Great device! Monitors both CO2 and air pollution levels. Only missing feature is the ability to monitor outdoor CO2 on a map like air pollution can be tracked. This would be helpful scientific data to have to help track climate change.
While this device only checks outdoor Air Quality from IQ Air sensors, it turns out that we have 3 sensors in town, and one is just a few blocks away! It's good to see the prediction for future air quality, it reminds us if we should close up the windows overnight.
Nice little device. In the summer, when the doors and windows are open, it measures the particulate level. In the winter when things are shut up tighter than a drum, it will be far more helpful.
