Abstract
The ambient illuminance sensor system disclosed herein includes a light sensor to generate a series of ambient illuminance values from an area surrounding a computing device, a human presence sensor configured to detect presence of a human in vicinity of the computing device, and computer implemented instructions for determining ambient illuminance level (AIL) based on at least in part on the series of ambient illuminance values, determining presence of a human in vicinity of the light sensor, and based on at least in part on determining that the AIL is below a threshold and that a human is present, applying a hysteresis filter to process the series of ambient illuminance values.
