ALS Infrared LED Optical Proximity Detection Module TMD27713 for Arduino
The biggest advantage of this sensor is that it integrates an infrared emission tube, so there is no need of external LED support. It can determine the backlight state and ON/OFF state of touch screen during the call. In addition, this sensor has integrated the transmitter/receiver and minimizes the design. There is no space limit in design and installation, and the requirements of structural part will be relatively simple.
