PIR vs Microwave Sensors: Koj xav tau dab tsi?

Cov kev xaiv yuav tsis meej pem thaum nws los xaiv qhov zoo tshaj plaws sensor rau kev ruaj ntseg ntawm koj lub tsev lossis qhov chaw ua lag luam. Passive infrared (PIR) thiab microwave sensors yog ob hom nrov sensors. Txawm tias muaj tseeb tias lawv ob leeg hnov ​​​​cov lus tsa suab, lawv ua haujlwm sib txawv thiab tsim nyog dua hauv qee qhov xwm txheej. Txhawm rau pab koj xaiv qhov raug sensor, peb yuav tshuaj xyuas qhov txawv ntawm PIR thiab microwave sensors hauv tsab ntawv no.

Kev ntsuas PIR:

PIR sensors siv kev hloov pauv hauv hluav taws xob infrared hauv ib cheeb tsam tshwj xeeb txhawm rau txheeb xyuas cov lus tsa suab. Cov sensors no muaj npe nrov rau lawv qhov tseeb thiab kev cia siab thiab feem ntau siv hauv kev ruaj ntseg hauv tsev. PIR sensors zoo meej rau kev pom cov tub sab vim lawv tuaj yeem hnov ​​​​lub cev kub.

Qhov tseeb tias PIR sensor tsis cuam tshuam los ntawm kev cuam tshuam los ntawm lwm yam khoom siv hluav taws xob yog ib qho ntawm nws cov txiaj ntsig tseem ceeb. PIR sensors muaj qee qhov kev txwv, txawm li cas los xij. Txij li thaum lawv ua haujlwm los ntawm kev hloov pauv qhov kub thiab txias, lawv tsis muaj txiaj ntsig yog tias tus neeg tawm tsam tsis txav mus. Qhov no txhais tau hais tias tus neeg nkag tebchaws uas tseem nyob lossis txav mus qeeb heev tuaj yeem tsis pom los ntawm PIR sensors.

Sensors rau microwaves:

Los ntawm kev tsim lub microwave pulses thiab soj ntsuam cov pulses 'rereflect, microwave sensors muaj peev xwm ntes tau cov lus tsa suab. Lawv feem ntau siv nyob rau hauv qhov chaw nthuav dav xws li chaw nres tsheb thiab warehouses. Microwave sensors yog qhov zoo tshaj plaws rau kev siv sab nraum zoov vim lawv tuaj yeem ntes txhua qhov kev txav, txawm tias ntawm tsheb thiab tsiaj.

Lub peev xwm ntawm microwave sensors txhawm rau txheeb xyuas kev txav mus los ntawm cov teeb meem xws li phab ntsa yog ib qho ntawm lawv cov yam ntxwv tseem ceeb. Txawm li cas los xij, piv rau PIR sensors, lawv muaj ntau dua rau cov tswb cuav. Qhov no yog vim nws lub peev xwm los ntes txhua qhov kev txav, txawm tias cov uas coj los ntawm sab nraud xws li cua thiab nag.

Qhov twg yog qhov tsim nyog rau koj?

Cov lus teb rau lo lus nug no yog nyob ntawm koj qhov xwm txheej tshwj xeeb. PIR sensor tej zaum yuav yog qhov kev xaiv zoo heev yog tias koj tab tom nrhiav rau lub sensor sab hauv tsev los siv hauv qhov chaw me me. Lawv yog qhov tseeb thiab ntseeg tau, thiab lwm yam khoom siv cuam tshuam yuav tsis cuam tshuam rau lawv. Lub microwave sensor yuav yog qhov kev xaiv zoo dua yog tias koj xav tau lub sensor rau thaj chaw loj lossis siv sab nraum zoov. Lawv muaj peev xwm dhau los ntawm phab ntsa thiab lwm yam kev cuam tshuam thiab kev nkag siab ntawm qhov deb.

Hauv kev xaus, muaj qhov zoo thiab qhov tsis zoo rau ob qho tib si PIR thiab microwave sensors. Nws yog ib qho tseem ceeb uas yuav tau coj koj cov kev xav tau tshwj xeeb rau hauv tus account ua ntej xaiv qhov kev xaiv. Yog tias koj tsis paub meej, tham nrog tus kws kho mob tshwj xeeb. Lawv tuaj yeem muab cov lus qhia paub zoo rau koj uas koj xav tau los xaiv qhov zoo tshaj plaws sensor rau koj cov kev xav tau.
