  "description": "Built around the ams-OSRAM TMD3725, the Sense.ACP provides digital ambient light sensing (ALS), RGBC+IR color measurement with 16-bit data converters, and IR-based proximity detection with an integrated LED and factory-calibrated driver. Color photodiodes include UV and IR blocking filters while ALS gain is adjustable from 1× to 128× for operation across a wide range of lighting conditions. Proximity detection is interrupt-driven with configurable thresholds, offset compensation, and automatic ambient light subtraction.  An on-board 3.3V buck converter supplies the IR LED driver from the V+ input.",
