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.
