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 ninja flash
device is 0x20001a08, name is IAQ_CORE Co2: 882.000000ppm; VOC: 244.000000ppb Co2: 863.000000ppm; VOC: 239.000000ppb Co2: 836.000000ppm; VOC: 232.000000ppb
