ams iAQcore Indoor air quality sensor


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:

# On Linux/macOS
cd $ZEPHYR_BASE/samples/sensors/ams_iAQcore
mkdir build && cd build
# On Windows
cd %ZEPHYR_BASE%\samples\sensors\ams_iAQcore
mkdir build & cd build
cmake -GNinja -DBOARD=nucleo_f446re ..
ninja flash
