Good value, small footprint
Great little module for the price. It fits perfectly in tight enclosures. Only giving 4 stars because the pin headers were not included, but that's a minor issue.

Reliable outdoor use
Using this inside a waterproof case to monitor sunlight for my garden irrigation system. It has been running for three months without failure. Solid build quality.

Great for learning I2C
Bought this for a university project. Documentation online is plentiful, and it connected to my Raspberry Pi without any driver issues. Very satisfied.

Easy to integrate
As a beginner, I was worried about wiring this up, but the labels on the PCB are clear. Plenty of tutorials available. Works great right out of the box.

Accurate and fast response
I needed a sensor that reacts quickly to light changes for an automatic lighting project. The BH1750FVI chip on this board delivers exactly that. Highly recommended.

Perfect for my weather station
This sensor works flawlessly with my Arduino setup. The readings are consistent and match my standalone lux meter very closely. Setup was easy using standard libraries.
Q: Does this module work with 5V logic levels directly?
A: Yes, the GY-30 module includes a voltage regulator and level shifting, so it is safe to use with both 3.3V and 5V microcontrollers like Arduino Uno.
Q: Is there a library available for ESP32?
A: Yes, there are several open-source libraries compatible with the ESP32 ecosystem. You can search for 'BH1750' in the Arduino Library Manager which supports ESP32.
Q: What is the maximum cable length for I2C connection?
A: For reliable I2C communication, we recommend keeping cable lengths under 30cm. For longer distances, you may need an I2C extender or buffer.
Q: Can this sensor measure UV index?
A: No, the BH1750FVI chip is designed to measure illuminance in Lux (visible light) and does not specifically measure UV radiation or provide a UV index.
Q: What is the default I2C address for this sensor?
A: The default I2C address is typically 0x23. Some variations might use 0x5C depending on the ADDR pin configuration, but 0x23 is the standard for most GY-30 boards.
