TSL2561 Luminosity & Infrared Light integrating sensor

The TSL2561 Luminosity Sensor Breakout is a sophisticated light sensor which has a flat response 

across most of the visible spectrum. Unlike simpler sensors, the TSL2561 measures both infrared 

and visible light to better approximate the response of the human eye. And because the TSL2561 is 

an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring 

both small and large amounts of light by changing the integration time.

The TSL2561 is capable of direct I2C communication and is able to conduct specific light ranges 

from 0.1 – 40k+ Lux easily. Additionally, the TSL12561 contains two integrating analog-to-digital 

converters (ADC) that integrate currents from two photodiodes, simultaneously. Each breakout requires 

a supply voltage of 3V and a low supply current max of 0.6mA.
