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.
