(Nco Ntsoov Los Ntawm Tus Kws Kho: Tsab xov xwm no, txhais los ntawm ulinkmedia.)
Cov cuab yeej ntsuas tau dhau los ua qhov chaw nyob txhua qhov chaw. Lawv tau muaj ntev ua ntej Is Taws Nem, thiab yeej ntev ua ntej Is Taws Nem ntawm Yam (IoT). Cov cuab yeej ntsuas ntse niaj hnub no muaj rau ntau daim ntawv thov dua li yav dhau los, kev ua lag luam tab tom hloov pauv, thiab muaj ntau yam tsav tsheb rau kev loj hlob.
Cov tsheb, cov koob yees duab, cov xov tooj ntse, thiab cov tshuab hauv Hoobkas uas txhawb nqa Is Taws Nem ntawm Yam tsuas yog qee qhov ntawm ntau daim ntawv thov kev lag luam rau cov sensors.

Cov Sensors hauv Lub Ntiaj Teb Lub Cev ntawm Is Taws Nem
Nrog rau kev tshwm sim ntawm Internet of Things, kev hloov pauv ntawm kev tsim khoom (peb hu ua Kev Lag Luam 4.0), thiab peb txoj kev siv zog tas mus li rau kev hloov pauv digital hauv txhua qhov chaw ntawm kev lag luam thiab zej zog, cov cuab yeej ntse tau siv rau hauv ntau yam lag luam thiab kev ua lag luam sensor tau loj hlob sai dua thiab sai dua.
Qhov tseeb, qee txoj kev, cov cuab yeej ntse yog lub hauv paus "tiag tiag" ntawm Is Taws Nem ntawm Yam. Nyob rau theem no ntawm kev xa tawm iot, ntau tus neeg tseem txhais iot hauv cov nqe lus ntawm cov khoom siv iot. Is Taws Nem ntawm Yam feem ntau pom tias yog lub network ntawm cov khoom siv sib txuas, suav nrog cov cuab yeej ntse. Cov khoom siv no kuj tseem tuaj yeem hu ua cov khoom siv sensing.
Yog li ntawd, lawv suav nrog lwm yam thev naus laus zis xws li cov sensors thiab kev sib txuas lus uas tuaj yeem ntsuas tej yam thiab hloov qhov lawv ntsuas mus ua cov ntaub ntawv uas tom qab ntawd tuaj yeem siv rau ntau txoj hauv kev sib txawv. Lub hom phiaj thiab cov ntsiab lus ntawm daim ntawv thov (piv txwv li, siv cov thev naus laus zis sib txuas dab tsi) txiav txim siab seb cov sensors twg siv.
Cov Sensors thiab Cov Sensors Ntse - Dab tsi nyob rau hauv lub npe?

Cov Lus Txhais ntawm Sensors thiab Smart Sensors
Cov sensors thiab lwm yam khoom siv IoT yog lub hauv paus ntawm IoT thev naus laus zis. Lawv ntes cov ntaub ntawv uas peb cov ntawv thov xav tau thiab xa mus rau kev sib txuas lus siab dua, cov platform systems. Raws li peb piav qhia hauv peb cov lus qhia txog iot technology, iot "project" tuaj yeem siv ntau lub sensors. Hom thiab tus lej ntawm cov sensors siv nyob ntawm qhov xav tau ntawm project thiab kev txawj ntse ntawm project. Siv lub rig roj ntse: nws tuaj yeem muaj kaum tawm txhiab tus sensors.

