I recently bought a sensor that detects temp, humidity, PM2.5, PM10, and CO2, and the variance from the equivalent report from the airport's weather station that's only a few minutes away is discouraging even when it's set outdoors. Maybe I should bring it into my alma mater and borrow some lab equipment and test it out.
At least the CO2 says 410 when set outdoors, but the temperature it varies by a few degrees (Celcius). The humidity is even worse, I don't even bother looking at that number anymore.
The sensors I bought from Microcenter were garbage in the ways you describe. I couldn’t even take readings from some sensors because they were so ridiculous.
