The detection range is a function of the emitter forward current with a maximum current of 200 mA. The range is typically between one and two feet, much better than the previous generation. The user can select the resolution of the proximity sensor, either 12-bit or 16-bit. The ambient light sensor has 16-bit resolution. It is important to note that the gesture and ambient light sensing are completely independent from one another and can be measured simultaneously. The sensor is automotive qualified.
