Overview
Proximity 9 Click_ 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 IRED emitter, along with the low noise analog 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 response near to the human eye spectral response, providing the background light cancellation. The programmable interrupt engine allows for the development of an optimized firmware, reducing the MCU workload and power consumption.

Proximity 9 Click
Requirements
This shield can only be used with a board that provides a mikroBUS™ socket and defines a
mikrobus_i2c node label for the mikroBUS™ I2C interface. See :ref:shields for more
details.
Programming
Set -DSHIELD=mikroe_proximity_9_click when you invoke west build. For example:
.. zephyr-app-commands:: :zephyr-app: samples/sensor/proximity_polling :board: mikroe_clicker_ra4m1 :shield: mikroe_proximity_9_click :goals: build
See :dtcompatible:vishay,vcnl4040 for documentation on the additional binding properties available
for the VCNL4040 sensor.
