Cov pa roj carbon monoxide (CO) yog roj txaus ntshai heev, vim nws tsis hnov tsw, tsis tau saj. Koj tsis tuaj yeem pom nws, lossis kuaj pom koj lub qhov ntswg. Kuv lub hom phiaj yog tsim cov ntsuas CO yooj yim. Ua ntej tshaj plaws, Kuv pom cov pa me me hauv kuv lub tsev. Qhov ntawd yog qhov laj thawj, vim li cas kuv thiaj tsis suav ppm (rau qhov me me ntawm CO, koj xav tau lub ntsuas pom tseeb heev + ntsuas kub thiab av noo tau cuam tshuam rau kev ntsuas).

Nov yog kuv cov vis dis aus, koj tuaj yeem siv ENGLISH SUBTITLES.

Hauv kuv qhov kev sib tham, Wemos D1 so haujlwm yog siv los ntawm lub adapter, uas suav 1.5 W los ntawm lub qhov (socket). Tsis tas li ntawd, kuv ntsuas tam sim no siv roj sensor, uas yog cca 100 mA

Koj xav tau tus neeg hais lus tus account thiab hauv tus thawj tswj tsev qiv ntawv hauv Arduine IDE Wemod D1 (so haujlwm) board. Qhov no yog tus lej.

Ib qho teeb meem yog suav qhov tsis kam ntawm cov pa roj (Rs), uas tsis raug (Kuv tau txais cov mis los ntawm lub vev xaib sab nraud). Koj yuav tsum paub tus nqi ntawm kev kho qhov ntsuas.

Ntawm no koj tuaj yeem pom qhov ntsuas qhov ntsuas thiab qhov hluav taws xob tso tawm ntawm kuv lub sensor.

Nov yog kab lus qhia yuav ua li cas xam ppm -> hais txog ib lab ntawm ib tus neeg ntawm cov pa.

Ua ntej tshaj, koj yuav tsum paub R0, uas yog qhov tsis kam ntawm lub ntsuas cua ntawm huab cua ntshiab nrog 1000 ppm ntawm hydrogen. Koj tuaj yeem sau nws li R0 = Rs ntawm huab cua ntshiab.

Qhov thib ob, koj yuav tsum paub Rs, uas yog qhov tsis kam ntawm lub ntsuas qhov twg yog CO roj ntawm qee qhov kev xav.
