WH77140UC Datasheet | Unknown Manufacturer

WH77140UC Digital Ambient Light Sensor and Proximity Sensor Description The WH77140UC is a light to digital converter which bines an advanced ambient light sensor, an advanced proximity sensor and a high efficiency infra light LED. The pitch of sensor and LED is only 1.45mm, so it is suitable for small IR hole design. Ambient light sensor (ALS) built-in an optical filter for IR rejection, and providing a spectrum which is close to the human eye’s response. ALS can work from dark to direct sunlight, the selectable detect range is about 40dB. ALS has excellent light ratio under different light conditions. Proximity sensor (PS) built-in an 940nm optical filter for ambient light immunity,...
