Misleading and confusing
The 2nd edition is just off all charts: 5° Temperature difference, 7% Humidity difference, 10x PM difference, 7x Chemical difference. If temperature and humidity are so way apart, how about the other sensors? First device tells me its polluted, second one shows no pollution. What's the trick?
