Yog tias koj tsis xav hloov lub teeb pom kev zoo rau thiab tawm, ces kev yuav khoom sensors rau koj lub teeb pom kev zoo LED yog qhov kev daws teeb meem zoo tshaj. Koj puas tseem tsis tau paub meej tias lub teeb pom kev zoo ntawm LED teeb pom kev zoo li cas koj tab tom nrhiav? Nyob rau hauv tsab xov xwm no, peb piav qhia raws nraim li cas LED teeb pom kev zoo sensors siv rau thiab dab tsi txawv sensors muaj.
Dab tsi yog LED sensors siv rau?
Txawm hais tias koj xav kom txaus siab rau qhov kev nyab xeeb ntawm lub teeb pom kev zoo ntawm lub qhov rooj tom qab thaum koj tuaj txog hauv tsev thaum yav tsaus ntuj lossis xav mus rau chav dej yam tsis tas yuav hloov lub teeb pom kev zoo: LED teeb pom kev zoo sensors tuaj yeem muab kev daws teeb meem hauv ob qho xwm txheej. LED teeb pom kev zoo sensors yog siv rau kev hloov pauv LED teeb pom kev rau thiab tawm. Tsis tsuas yog siv cov sensors zoo li no kom ntseeg tau tias lub teeb pom kev tsis tas yuav tsum nyob ntev dua li qhov tsim nyog thiab koj tuaj yeem txuag hluav taws xob ncaj qha nrog nws. Nws kuj tseem ua kom paub tseeb tias koj tsis tas yuav ua xyem xyav seb koj puas tau kaw lub teeb lossis tsis tau.
Ntau hom LED teeb pom kev zoo sensors
Tau ntau xyoo, ntau thiab ntau ntau yam ntawm LED teeb pom kev zoo sensors tau nkag mus rau hauv kev ua lag luam. Thaum koj xav yuav sensors rau LED teeb pom kev zoo, koj feem ntau muaj kev xaiv ntawm twilight sensors, HF sensors, thiab PIR suab sensors.
Dusk sensors coj twilight sensor
Koj puas xav kom koj lub teeb sab nraum zoov qhib nws thaum nws tsaus muag sab nraum? Los ntawm kev siv lub twilight sensor koj tuaj yeem xyuas kom meej tias lub teeb pom kev zoo LED tau hloov pauv thiab tawm thaum nws tsaus. Lub twilight sensors uas yog ntsuas lub teeb siv thiab txiav txim siab raws li tus nqi preset seb lub teeb pom kev zoo yuav tsum tau hloov los yog tawm. Twilight sensors muaj qhov zoo dua uas lub teeb pom kev tsuas yog hloov thaum koj xav siv nws.
Qhov twg lub sij hawm hloov ua kom lub teeb pom kev zoo ib txwm hloov ntawm lub sijhawm tshwj xeeb, twilight sensors xyuas kom meej tias lub teeb pom kev tsuas yog hloov thaum tsaus ntuj txaus. Thaum lub caij ntuj no tsaus ntuj, lub twilight sensor xyuas kom meej tias lub teeb pom kev zoo ntawm LED tau hloov thaum tav su thiab thaum lub caij ntuj sov, lub twilight sensor ua kom lub teeb pom kev zoo thaum yav tsaus ntuj. Vim yog siv pob ntseg twilight, koj yeej tsis tau los tsev hauv qhov tsaus ntuj.
PIR suab sensor
Koj puas pom tias hauv txaj thaum yav tsaus ntuj koj feem ntau tsis ntseeg tias koj puas tau tua tag nrho cov teeb? Puas yog koj tab tom nrhiav rau LED teeb pom kev zoo sensor uas cia li hloov lub teeb pom kev zoo rau thiab tawm raws li kev kuaj pom? Tom qab ntawd muaj lub caij nyoog zoo uas PIR suab sensor ua tau raws li qhov koj xav tau.
PIR (Passive Infrared) cov lus tsa suab sensor txiav txim siab raws li kev txav mus los, piv txwv li, 6 meters los ntawm lub sensor seb nws puas tsim nyog hloov lub teeb pom kev zoo. Tom qab lub sensor tsis pom kev txav tom qab ib pliag. LED teeb pom kev zoo yuav raug hloov pauv tsis siv neeg LED PIR sensor. Thaum muas lub PIR suab sensor, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau qhov ntsuas qhov deb. Rau qhov chaw me me xws li chav dej lossis chav dej. Qhov kev tshawb pom luv luv txog li 3 meters yog txaus. Thaum piv txwv li chav ua noj nrhiav pom qhov deb txog li 6 meters feem ntau xav tau.
HF suab sensor
Puas yog koj tab tom npaj yuav nruab ib lub teeb pom kev zoo ntawm LED nyob rau hauv ib chav puv? Tom qab ntawd nws yuav muaj txiaj ntsig zoo los yuav lub RF motion sensor es tsis yog PIR motion sensor. Ib qho HF (High Frequency) sensor kuj pom kev txav los ntawm iav, rooj tog thiab txawm tias nyias qhov rooj thiab phab ntsa. Rau qhov chaw uas nws feem ntau muaj plua plav, xws li chaw nres tsheb. Cov lus tsa suab no feem ntau ua tau zoo dua li tus qauv PIR suab sensor.
HF sensor tseem yuav ua haujlwm
HF sensor tseem yuav ua haujlwm thaum muaj plua plav tawm ntawm lub lens. Tsis tas li ntawd, ib qho HF sensor feem ntau pom kev txav nrawm dua. Thiab ntau dua nrog kev hwm rau PIR motion sensor. Qhov no kuj yog ib qho laj thawj xaiv rau HF motion sensor.
