ams iAQcore Indoor air quality sensor
#####################################

Overview
********

This sample application demonstrates how to use the ams iAQcore sensor to
measure CO2 equivalent and VOC. The CO2 value is a predicted value derived from
VOC. The values are fetched and printed every second.

Building and Running
********************

This sample application uses the sensor connected to the i2c stated in the
iaq_core.overlay file.
Flash the binary to a board of choice with a sensor connected.
This sample can run on every board with i2c.
For example build for a nucleo_f446re board:

.. zephyr-app-commands::
   :zephyr-app: samples/sensors/ams_iAQcore
   :board: nucleo_f446re
   :goals: build flash
   :compact:
