Proximity 9 Click Board

The Proximity 9 Click Board™ is a very accurate and reliable proximity sensing (PS) and ambient light sensing (ALS) device, equipped with the VCNL4040, an integrated PS and ALS sensor which features the Filtron™ technology. The 940nm infrared emitter, along with the low noise analogue front end, and the PS/ALS photo-sensitive elements, is integrated on the VCNL4040 IC, ensuring very accurate and reliable measurements. The proprietary Filtron™ technology provides a response near to the human eye spectral response, providing the background light cancellation. The programmable interrupt engine allows for the development of an optimised firmware, reducing the MCU workload and power consumption.