Kev Txhais Lus ntawm Sensors
Cov sensors yog cov converters, zoo li cov actuators. Cov sensors hloov lub zog ntawm ib daim ntawv mus rau lwm daim. Rau cov sensors ntse, qhov no txhais tau tias cov sensors tuaj yeem "nkag siab" cov xwm txheej hauv thiab ib puag ncig cov khoom siv uas lawv txuas nrog thiab cov khoom siv uas lawv siv (xeev thiab ib puag ncig).
Cov sensors tuaj yeem ntes thiab ntsuas cov kev ntsuas no, cov xwm txheej, lossis kev hloov pauv thiab sib txuas lus rau cov kab ke siab dua thiab lwm yam khoom siv uas tuaj yeem siv cov ntaub ntawv rau kev tswj hwm, kev tshuaj xyuas, thiab lwm yam.
Ib lub sensor yog ib lub cuab yeej uas ntes, ntsuas, lossis qhia txog ib qho ntau ntawm lub cev (xws li lub teeb, cua sov, kev txav mus los, dej noo, siab, lossis lwm yam zoo sib xws) los ntawm kev hloov lawv mus rau lwm daim ntawv (feem ntau yog cov hluav taws xob) (los ntawm: United Market Research Institute).
Cov kev ntsuas thiab cov xwm txheej uas cov sensors tuaj yeem "hnov" thiab sib txuas lus suav nrog cov khoom siv lub cev xws li lub teeb, suab, siab, kub, kev co, av noo, muaj cov tshuaj lom neeg lossis roj, kev txav mus los, muaj cov hmoov av me me, thiab lwm yam.
Nws yog qhov tseeb tias cov sensors yog ib feem tseem ceeb ntawm Is Taws Nem ntawm Yam thiab yuav tsum tau ua kom raug heev vim tias cov sensors yog thawj qhov chaw kom tau txais cov ntaub ntawv.
Thaum lub sensor hnov thiab xa cov ntaub ntawv, lub actuator yuav qhib thiab ua haujlwm. Lub actuator tau txais lub teeb liab thiab teeb tsa qhov kev txav uas nws xav tau los ua haujlwm hauv ib puag ncig. Daim duab hauv qab no ua rau nws pom tseeb dua thiab qhia qee yam uas peb tuaj yeem "hnov". IoT sensors txawv ntawm qhov lawv siv cov modules sensor lossis cov laug cam tsim kho (feem ntau yog tsim los rau cov xwm txheej siv thiab daim ntawv thov tshwj xeeb) thiab lwm yam.

Kev Txhais Lus ntawm Smart Sensor
Lo lus "ntse" tau siv nrog ntau lwm cov lus ua ntej nws siv nrog Internet of Things. Cov tsev ntse, kev tswj cov khib nyiab ntse, tsev ntse, lub teeb ntse, cov nroog ntse, teeb pom kev zoo ntse, chaw ua haujlwm ntse, cov Hoobkas ntse thiab lwm yam. Thiab, tau kawg, cov sensors ntse.
Cov sensors ntse txawv ntawm cov sensors vim tias cov sensors ntse yog cov platforms siab heev nrog cov thev naus laus zis onboard xws li microprocessors, cia, kuaj mob thiab cov cuab yeej sib txuas uas hloov cov teeb liab tawm tswv yim ib txwm muaj rau hauv kev nkag siab digital tiag tiag (Deloitte)
Xyoo 2009, Lub Koom Haum International Frequency Sensors Association (IFSA) tau tshawb fawb ntau tus neeg los ntawm cov tsev kawm ntawv thiab kev lag luam los txhais lub sensor ntse. Tom qab hloov mus rau cov teeb liab digital hauv xyoo 1980 thiab ntxiv ntau yam thev naus laus zis tshiab hauv xyoo 1990, feem ntau cov sensors tuaj yeem hu ua cov sensors ntse.
Xyoo 1990 kuj tau pom qhov tshwm sim ntawm lub tswv yim ntawm "pervasive computing", uas yog suav hais tias yog ib qho tseem ceeb hauv kev txhim kho ntawm Internet of Things, tshwj xeeb tshaj yog thaum embedded computing nce qib. Nyob ib ncig ntawm nruab nrab xyoo 1990, kev txhim kho thiab kev siv cov khoom siv hluav taws xob digital thiab wireless hauv sensor modules txuas ntxiv mus loj hlob, thiab kev xa cov ntaub ntawv raws li kev xav thiab lwm yam tau dhau los ua qhov tseem ceeb. Niaj hnub no, qhov no pom tseeb hauv Internet of Things. Qhov tseeb, qee tus neeg tau hais txog sensor networks ua ntej lub sijhawm Internet of Things txawm tias muaj. Yog li, raws li koj tuaj yeem pom, ntau yam tau tshwm sim hauv qhov chaw sensor ntse hauv xyoo 2009.
