Proximity 5 click 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 analog 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 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.

Proximity 6 click is a versatile proximity detection device on a Click board™. It can detect a foreign object distanced up to 20cm. The Click board™ features a detection sensor IC that can trigger a threshold based interrupts, which makes this Click board™ capable of detecting even simple gesture movements. The advanced onboard IC sensor features LED driver section, a light sensor with the integrated analog front end (AFE), 14 bit analog to digital converter (ADC), and digital engine for processing and aggregation of the measurement result, which simplifies the firmware development. The ambient light cancellation includes both digital and optical filtering, resulting in increased detection reliability.
