Excellent sensitivity range
The ability to measure from 1 to over 60,000 lux is impressive for such a small board. It handles both dim indoor lighting and bright sunlight without saturating immediately.

Solid build quality
We bought ten of these for our workshop. Most work perfectly out of the box. One had a slightly loose pin header, but nothing a little solder couldn't fix. Good bulk purchase.

Perfect for Arduino projects
This sensor works flawlessly with my Arduino Uno. The included code made setup incredibly easy, and the readings are consistent with my professional light meter. Highly recommended for beginners.

Great value, accurate enough
For the price, you cannot beat this module. It is not laboratory grade, but for a line-following robot that avoids dark areas, it is more than sufficient. I2C wiring is simple.

Works well with ESP32
I integrated this into my ESP32 home automation system to control lights based on ambient brightness. The response time is quick and the library support is excellent.
Q: What is the default I2C address for this sensor?
A: The default I2C address is typically 0x23. However, some variations allow changing the address to 0x5C by modifying the ADDR pin connection.
Q: How fast can this sensor take readings?
A: The measurement time depends on the resolution mode selected. In low resolution mode, it takes approximately 16ms, while high resolution modes take between 120ms and 180ms.
Q: Is this sensor waterproof for outdoor use?
A: No, the bare PCB module is not waterproof. If you plan to use it outdoors, you must enclose it in a weatherproof case with a transparent window for the sensor.
Q: Does this module come with the necessary library for Arduino IDE?
A: Yes, the product listing includes a link to download the compatible Arduino library and example sketch code to get you started immediately.
Q: Can I connect this directly to a 5V Raspberry Pi GPIO?
A: While the module operates on 5V, the Raspberry Pi GPIO pins are 3.3V logic. We recommend using a logic level converter for the SDA and SCL lines to ensure safe communication.
