Working principle:

Gesture Detection

Gesture detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physical motion information to digital information.

Proximity Detection

The proximity detection features provide 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 provide 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 colour which enables devices to calculate illuminance and colour temperature, control display backlight, and chromaticity.
