TSL2561 Digital Luminosity/Lux/Light Sensor Breakout

The TSL2561 is a light-to-digital converter that translates light intensity into a digital signal output I2C. Sensitive to visible light and infrared for a near-optical response with a dynamic range of 20 bits. Two integrated ADCs convert the photodiodes' currents into a digital output, which measures the light intensity of each channel.
