Description
The TSL2561 is an inexpensive, yet sophisticated, light sensor. Unlike simpler sensors, like photoresistors and photodiodes, the TSL2561 incorporates both infrared and visible light sensors to better approximate the response of the human eye. Because the TSL2561 is an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both very small and very large amounts of light.
