Hauv peb lub neej niaj hnub, cov duab sensors twb nyob txhua qhov chaw -lawv yog qhov tseem ceeb hauv cov xwm txheej xws li kev yees duab xov tooj ntawm tes, kev soj ntsuam video kaw, thiab paub lub ntsej muag. Raws li "tus tswv cuab tshwj xeeb" ntawm lawv, NIR duab sensor ua lub luag haujlwm hloov tsis tau hauv ntau qhov chaw los ntawm kev tsim txiaj ntawm nws lub peev xwm los pom ze rau - lub teeb infrared. Yog li, dab tsi yog qhov NIR duab sensor? Thiab nws muaj cov yam ntxwv tshwj xeeb dab tsi?
Ua ntej tshaj plaws, cia peb qhia meej txog lub ntsiab lus tseem ceeb: NIR yog lub ntsiab lus ntawm "Near-Infrared", uas yog hais txog ze - lub teeb infrared. Nws qhov wavelength ntau yog feem ntau ntawm 780 nanometers (nm) thiab 2500 nanometers, uas yog nyob rau hauv cheeb tsam spectral pom tsis tau rau tib neeg lub qhov muag. NIR duab sensor yog ib qho khoom siv hluav taws xob uas tuaj yeem ntes tau nyob ze -infrared teeb liab, hloov lawv mus rau hauv cov teeb liab hluav taws xob, thiab thaum kawg tsim cov duab. Sib txawv ntawm cov duab pom lub teeb pom kev zoo peb feem ntau siv, nws "tsis pom kev" tuaj yeem nkag mus rau qhov pom kev txwv ntawm tib neeg lub qhov muag thiab ntes cov ntaub ntawv zais dhau qhov pom lub teeb.
Cov yam ntxwv tseem ceeb ntawm NIR Duab Sensors
1. Nyob ze -Infrared Light Sensing Capability, Ua txhaum ntawm tib neeg kev pom kev txwv
Qhov no yog tus yam ntxwv tseem ceeb ntawm NIR duab sensors. Tib neeg lub qhov muag tsuas yog pom lub teeb pom kev nrog wavelengths ntawm 380nm thiab 780nm, thaum nyob ze - lub teeb infrared yog qhov pom tsis pom uas tsis tuaj yeem ntes ncaj qha los ntawm tib neeg lub qhov muag. Los ntawm kev tsim tshwj xeeb ntawm cov duab tsis pom kev, NIR cov duab sensors tuaj yeem ua raws lub teeb nyob ze ntawm -infrared band thiab hloov tsis pom nyob ze -infrared teeb rau hauv cov duab pom. Piv txwv li, nyob rau hauv ib qho chaw tsaus ntuj nti, tsuav yog muaj qhov ze ntawm -infrared lub teeb (xws li lub teeb infrared sau), NIR duab sensor tuaj yeem ntes cov qauv thiab cov ntsiab lus ntawm cov khoom. Cov yam ntxwv no ua rau nws yog ib feem tseem ceeb ntawm kev saib xyuas hmo ntuj thiab cov khoom siv pom kev hmo ntuj.
2. Muaj zog Environmental Adaptability thiab Outstanding Anti-Interference Ability
Kev ua tau zoo ntawm NIR duab sensors nyob rau hauv ib puag ncig nyuaj yog qhov zoo tshaj plaws ntawm cov teeb pom kev zoo ib txwm muaj. Ntawm qhov tod tes, nws raug cuam tshuam tsawg kawg nkaus los ntawm cov teeb pom kev zoo thiab tuaj yeem ua haujlwm ruaj khov hauv cov xwm txheej xws li lub teeb muaj zog ncaj qha, qis - qhov chaw teeb pom kev zoo, lossis kev tsaus ntuj. Nyob rau hauv lub hnub ci muaj zog, pom lub teeb pom kev tuaj yeem ua rau pom ntau dhau thiab poob ntawm cov ntsiab lus vim lub teeb ci ntau dhau, thaum NIR cov duab sensors tuaj yeem lim tawm lub teeb pom kev, tsom rau ze rau - cov teeb liab infrared, thiab tsis txhob cuam tshuam lub teeb muaj zog; nyob rau hauv huab cua hnyav xws li huab cua, nag, thiab daus, nyob ze - lub teeb infrared muaj zog nkag tau zoo dua li pom lub teeb, thiab NIR cov duab sensors tseem tuaj yeem ntes cov duab meej, ua kom muaj kev ua haujlwm ib txwm muaj xws li kev saib xyuas thiab kev tsav tsheb. Ntawm qhov tod tes, nws tsis nkag siab rau cov kev hloov ntawm cov xim thiab cov duab ntxoov ntxoo hauv ib puag ncig, tuaj yeem txheeb xyuas cov yam ntxwv tseem ceeb ntawm cov khoom, thiab txo qhov kev lees paub yuam kev los ntawm ib puag ncig cuam tshuam.
