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 the ambient environment and transfers it over to the I2C bus. Description The device features advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS), Color Sense (RGBC), and optical pattern generation/transmission for broadcast. The slim modular package, 2.36 mm × 3.95 mm × 1.36 mm, incorporates an IR LED and factory calibrated LED driver.
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 has 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.
