The Grove - Light & Color & proximity sensor is TMG39931 based product, which features advanced detection, Proximity detection, Digital Ambient Light Sense(ALS), Color Sense(RGBC), and optical pattern generation/transmission for broadcast. This four-in-one sensor allows you to collect the data from ambient environmet and ntransfers over the I2C bus.
detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physical motion information to a digital information.
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.
