Lub hauv paus ntsiab lus thiab muaj pes tsawg leeg ntawm lub sensor

Lub sensor yog cov cuab yeej tshawb nrhiav, lub cuab yeej rau kev tau txais cov ntaub ntawv, lossis lub tshuab xa cov kev xav. Hauv cov ntsiab lus dav dav, lub sensor yog lub cuab yeej, module, lossis subsystem, feem ntau siv hauv kev tswj tsis siv neeg thiab ntsuas tshuab. Lub sensor tuaj yeem txhais tau tias yog lub cuab yeej lossis cov cuab yeej uas tuaj yeem hloov pauv qhov ntsuas lub cev (xws li ceev, kub, suab, lub teeb, thiab lwm yam) mus rau lwm qhov ntau ntawm lub cev (feem ntau yog hluav taws xob) uas yooj yim rau kev sib kis thiab ua haujlwm.
Lwm txoj hauv kev los faib cov sensors yog los ntawm hom kev tso tawm lawv tsim, raws li seb lawv puas yog analog lossis digital. Analog sensors hloov ib puag ncig inputs mus rau qhov sib txawv ntawm cov zis analog teeb liab.
Tsis zoo li analog sensors, digital sensors hloov ib puag ncig inputs rau hauv discrete digital signals kis nyob rau hauv binary hom (1s thiab 0s). Digital sensors tau dhau los ua ntau yam thoob plaws txhua qhov kev lag luam, hloov cov analog sensors hauv ntau qhov xwm txheej. Piv txwv li, digital sensors tam sim no siv los ntsuas cov av noo, qhov kub thiab txias, barometric siab, huab cua zoo, thiab ntau lwm yam kev tshwm sim ib puag ncig.
Cov yam ntxwv ntawm cov sensors muaj xws li: miniaturization, digitization, txawj ntse, multi-function, systemization, thiab networking. Nws yog thawj qhov txuas kom paub txog kev tshawb nrhiav tsis siv neeg thiab tswj tsis siv neeg. Lub hav zoov thiab kev loj hlob ntawm cov sensors tso cai rau cov khoom muaj kev xav xws li kov, saj, thiab tsw, thiab ua kom cov khoom muaj sia nyob maj mam. Feem ntau raws li nws cov kev paub yooj yim, nws tuaj yeem muab faib ua kaum pawg: thermal sensor, lub teeb sensor, roj sensor, quab yuam sensor, sib nqus sensor, av noo sensor, suab sensor, hluav taws xob sensor, xim sensor thiab saj sensor.
