APDS-9999中文资料Digital Proximity and RGB Sensor数据手册Broadcom规格书

描述 Description

APDS-9999 is a digital I2C compatible interface RGB and proximity sensor with VCSEL in a single 6-pin package. The device uses four individual channels of red, green, blue, and IR in a specially designed matrix arrangement. This allows the device to have optimal angular response and accurate RGB spectral response with high Lux accuracy over various light sources. The device detects light intensity under a variety of lighting conditions and through a variety of attenuation materials, including dark glass. The device could be configured as ambient light sensor (ALS) and RGB sensor. The proximity detection feature operates well from bright sunlight to dark rooms. The addition of the micro-optics lenses within the module provide highly efficient transmission and reception of infrared energy which lowers overall power dissipation. In addition, the device can be put into a low-power standby mode providing very low average power consumption.
