Based on the TSL25911 technology, this high-sensitivity digital ambient light sensor module has a 600M:1 wide dynamic range, can detect light intensity up to 88000Lux, is controlled via an I2C interface, and uses little power. It can function in a variety of lighting conditions.

Waveshare offers a digital light intensity sensor. The TSL25911 chip, on which the module is based, allows for the detection of light intensities up to 88000 lx. There has a 600M:1 dynamic range. It connects to the main module via an I2C interface and works with both Arduino and Raspberry Pi. It uses less electricity and is employed in a variety of lighting situations.

The TSL2591 is a very sensitive light-to-digital converter that converts light intensity into an output digital signal that may be directly interfaced with an I/C device. One CMOS integrated circuit is used in the device to house one broadband photodiode (visible and infrared) and one infrared-responding photodiode. The photodiode currents are converted by two integrating ADCs, into a digital output that shows the measurement of irradiance for every channel. This digital output can be fed into a microcontroller, which will use an empirical formula to determine the ambient light intensity in lux, or close to the reaction of the human eye. A conventional level style interrupt is supported by the TSL2591 and is asserted until the firmware clears it.


  • Measures visible and infrared light (wider range than TSL2561), adopting TSL25911FN.
  • Direct light intensity signal output to the I2C interface, embedded ADC, and reduced noise jamming
  • Broad dynamic range up to 600M:1 and high sensitivity up to 188uLux
  • Precise measurement is possible even in environments with high infrared noise thanks to an embedded infrared-responding photodiode.
  • offers adjustable upper and lower thresholds for interrupt output.
  • 3V/5V operational voltage compatibility for the onboard voltage translator
  • includes a handbook and development materials (examples for Raspberry Pi, Arduino, and STM32).
