The Proximity 7 Click Board™ is advanced proximity and ambient light sensing Click Board™. It features the ADPS9930, a digital sensor IC equipped with two photodiodes (PD) and an IR LED, driven by a proprietary LED driver circuit. It allows accurate proximity detection for a maximum distance of 100mm. The proprietary LED current driving technique eliminates the need for calibration, simplifying the design. A huge dynamic range allows ambient light sensing closely matched to the response of the human eye, in a variety of light conditions. An extensive interrupt engine allows for firmware optimisation.
