module typically comes with unsoldered pin headers to allow for flexible mounting options. You will need to solder them yourself or use jumper wires directly.
