ARDUINO M719 Face detection close distance illumination sensor module TMD27713 Electronic Components Electronic Hobby Kit

Module chip: TMD27713. Detection distance 100mm.Ambient light + proximity sensor + infrared LED triple sensor TMD2771X used in mobile phones mainly serves two functions:One function is used to detect the current ambient light brightness (ALS); and the software adjusts the backlight brightness automatically according to the current ambient light brightness conditions to adapt to the ambient brightness; the backlight brightness is soft to protect the eyesight Achieve the effect of saving electricity .Another function, we call the Proximity Sensing function (PROX) uses the internal LED to emit infrared reflections and sensor built-in PD to determine whether the phone is close to the human face during the call, to determine the backlight status and touch-screen button status is ON /OFF.
