The TSL2591 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from 188 uLux up to 88,000 Lux on the fly.


  • Approximates Human eye Response
  • This board/chip uses I2C 7-bit address 0x29 and 0x28 (Both)


A detailed tutorial showing how to wire up the sensor, use it with an Arduino and example code that gets readings and calculates lux.
