Why Does Accuracy Matter So Much with an Ambient Light Sensor? (.PDF Download)

    Dec. 11, 2015

    The purpose of an ambient light sensor (ALS) is to allow electronic systems to “see” light like a human eye. The spectrum of the human eye is called the photoptic response. Matching the photopic response as closely as possible will improve the human-machine interaction, extend the life of the system, and improve system power utilization...
