Proximity 7 click 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 an 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 a firmware optimization.
With its ability to accommodate to different light conditions especially behind dark glass, the ADPS9930 represents an ideal solution for dimming TFT and LCD displays on various devices. Positioned behind a semi-transparent bezel, it can still detect proximity and ambient light amount, regulating the brightness of the screen, accordingly, saving a lot of power that way. The ADPS9930 IC has a very low power consumption itself, that can be further optimized.
The Proximity 7 click is a perfect choice for a range of applications that rely on the proximity and ambient light sensing (ALS), including:
- PC and laptop monitors
- POS displays
- embedded displays
- proximity-activated short-range security, etc.
