Optical Sensor IC Devices

Silicon Labs' optical sensor family enables sensing of UV Index, ambient light, long range proximity, heart rate/pulse oximetry and motion with 2D or 3D gestures. For standalone proximity detection applications where an analog output is required, the Si1120 and Si1102 operate without the need for an I2C interface.
