AirGradient Open Source Air Quality Monitor for CO2 and PM2.5 Measurements
Open source diy is wonderful. But is there a reliable trustworthy monitor that can just... Be bought? A box that will reliably tell me what's the carbon dioxide carbon monoxide dust allergens volatile compounds? Am I possibly being greedy and I need several konitors (I wouldn't have an issue with that)?<p>Every review I check for any consumer accessible device seems to indicate they're inaccurate, miscalibrated, or downright deceptive :-(
