Cov cuab yeej hluav taws xob hluav taws xob siv hauv kev tiv thaiv hluav taws muaj ob hom: coded thiab tsis yog -coded. Coded tswb muaj ib tug tshwj xeeb qhov chaw nyob code, tso cai rau ib tug neeg los yog ib txhij ua kom muaj zog los ntawm lub ntsiab chav tsev, thiab lub tswb sib xws yuav nyob tau yooj yim. Tsis yog- lub tswb ceeb toom tshwm sim sai li sai tau thaum muaj hluav taws xob thiab xav tau lub tswb hluav taws xob tawm tswv yim / tso tawm kom txuas mus rau lub tswb hluav taws xob. Feem ntau, ib qho module tuaj yeem siv rau kev tswj hwm kev sib koom ua ke hauv tib cheeb tsam.
Tsis tas li ntawd, cov cuab yeej ceeb toom hluav taws tuaj yeem raug faib ua ntau txoj hauv kev raws li cov qauv kev sib txawv thiab cov xwm txheej ntawm daim ntawv thov. Raws li kev tshawb nrhiav, lawv tuaj yeem muab faib ua ionization, photoelectric, thiab semiconductor hom. Photoelectric pa luam yeeb detectors yog raws li lub hauv paus ntsiab lus ntawm optical scattering thiab rhiab heev rau cov pa taws loj uas tsim los ntawm smoldering hluav taws; semiconductor pa luam yeeb detectors yog raws li cov kev hloov nyob rau hauv lub conductivity ntawm semiconductor cov ntaub ntawv thiab yog rhiab heev rau combustible gases, teb sai sai qhib nplaim taws; ionization detectors siv thaj tsam ionization tsim los ntawm cov khoom siv hluav taws xob los xyuas cov kev hloov pauv tam sim no. Raws li daim ntawv thov txoj kev, lawv tuaj yeem muab faib ua sawv ntsug- ib leeg cov pa luam yeeb thiab cov tshuab hluav taws xob tsis siv neeg sib txuas. Cov kab ke sib txuas tuaj yeem xa cov cim ceeb toom mus rau huab cov ntaub ntawv saib xyuas lub platform rau kev saib xyuas cov chaw taws teeb thiab kev sib txuas. Raws li kev ua haujlwm sib xyaw ua ke, lub tswb tuaj yeem muab faib ua ib qho khoom siv hluav taws xob thiab "peb-sensor" cov cuab yeej ntse uas suav nrog cov pa luam yeeb, qhov kub thiab txias, thiab ntsuas cov pa taws. Raws li txoj kev xa cov teeb liab, lub tswb nrov tuaj yeem muab faib ua cov xov tooj hluav taws xob thiab lub tswb wireless (xws li cov raws li Wi-Fi, NB-IoT, thiab lwm yam wireless networks).
