The Proximity 5 Click Board™ is a very accurate and reliable proximity sensing (PS) and ambient light sensing (ALS) device, equipped with the state-of-the-art PS and ALS sensor. The signal processing and conditioning section, three IR LED drivers, and the low noise analogue front end with the PS and ALS photo-sensitive elements, are all integrated into the sensor IC, ensuring very accurate and reliable readings, while reducing the workload of the host MCU.
The proprietary Filtron technology provides near-human eye light spectrum sensitivity and a top-class background light cancellation scheme for the ALS section, additionally reducing the workload of the MCU. Finally, the programmable interrupt engine reduces the MCU workload, even more, saving the host MCU of constant polling of the sensor for data.
