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.
