Mikroe Proximity 14 click features the Vishay Semiconductors VCNL36825T fully integrated proximity sensor. It combines a high-power VCSEL (vertical-cavity surface-emitting laser) and a photodiode for proximity measurement and signal processing IC. The Proximity 14 Click provides proximity detection in applications with highly tight space requirements through its standard I2C bus serial digital interface. It comes with a programmable interrupt function. With a range of up to 20cm (7.9″), the VCNL36825T simplifies usage in consumer and industrial applications. There are no mechanical barriers are required to isolate the emitter from the detector optically.