3. Muaj Peev Xwm Penetrability, Muaj peev xwm ntes cov ntaub ntawv zais
Nyob ze - lub teeb infrared tuaj yeem nkag mus rau qee yam khoom uas pom lub teeb tsis tuaj yeem, qhov tshwj xeeb uas tso cai rau NIR cov duab sensors nrog "saib- dhau ntawm" muaj peev xwm. Piv txwv li, nws tuaj yeem nkag mus rau cov pa taws thiab plua plav, ua kom pom tseeb hauv qhov xwm txheej hauv qhov hluav taws kub lossis qhov chaw muaj plua plav, muab cov ntaub ntawv tseem ceeb rau kev cawm thiab kev saib xyuas ntau lawm; nyob rau hauv kev ua liaj ua teb, nyob ze - lub teeb infrared tuaj yeem nkag mus rau txheej txheej ntawm cov nroj tsuag nplooj, qhia txog cov ntsiab lus chlorophyll thiab noo noo nyob rau hauv nplooj, pab cov neeg ua liaj ua teb kom txiav txim siab txog kev loj hlob ntawm cov qoob loo; nyob rau hauv qhov chaw soj ntsuam zaub mov, nws tuaj yeem nkag mus rau cov ntim khoom noj kom pom qhov zoo thiab muaj cov impurities, ua kom cov zaub mov muaj kev nyab xeeb.
4. Kev siv hluav taws xob tsawg thiab kev ruaj ntseg siab, haum rau ntau yam kev thov
Lub hauv paus ntsiab lus ua haujlwm ntawm NIR cov duab sensors txiav txim siab lawv lub zog siv hluav taws xob tsawg. Piv nrog rau qee cov khoom siv yees duab uas xav tau kev pab lub teeb pom kev zoo, NIR cov duab sensors tuaj yeem ua haujlwm ib txwm nrog qis -lub zog nyob ze -infrared sau lub teeb, ua rau lawv tshwj xeeb tshaj yog tsim rau cov khoom siv uas yuav tsum tau ua haujlwm tsis tu ncua ntev, xws li cov koob yees duab saib xyuas kev ruaj ntseg thiab IoT sensing cov cuab yeej, uas tuaj yeem txo cov khoom siv hluav taws xob thiab siv cov nqi. Nyob rau tib lub sijhawm, lawv cov khoom siv photosensitive feem ntau yog ua los ntawm siab - cov ntaub ntawv ruaj khov semiconductor, uas tuaj yeem hloov mus rau ntau qhov chaw ua haujlwm hnyav xws li kub thiab qis, av noo, thiab kev co, thiab muaj lub neej ua haujlwm ntev. Lawv ua tau zoo heev nyob rau hauv cov xwm txheej uas yuav tsum muaj siab rau cov cuab yeej ruaj ntseg xws li kev tswj hwm kev lag luam thiab kev saib xyuas sab nraum zoov.
5. Kev sib tw muaj zog, kev sib koom ua ke yooj yim thiab nthuav dav
NIR duab sensors muaj kev sib raug zoo nrog cov tsoos pom lub teeb duab sensors nyob rau hauv cov nqe lus ntawm kho vajtse qauv thiab interface tsim, ua rau lawv yooj yim rau kev koom ua ke rau hauv cov duab uas twb muaj lawm. Txawm hais tias nws yog cov neeg siv khoom siv hluav taws xob xws li xov tooj ntawm tes thiab lub koob yees duab, lossis cov cuab yeej tshaj lij xws li cov cuab yeej ntsuas kev lag luam thiab cov khoom siv kho mob, NIR cov duab pom kev ua haujlwm tuaj yeem ntxiv los ntawm kev hloov kho yooj yim thiab hloov kho. Tsis tas li ntawd, nrog kev txhim kho thev naus laus zis, NIR cov duab sensors kuj tuaj yeem ua ke nrog cov thev naus laus zis xws li kev txawj ntse thiab cov ntaub ntawv loj kom paub txog ntau txoj haujlwm nyuaj, xws li ze rau -infrared lub ntsej muag paub, kev faib khoom raug, thiab kev saib xyuas kev noj qab haus huv, nthuav dav daim ntawv thov ciam teb.
Hauv kev xaus, tso siab rau nws lub peev xwm tshwj xeeb kom pom tau ze ntawm - lub teeb infrared, nrog rau cov txiaj ntsig zoo xws li muaj zog ib puag ncig adaptability, penetrability, thiab siv hluav taws xob tsawg, NIR cov duab sensors ua lub luag haujlwm tseem ceeb hauv ntau yam xws li kev saib xyuas kev ruaj ntseg, kev sim ua liaj ua teb, zaub mov kev nyab xeeb, kev noj qab haus huv, thiab kev tsav tsheb tsis muaj zog. Nrog kev nce qib ntawm kev siv thev naus laus zis, kev ua tau zoo ntawm NIR cov duab sensors yuav txuas ntxiv txhim kho, thiab lawv daim ntawv thov scenarios yuav dhau los ua ntau dua, nqa kev yooj yim dua thiab kev tsim kho tshiab rau peb lub neej thiab kev tsim khoom.
