Dab tsi yog humidity sensor?
Humidity sensors tuaj yeem txhais tau tias yog cov khoom siv hluav taws xob qis qis uas siv los ntsuas cov av noo. Humidity sensors tseem hu ua hygrometers. Txoj kev ntsuas cov av muaj xws li cov av noo, tsis muaj av noo thiab txheeb ze humidity. Ob lub ntsiab ntawm cov av noo sensors tau muab faib ua cov av noo sensors thiab txheeb ze humidity sensors.
Raws li cov khoom siv los ntsuas cov av noo, cov sensors no tau muab faib ua thermal humidity sensors, resistive humidity sensors, thiab capacitive humidity sensors. Qee qhov kev ntsuas thaum xav txog cov sensors no yog lub sijhawm teb, qhov tseeb, kev ntseeg tau, thiab linearity.
Ua hauj lwm hauv paus ntsiab lus ntawm humidity sensor
Humidity sensor yog ib qho khoom siv tseem ceeb uas pab ntsuas cov av noo ntawm ib puag ncig ib puag ncig. Feem ntau, cov sensors no muaj cov khoom siv uas paub cov av noo thiab lub thermistor uas ntsuas qhov kub thiab txias. Piv txwv li, lub ntsiab lus ntawm lub capacitor sensor yog lub capacitor. Nyob rau hauv ib tug txheeb ze humidity sensor uas xam cov txheeb ze humidity tus nqi, qhov kev hloov nyob rau hauv permittivity ntawm cov khoom dielectric yog ntsuas.
Cov ntaub ntawv siv los tsim cov sensors tsis muaj zog. Cov ntaub ntawv tiv thaiv no tau muab tso rau saum ob lub electrodes. Thaum tus nqi resistivity ntawm cov khoom no hloov, qhov hloov ntawm cov av yog ntsuas. Cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov ntsev yog cov piv txwv ntawm cov khoom siv hluav taws xob siv los tsim cov sensors tiv thaiv. Qhov tseeb cov av noo qhov tseem ceeb, ntawm qhov tod tes, yog ntsuas los ntawm thermal conductivity sensors. Tam sim no cia saib yuav ua li cas cov av noo sensor ua haujlwm.
Kev siv cov humidity sensor
Capacitive txheeb ze humidity sensors yog siv los ntsuas cov av noo hauv cov tshuab luam ntawv, HVAC tshuab, fax tshuab, tsheb, chaw nres tsheb huab cua, tub yees, ua zaub mov, thiab lwm yam. Vim lawv qhov me me thiab tus nqi qis, cov khoom siv hluav taws xob tiv thaiv tau siv hauv tsev, thaj chaw thiab kev lag luam. Thermal conductivity sensors feem ntau yog siv rau hauv tshuab ziab khaub ncaws, khoom noj khoom haus lub cev qhuav dej, tshuaj nroj tsuag, thiab lwm yam.
Peb cov av noo thiab kub sensor yog ua raws li kev npaj lub peev xwm thev naus laus zis uas sib xyaw cov av noo thiab ntsuas kub hauv qhov ntsuas qhov ntsuas. Siv peb cov kev paub dhau los hauv kev nyeem cov kev hloov pauv me me hauv accelerometers thiab gyroscopes, peb tau tsim qhov sib txawv capacitance sensing lub caij uas, thaum ua ke nrog qhov ntsuas kub, muab cov txheeb ze av noo. Nws yog ib qho yooj yim rau siv nrog lub sensor, teeb liab ua circuitry, onboard calibration thiab proprietary algorithm intergrated nyob rau hauv ib lub pob.
Qhov loj me thiab siv hluav taws xob tsawg yog qhov zoo tagnrho rau kev siv cov neeg siv khoom siv txawb, lub tsev ntse (cov khoom siv hauv tsev thiab HVAC), thiab kev khaws cia thiab kev siv logistic.
