Lub tshuab ntes roj plaub
1, Txheej txheem cej luam
- Nws tuaj yeem ntes tau plaub lub roj tib lub sijhawm thiab tas li: methane (CH4), oxygen (O2), carbon monoxide (CO), thiab hydrogen sulfide (H2S). Nws kuj tseem tuaj yeem ua rau lub tswb ceeb toom thaum cov roj ntau dhau qhov txwv. Lub cim tshiab muaj tus qauv tsim, uas yog ob qho tib si zoo nkauj thiab ruaj khov. Nws suav nrog cov haujlwm xws li kev hloov kho thiab calibration ntawm cov roj. Cov khoom muaj lub luag haujlwm khaws cia thiab kaw cov ntaub ntawv tsis siv neeg, uas hloov kho thiab sau dua tshiab hauv lub sijhawm tiag tiag. Lub sijhawm thiab hnub tuaj yeem teeb tsa, thiab nws raug them siv lub charger sawv ntsug, ua rau nws yooj yim thiab siv tau. Lub CD4 tshiab muaj lub tshuab ntes nrog 8-bit microcontroller ua chav tswj, siv cov khoom siv ntes tau zoo, muaj kev nkag siab siab thiab teb sai. Lub vijtsam siv cov xim siv lead ua kua ntau yam kub, uas meej thiab txhim khu kev qha. Thaum cov roj ntsuas tau ntes tau hauv ib puag ncig ncav cuag lossis ntau dua lossis poob qis dua tus nqi ceeb toom ua ntej, lub tshuab ntes tam sim ntawd tso tawm suab thiab lub teeb ceeb toom kom ceeb toom peb kom ua cov kev ntsuas kev nyab xeeb raws sijhawm kom ntseeg tau tias muaj kev nyab xeeb ntawm lub neej thiab khoom vaj khoom tsev.
