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.
