Reliable and easy to code
Integrated this into an autonomous robot for light-seeking behavior. The library support for Arduino is abundant, making integration very quick. Highly recommended for beginners and pros alike.

Good sensor, needs pull-up resistors
The module itself is excellent and accurate. Just remember that you might need external pull-up resistors on the SDA and SCL lines depending on your microcontroller board. Once sorted, it works great.

Works well for plant monitoring
Using it to monitor sunlight exposure for my indoor garden. It handles the range well from dim indoor light to bright window sunlight. Deducted one star only because the pin headers were not soldered.

Simple and effective
As someone new to electronics, I found this very easy to set up. Plenty of tutorials online specifically for the GY-302. It lit up my LED strip based on room brightness exactly as planned.

Great for university projects
Bought this for a final year project on smart lighting systems. It provides precise data and the form factor is small enough to fit inside our custom enclosure easily.

Perfect for my weather station project
This sensor works flawlessly with my ESP32. The I2C communication is stable, and the lux readings are consistent with my handheld light meter. Great value for the price.
Q: Is the pin header pre-soldered to the board?
A: Typically, these modules are shipped with the pin header strip included but not soldered, allowing you to choose between straight or right-angle mounting. Please check your specific package contents upon arrival.
Q: Does this module work directly with 5V Arduino Uno without a logic level converter?
A: Yes, the GY-302 module typically includes a voltage regulator and can operate safely between 3.3V and 5V, making it directly compatible with the Arduino Uno.
Q: How fast is the sampling rate?
A: The conversion time depends on the resolution mode selected. In high-resolution mode, it takes approximately 120ms per measurement, while low-resolution modes are faster at around 16ms to 24ms.
Q: What is the default I2C address for this sensor?
A: The default I2C address for the BH1750FVI sensor on this module is usually 0x23. However, some variations allow changing the address to 0x5C by modifying the ADDR pin connection.
Q: Can this sensor measure UV index?
A: No, the BH1750FVI measures visible light intensity in Lux. It is not designed to measure UV radiation or provide a UV index reading.
