IS31SE5000
IS31SE5000 is IR SENSOR manufactured by ISSI.
DESCRIPTION
The IS31SE5000 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 IS31SE5000 uses one infrared LED and 2-channel receivers which pick up the reflectance signal from the 2 photodiodes to perform touchless motion detection. When horizontal motion or proximity motion happen, the flag bits in status register will be triggered and an interrupt signal is generated to inform the master to read the flag bit through I2Cinterface.
IS31SE5000 is available in UTQFN-12 (2mm × 2mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
