TheoryofOperation

TheCO2sensorinsidethisdeviceusesnon‐dispersiveinfraredtechnologytosense,asafunctionof

transmittedlight,theconcentrationofCO2intheair.Ithasbeenfactory‐calibratedtooperatewithin

thespecifiedrangeandprecision.

0‐1%and0‐30%UnitsOnly

Thesensorusesanalgorithm

calledAutomaticBackgroundCalibration(ABC)tocontinuouslyadjustthe

zero‐pointtoensureaccuracyismaintained.Thisisrequiredtocompensateforsensordrift,which

occursnormallyontheseunits.Theprimarycontributortosensordriftisthenormalandunavoidable

agingoftheinfraredlightsourcewithinthesensor.

TheABCalgorithmallowstheCO2sensortodynamicallyshiftitsCO2readingbyaconstant.Itworksvia

storingthelowestCO2sampletakenovertheABCperiodandassumingthatthislowvalueisequaltoa

knownvalue(thetargetva lue). Itthenadjuststheoutputofthe

CO2readingbythedeltabetween

thesevalues.Thisalgorithmdoesnotaffectthelinearizationoftheoutputsignal.

Forexample,theABCalgorithmisenabledbydefault,withanABCperiodof180hours,atargetvalueof

400ppm,andamaximumdelta of30ppm.Thisoperatesunderthe

principlethataCO2 levelinambient

outdoorairis400ppm.

ThesensorwillkeeptrackofthelowestCO2readingrecordedoveraperiodof180hoursandthen

adjustthezeropointbasedonthelowestCO2levelrecorded,upto30ppmatatime,towardsthat

value.
