1) Gas sensor module integrates sensors thiab processing circuits, ntawm nws tus kheej thiab ua tiav tag nrho cov ntaub ntawv kev khiav hauj lwm thiab teeb liab hloov dua siab tshiab ntawm cov roj detector. Qhov tshwj xeeb cua sov ua haujlwm nthuav dav qhov ntsuas kub qis ua haujlwm ntawm lub tshuab ntes; Gas leak detector module yog lub luag haujlwm rau kev siv hluav taws xob, kev sib txuas lus, thiab cov khoom tso tawm;
2) Nws muaj lub tshuab hluav taws xob tsis siv neeg tiv thaiv kev ua haujlwm rau cov roj sensor module thaum muaj roj ntau tshaj qhov txwv. Nws pib tshawb pom ntawm lub sijhawm ntawm 30 vib nas this kom txog thaum lub concentration yog ib txwm muaj thiab lub zog rov qab los tiv thaiv cov pa roj ntau los ntawm dej nyab thiab txo cov kev pab cuam lub neej ntawm lub sensor;
3) Cov txheej txheem digital interfaces yog siv los ntawm cov qauv, thiab cov pins kub plated uas tiv thaiv kev sib tsoo yog yooj yim rau ntawm qhov chaw kub pauv thiab hloov pauv;
4) Kev hloov pauv hloov tau yooj yim thiab sib xyaw ua ke ntawm ntau lub tshuab ntsuas roj thiab ntau hom sensor modules tuaj yeem tsim ntau yam khoom siv nrog cov khoom tso tawm tshwj xeeb thiab cov khoom tshawb pom, sai sai raws li cov neeg siv khoom xav tau;
5) Kev sib xyaw ua ke yooj yim thiab ntau hom tso zis
Ntau lub tshuab kuaj pom thiab ntau hom sensor modules tuaj yeem ua ke yooj yim los tsim cov khoom ntes nrog cov khoom siv tshwj xeeb thiab siv tau rau cov hom phiaj sib txawv kom tau raws li cov neeg siv khoom xav tau;
6) Hloov lub sensor kom yooj yim li hloov lub teeb
Sensor modules rau cov roj sib txawv thiab ntau yam tuaj yeem hloov tau dawb. Tsis tas yuav calibration tom qab hloov. Ntawd yog, tus ntes tuaj yeem nyeem cov ntaub ntawv qub ntawm lub Hoobkas thiab ua haujlwm tam sim ntawd. Nyob rau hauv no txoj kev, cov khoom muaj ib tug ntev kev pab cuam lub neej. Meanwhile, nrhiav kom tau calibration tuaj yeem ua tau yooj yim ntawm qhov chaw sib txawv, zam cov txheej txheem dismantling nyuaj thiab nyuaj rau ntawm qhov chaw calibration thiab txo cov nqi kho tom qab.
