Ambient Light Sensor

Digilent offers its PmodALS which features a 3-wire SPI™ communication interface

The Digilent PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. Digilent engineers designed this Pmod around Texas Instruments' ADC081S021 analog-to-digital converter and Vishay Semiconductor's TEMT6000X01. The PmodALS utilizes a single ambient light sensor (ALS) for user input. The amount of light the ALS is exposed to determines the voltage level passed into the ADC, which converts it to 8-bits of data. A value of 0 indicates a low light level and a value of 255 indicates a high light level.
