Exactly as described
Fast shipping and the module arrived well-packaged. The chip is clearly labeled as original BH1750FVI. Readings are linear and reliable across different lighting conditions.

Good value, accurate enough
Using this to monitor sunlight in my greenhouse. It's not laboratory grade, but for the price, it provides consistent data for triggering my irrigation system.

Integrates well with ESPHome
Connected directly to my ESP32 running ESPHome. No calibration needed out of the box. It accurately detects when room lights are turned on or off.

Perfect for my smart lamp project
This sensor works flawlessly with my Arduino Uno. The readings are stable and match my handheld lux meter very closely. The included cable made wiring a breeze.

Great for learning I2C
Bought this for a university electronics course. The library support is excellent, and I got it up and running in under 10 minutes. Highly recommended for beginners.

Solid performance
The build quality is decent. The soldering points are clear. Only minor issue is the cable is a bit short for some of my enclosures, but easy to extend.
Q: How do I change the measurement resolution?
A: The resolution can be changed via software commands sent over the I2C bus. The datasheet provides specific hex codes to switch between High, Low, and Auto-resolution modes.
Q: Can this sensor measure UV index?
A: No, the BH1750FVI is designed specifically to measure visible light intensity (Lux) and mimics human eye sensitivity. It does not measure UV radiation.
Q: What is the maximum distance the cable can be extended?
A: While the included cable is 20cm, you can extend the I2C lines. However, for reliable communication without signal degradation, we recommend keeping total cable length under 1 meter unless using shielded cables or pull-up resistor adjustments.
Q: Does this module work with 5V logic levels directly?
A: Yes, the module operates on a voltage range of 3.3V to 5V, so it is fully compatible with 5V microcontrollers like the Arduino Uno without needing a level shifter.
Q: Is there a library available for Python on Raspberry Pi?
A: Absolutely. There are several open-source Python libraries available for the BH1750 on GitHub that work perfectly with Raspberry Pi GPIO pins.
