Keyestudio ALS Infrared LED Optical Proximity Detection Module TMD27713 for Arduino

It is a triple sensor integrated with ambient light,proximity sensor and infrared LED, which has two functions,for one thing, it is used to detect the current ambient brightness (ALS); It can in accordance with the current ambient brightness automatically adjust the backlight brightness to conform to ambient light by the mean of software adjustment,which can make backlight brightness soft to protect your vision and to achieve the effect of energy saving.For another feature we are referred to as proximity sensor function (PROX). Sensor has been integrated transmitter/receiver and minimized the design, besides, design and installation have no more space restrictions, and for part of a structure is relatively simple.
