Sensor (Lus Askiv lub npe: transducer / sensor) yog cov cuab yeej tshawb nrhiav uas tuaj yeem nkag siab cov ntaub ntawv ntsuas, thiab tuaj yeem hloov cov ntaub ntawv nkag siab mus rau hauv cov teeb liab hluav taws xob lossis lwm cov ntaub ntawv xav tau ntawm cov ntaub ntawv tawm raws li qee txoj cai kom ua tau raws li cov kev xav tau ntawm cov ntaub ntawv xav tau rau kev sib kis, ua, cia, tso saib, kaw thiab tswj.
Cov yam ntxwv ntawm cov sensors muaj xws li: miniaturization, digitization, txawj ntse, multi-function, systematization, 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 kom muaj kev nkag siab xws li kov, saj, thiab tsw, thiab ua rau cov khoom maj mam ciaj sia. Nws feem ntau muab faib ua kaum pawg raws li nws cov kev paub yooj yim, suav nrog cov ntsiab lus thermal, cov ntsiab lus photosensitive, roj- cov ntsiab lus rhiab heev, quab yuam- cov ntsiab lus rhiab heev, sib nqus - cov ntsiab lus rhiab heev, av noo{ {4}}sensitive elements, sound-sensitive element, radiation-sensitive element, xim-sensitive element, and taste-sensitive elements. .
