Photosensitive sensor

Photosensitive sensor yog ib qho khoom siv hluav taws xob zoo tshaj plaws uas tuaj yeem tswj tau qhov kev hloov pauv tsis siv neeg ntawm lub voj voog vim qhov kev hloov ntawm lub teeb pom kev thaum kaj ntug thiab tsaus ntuj (hnub sawv thiab hnub poob).Lub photosensitive sensor tuaj yeem tswj qhov qhib thiab kawLED teeb pom kev zooraws li huab cua, lub sij hawm lub sij hawm thiab cheeb tsam.Nyob rau hauv cov hnub ci, lub zog noj yog txo los ntawm kev txo nws cov zis zog.Piv nrog rau kev siv cov roj teeb fluorescent, lub khw muag khoom yooj yim nrog thaj tsam ntawm 200 square metres tuaj yeem txo qhov kev siv hluav taws xob los ntawm 53% feem ntau, thiab kev pabcuam lub neej yog li 50000 ~ 100000 teev.Feem ntau, kev pab cuam lub neej ntawm LED teeb pom kev zoo yog txog 40000 teev;Cov xim ntawm lub teeb kuj tuaj yeem hloov pauv hauv RGB kom lub teeb muaj xim ntau dua thiab cov cua muaj zog dua.

Infrared sensor

Lub infrared sensor ua haujlwm los ntawm kev kuaj cov infrared tawm los ntawm tib neeg lub cev.Lub hauv paus ntsiab lus tseem ceeb yog: 10 npaug ntawm tib neeg lub cev emission μ Cov kab hluav taws xob infrared ntawm M yog txhim kho los ntawm Fresnel lim lens thiab sib sau ua ke ntawm pyroelectric element PIR detector.Thaum tib neeg txav mus, txoj hauj lwm emission ntawm infrared hluav taws xob yuav hloov, lub caij yuav poob tus nqi tshuav, tsim cov nyhuv pyroelectric thiab tso cov nqi tawm sab nraud.Lub infrared sensor yuav hloov pauv lub zog hluav taws xob infrared los ntawm Fresnel lim lens rau hauv hluav taws xob teeb liab, Thermoelectric conversion.Thaum tsis muaj tib neeg lub cev txav mus rau hauv qhov chaw kuaj pom ntawm lub ntsuas hluav taws xob infrared, lub ntsuas hluav taws xob infrared tsuas hnov ​​​​qab qhov kub thiab txias.Thaum tib neeg lub cev nkag mus rau qhov chaw kuaj pom, los ntawm Fresnel lens, pyroelectric infrared sensor paub qhov sib txawv ntawm tib neeg lub cev kub thiab qhov kub thiab txias tom qab, tom qab lub teeb liab tau sau, nws muab piv nrog cov ntaub ntawv tshawb pom uas twb muaj lawm hauv lub kaw lus los txiav txim. seb ib tug neeg thiab lwm qhov chaw infrared nkag mus rau qhov chaw kuaj pom.

LED Motion Sensor Teeb

Ultrasonic sensor

Ultrasonic sensors, zoo ib yam li infrared sensors, tau siv ntau thiab ntau dua nyob rau hauv tsis siv neeg nrhiav kom tau cov khoom txav hauv xyoo tas los no.Lub ultrasonic sensor tsuas yog siv Doppler txoj cai kom emit high-frequency ultrasonic tsis uas tshaj tib neeg lub cev txoj kev xaav los ntawm cov siv lead ua oscillator.Feem ntau, 25 ~ 40KHz nthwv dej raug xaiv, thiab tom qab ntawd tus tswj module pom qhov zaus ntawm qhov cuam tshuam yoj.Yog tias muaj kev txav ntawm cov khoom hauv cheeb tsam, qhov cuam tshuam yoj zaus yuav hloov pauv me ntsis, uas yog, Doppler nyhuv, thiaj li txiav txim siab qhov txav ntawm cov khoom hauv thaj chaw teeb pom kev zoo, thiaj li tswj tau qhov hloov.

