Lub dav tshaj lub ntsiab lus ntawm sensor

Hauv kev txhais dav dav, tus sensor yog ib qho hluav taws xob, module, lossis subsystem uas nws lub hom phiaj yog txhawm rau paub txog cov txheej xwm lossis kev hloov hauv nws cheeb tsam thiab xa cov ntaub ntawv mus rau lwm yam khoom siv hluav taws xob, feem ntau yog ib lub computer processor. Ib qho sensor yeej ib txwm siv nrog lwm yam khoom siv hluav taws xob, seb yooj yim npaum li lub teeb los yog ua txoj hauv lub computer.

Sensors siv nyob rau hauv txhua txhua hnub khoom xws li kov-sensitive elevator cov nyees khawm (tactile sensor) thiab cov teeb uas dim los yog brighten los ntawm kov lub hauv paus, dua li cov ntawv suav tsis txheeb uas feem ntau cov neeg tsis paub. Nrog cov kev kho tshiab hauv micromachinery thiab cov chaw siv microcontroller yooj yim, cov kev siv ntawm cov sensors tau nthuav dav tshaj qhov chaw ntawm kev ntsuas kub, kev ntsuas siab los sis kev ntsuas, [1] Piv txwv rau hauv MARG sensors. Ntxiv mus, analog sensors xws li potentiometers thiab quab yuam-sensing resistors tseem siv dav. Cov ntawv thov muaj xws li kev tsim khoom thiab cov tshuab, cov dav hlau thiab cov tsav tsheb, cov tsheb, cov tshuaj, cov neeg hlau, thiab ntau yam ntawm peb lub neej.

Ib lub sensor tus rhiab heev qhia tias ntau npaum li cas tus sensor cov zis hloov thaum lub sij hawm ntau uas raug ntsuas cov kev hloov. Piv txwv li, yog tias cov mercury nyob rau hauv tus pas ntsuas kub tsiv 1cm thaum ntsuas kub hloov ntawm 1 ° C, qhov tseem ceeb yog 1cm / ° C (nws yog qhov nqes hav Dy / Dx piv txwv tias yog tus cwj pwm). Qee tus sensors kuj tuaj yeem ua rau lawv ntsuas; Piv txwv, chav kub kub thermometer ntsaws rau hauv kub kub ntawm kua txias lub kua thaum cov kua ua kom sov tus pas ntsuas kub. Sensors feem ntau yog tsim los kom muaj cov nyhuv me me ntawm qhov ntsuas; Ua tus sensor me me feem ntau zoo dua qhov no thiab kuj yuav qhia lwm yam zoo. Txoj kev ua haujlwm ntawm cov kev tso cai pub rau ntau thiab ntau yam khoom siv los ua kom pom ntawm lub tshuab me me li microsensors siv MEMS technology. Feem ntau, tus microsensor nce mus txog kev ceev ceev thiab rhiab heev piv nrog cov kev xav tau.
