Working Principle
Detection
detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physical motion information to a digital information.
Proximity Detection
The proximity detection features provides object detection by photodiode detection of reflected IR energy(Sourced by the integrated LED).
Digital Ambient Light Sense & Color Sense
The Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the R, G, B, C channels have a UV and IR blocking filter and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to accurately measure ambient light and sense color which enables devices to calculate illuminance and color temperature, control display backlight, and chromaticity.
