Best budget light sensor
We bought a bulk pack for our makerspace workshops. Every single unit worked out of the box. The dynamic range is impressive for such a cheap component.

Perfect for my smart home project
This sensor works flawlessly with my Arduino Uno. The I2C connection was easy to set up, and the readings are consistent with my standalone lux meter. Great value for the price.

Good accuracy, simple wiring
I used this for a solar tracking robot. It responds quickly to changes in light intensity. The only downside is that the pin headers were not included, so I had to solder them myself.

Solid choice for university projects
Used this for my final year embedded systems project. Documentation online is plentiful which helped a lot. Deducting one star because the PCB silk screen is a bit faint.

Reliable and compact
Small form factor makes it easy to integrate into tight spaces. The library support for ESP32 is excellent. Highly recommended for beginners and pros alike.

Great for monitoring plant light
I installed three of these in my greenhouse to monitor light levels for different plants. They have been running stable for months without any drift in data.
Q: Can this sensor measure UV index?
A: No, the BH1750FVI chip measures visible light illuminance in Lux. It is not designed to measure UV radiation or provide a UV index reading.
Q: Are there sample libraries available for Raspberry Pi?
A: Yes, there are several Python libraries available for Raspberry Pi, such as 'bh1750' via pip. You can also find C++ examples in the official Raspberry Pi documentation forums.
Q: Does this come with pre-soldered headers?
A: No, this module is typically shipped without pre-soldered pin headers to allow for flexible mounting options. You will need to solder your own headers or wires.
Q: What is the maximum distance for the I2C connection?
A: For reliable communication, we recommend keeping the I2C cable length under 30cm (12 inches). If you need longer distances, please use an I2C extender or buffer.
Q: Is this module compatible with 5V logic levels?
A: Yes, the GY-302 module operates on a voltage range of 3.3V to 5V, making it fully compatible with both 3.3V and 5V microcontrollers like Arduino Uno and ESP8266.
