The TSL25911 ambient light sensor board is a compact board that sense light intensity. The board is based on TSL25911 module which is a highly sensitive light-to-digital converter that transforms light intensity into a digital signal. The board provides digital ambient light sensing (ALS) that approximates human eye response to light intensity. It enables accurate ALS measurements when exposed to very low light such as when operating behind light-attenuating materials. It provides accurate ALS measurements across a wide range of light intensities due to its ultra-high sensitivity, wide dynamic range, and ability to operate in bright sunlight.

Features
