Small Air Sensors

Small and inexpensive community sensors are here to stay. They can provide improved spatial coverage of an air monitoring network, but the accuracy of the data results in limited usefulness.

Laboratory and field testing has shown sensors to have manufacturing biases, interferences from temperature and humidity, and errors in translating measured voltages or particle counts to regular engineering units (ppb, ug/m3, etc.). They are not quantitative, and in many cases they are barely considered qualitative. To be useful, meaningful data, any correction also needs to be applied in real-time.

To be useful even as a qualitative instrument, some correction must be applied to the instruments. Sometimes that correction can be in the form of a simple calibration curve (mX+b) or polynomial correction derived by collocation of the instrument with a field NAAQS or other high-accuracy monitor.
