IS31SE5001 IR SENSOR FOR TOUCHLESS PROXIMITY July 2013 GENERAL DESCRIPTION The IS31SE5001 is a low-power, reflectance-based infrared light sensor with advanced signal processing and digital output. The sensor can detect making touchless motion possible. The IS31SE5001 uses one infrared LED and an internal receiver which pick up the reflectance signal to perform touchless motion detection. When proximity motion happens, the flag bit in status register will be triggered and an interrupt signal is generated to inform the master to read the flag bit through I2C interface. IS31SE5001 is available in QFN-8 (2mm × 2mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
