Infrared proximity sensor Si11xx series

rectangulardigital

Silicon Labs' optical sensor family enables sensing UV Index, ambient light, long range proximity, heart rate/pulse oximetry and motion with 2D or 3D gestures. Si114x, Si1132, Si1120 and Si1102 sensors are the industrys most sensitive active infrared proximity sensor ICs. They offer excellent performance under a wide variety of light sources including direct sunlight and under dark glass. The photodiode response and associated digital conversion circuitry deliver excellent immunity to artificial light flicker noise and natural light flutter noise.
