VCNL4100

VCNL4100 is a high sensitivity long distance proximity and ambient light sensor with I²C interface. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip using a CMOS process. The 16bit high resolution ALS offers excellent sensing capabilities with sufficient selections to fulfil most applications whether a dark or high transparency lens design. It offers individual programmable high and low threshold interrupt features for the best utilization of resources and power saving on the microcontroller. For the 8bit proximity sensing function, it has a built-in intelligent cancellation scheme that eliminates background light issues. Application includes presence detection to activate displays in printers, copiers, and home appliances, collision detection in robots and toys, proximity sensing and lighting control in offices, corridors and public buildings, vehicle occupancy detection in parking lots, proximity detection in lavatory appliances.