Kub sensor

Kub sensor NTC yog dav siv raws li kub tiv thaiv ntawmLEDteeb.Yog tias muaj lub zog loj LED teeb pom kev zoo tau txais rau LED teeb, ntau lub tis aluminium radiator yuav tsum tau txais yuav.Vim yog qhov chaw me me ntawm LED teeb rau sab hauv tsev teeb pom kev zoo, qhov teeb meem ntawm cov cua sov dissipation tseem yog ib qho ntawm cov teeb meem loj tshaj plaws nyob rau tam sim no.

Tsis zoo cua sov dissipation ntawm LED teeb yuav ua rau ntxov teeb tsis ua hauj lwm ntawm LED teeb qhov chaw vim overheating.Tom qab lub teeb ci LED tau qhib, cov cua sov yuav ua kom muaj zog rau lub teeb lub hau vim qhov kub tsis siv neeg nce siab, uas yuav cuam tshuam rau lub neej kev pab cuam ntawm lub hwj huam mov.Yog li ntawd, thaum tsim cov teeb ci LED, lub NTC tuaj yeem nyob ze rau ntawm lub tshuab hluav taws xob txhuas nyob ze ntawm lub teeb ci LED kom khaws qhov kub ntawm lub teeb hauv lub sijhawm.Thaum qhov kub ntawm aluminium radiator ntawm lub khob khob nce siab, qhov Circuit Court no tuaj yeem siv los txo cov zis tam sim no ntawm qhov chaw tam sim no kom txias lub teeb;Thaum qhov kub ntawm aluminium radiator ntawm lub khob khob nce mus rau qhov txwv qhov nqi, LED fais fab mov yuav raug kaw kom paub txog qhov kub tiv thaiv ntawm lub teeb.Thaum qhov kub thiab txias poob, lub teeb yuav cia li qhib dua.

Lub suab sensor

Lub suab tswj sensor yog tsim los ntawm lub suab tswj sensor, suab amplifier, channel xaiv Circuit Court, ncua qhib Circuit Court thiab thyristor tswj Circuit Court.Txiav txim seb puas yuav pib lub tswj Circuit Court raws li lub suab sib piv cov txiaj ntsig, thiab teeb tsa tus nqi qub ntawm lub suab tswj sensor nrog lub regulator.Lub suab tswj sensor tas li sib piv cov suab sab nraud nrog tus nqi qub, thiab xa cov teeb liab "suab" mus rau qhov chaw tswj xyuas thaum nws tshaj qhov qub.Lub suab tswj sensor yog dav siv nyob rau hauv txoj kev hauv tsev thiab cov chaw teeb pom kev zoo.

Microwave induction sensor

Microwave induction sensor yog cov khoom txav txav khoom tsim los ntawm lub hauv paus ntsiab lus ntawm Doppler nyhuv.Nws tshawb pom seb txoj hauj lwm ntawm cov khoom txav mus rau hauv txoj kev tsis sib cuag, thiab tom qab ntawd tsim cov kev hloov pauv sib raug.Thaum ib tug neeg nkag mus rau qhov chaw paub thiab ncav cuag qhov xav tau ntawm lub teeb pom kev zoo, qhov hloov pauv hloov pauv yuav cia li qhib, cov khoom siv thauj khoom yuav pib ua haujlwm, thiab lub kaw lus qeeb yuav pib.Tsuav tib neeg lub cev tsis tawm ntawm qhov chaw paub, lub tshuab nqa khoom yuav ua haujlwm ntxiv.Thaum tib neeg lub cev tawm ntawm qhov chaw nkag mus, lub sensor pib xam qhov qeeb.Thaum kawg ntawm kev ncua, lub sensor hloov tau kaw thiab cov khoom siv thauj khoom tsis ua haujlwm.Muaj kev nyab xeeb tiag tiag, yooj yim, ntse thiab txuag hluav taws xob.
