Color/proximity sensor P12347-01CT Color sensor, proximity sensor, and 3-color LED incorporated into a single package This is a multifunctional sensor that incorporates a color sensor, proximity sensor, and 3-color LED in a small package (5.5 1.7 1.0 mm). It can be used to adjust the display image quality, perform touchscreen on/off control, indicate incoming calls, and so forth on smartphones and the like. The color sensor not only detects the RGB ratios of ambient light but also functions as an illuminance sensor. This feature enables image quality to be adjusted in ne detail. In smartphone applications, the proximity sensor detects when a face draws near and turns off the touchscreen function and the LCD backlight. We provide an evaluation kit for this product as well as an evaluation board. Contact us for detailed information.
