Uluvo lwefoto

I-sensor ye-Photosensitive yinzwa ye-elektroniki efanelekileyo enokulawula ukutshintshwa ngokuzenzekelayo kwesekethe ngenxa yokutshintsha kokukhanya ngokusa kunye nobumnyama (ukuphuma kwelanga kunye nokutshona kwelanga). Inzwa yefoto inokulawula ngokuzenzekelayo ukuvulwa nokuvalwa kweIzibane zokukhanyisa ze-LEDngokwemozulu, ixesha kunye nommandla. Ngeentsuku eziqaqambileyo, ukusetyenziswa kwamandla kuyancitshiswa ngokunciphisa amandla ayo okuvelisa. Xa kuthelekiswa nokusetyenziswa kwezibane ze-fluorescent, isitolo esilula esinendawo ye-square metres ye-200 inokunciphisa ukusetyenziswa kwamandla ngama-53% kakhulu, kwaye ubomi benkonzo malunga ne-50000 ~ 100000 iiyure. Ngokuqhelekileyo, ubomi benkonzo yezibane zokukhanyisa i-LED malunga neeyure ze-40000; Umbala wokukhanya ungatshintshwa kwi-RGB ukwenza ukukhanya kube nemibala ngakumbi kwaye umoya usebenze ngakumbi.

Isivamvo se-infrared

Inzwa ye-infrared isebenza ngokubona i-infrared ekhutshwa ngumzimba womntu. Umgaqo ophambili ngulo: Amaxesha ali-10 okuphuma komzimba womntu μ Ireyitha ye-infrared emalunga ne-M iphuculwe ngelensi yokucoca iFresnel kwaye iqokelelwe kwisixhobo sombane se-PIR. Xa abantu behamba, indawo yokukhutshwa kwemitha ye-infrared iya kutshintsha, into iya kuphulukana nebhalansi yentlawulo, ivelise umphumo we-pyroelectric kwaye ikhulule intlawulo ngaphandle. Inzwa ye-infrared iya kuguqula utshintsho lwamandla emitha ye-infrared ngokusebenzisa i-lens yokucoca i-Fresnel ibe ngumqondiso wombane, ukuguqulwa kwe-Thermoelectric. Xa kungekho mzimba womntu oshukumayo kwindawo yokubhaqwa ye-infrared detector, i-infrared sensor iva kuphela ubushushu obungasemva. Xa umzimba womntu ungena kwindawo yokufumanisa, nge-Fresnel lens, i-pyroelectric infrared sensor ibona umahluko phakathi kobushushu bomzimba womntu kunye nobushushu obungasemva, Emva kokuba uphawu luqokelelwe, lufaniswa nedatha ekhoyo yokufumanisa kwinkqubo yokugweba. nokuba umntu kunye neminye imithombo ye-infrared ingena kwindawo yobhaqo.

UkuKhanya kweSensori yeMotion ye-LED

Inzwa ye-ultrasonic

Izinzwa ze-Ultrasonic, ezifana ne-infrared sensors, ziye zasetyenziswa ngakumbi nangakumbi ekuboneni ngokuzenzekelayo izinto ezihambayo kwiminyaka yamuva. I-sensor ye-ultrasonic ikakhulu isebenzisa umgaqo we-Doppler ukukhupha amaza e-ultrasonic ajikelezayo adlula ukuqonda komzimba womntu nge-crystal oscillator. Ngokubanzi, i-25 ~ 40KHz wave ikhethiwe, kwaye imodyuli yokulawula ibona ukuphindaphinda kwamaza abonakalisiweyo. Ukuba kukho ukuhamba kwezinto kwindawo, i-frequency wave ebonakalisiweyo iya kuguquguquka kancinane, oko kukuthi, i-Doppler effect, ukuze ugwebe ukuhamba kwezinto kwindawo yokukhanyisa, ukuze ulawule ukutshintsha.

Isivamvo sobushushu

Ubushushu boluvo lwe-NTC lusetyenziswa ngokubanzi njengokhuselo lobushushu obungaphezulu kweI-LEDizibane. Ukuba umthombo wokukhanya we-LED wamandla aphezulu wamkelwe kwizibane ze-LED, iradiyetha ye-aluminium yamaphiko amaninzi kufuneka yamkelwe. Ngenxa yesithuba esincinci sezibane ze-LED zokukhanyisa ngaphakathi, ingxaki yokutshatyalaliswa kobushushu iseyeyona nto ibalulekileyo yobugcisa okwangoku.

Ukutshatyalaliswa kokushisa okungalunganga kwezibane ze-LED kuya kukhokelela ekungaphumeleli kokukhanya kwangaphambili komthombo wokukhanya kwe-LED ngenxa yokushisa okukhulu. Emva kokuba isibane se-LED sivuliwe, ukushisa kuya kutyetyiswa kwisibane sesibane ngenxa yokunyuka ngokuzenzekelayo komoya oshushu, okuya kuchaphazela ubomi benkonzo yokunikezelwa kwamandla. Ngoko ke, xa uyila izibane ze-LED, i-NTC ingaba kufuphi ne-radiator ye-aluminium kufuphi nomthombo wokukhanya kwe-LED ukuqokelela ubushushu bezibane ngexesha langempela. Xa ubushushu be-radiator ye-aluminium yesibane sekomityi buphakama, le sekethi ingasetyenziselwa ukunciphisa ngokuzenzekelayo imveliso yangoku yomthombo oqhubekayo wangoku ukupholisa izibane; Xa iqondo lobushushu leradiyetha ye-aluminium yekomityi yesibane linyuka ukuya kwixabiso lokumisela umda, umbane we-LED ucinywa ngokuzenzekelayo ukuze uqaphele ukukhuselwa kobushushu besibane. Xa ubushushu buyancipha, isibane sivulwa ngokuzenzekelayo kwakhona.

Isivamvo selizwi

I-sensor yokulawula isandi iqulethwe inzwa yokulawula isandi, i-audio amplifier, isiphaluka sokukhethwa kwesiteshi, isiphaluka sokulibaziseka kunye nesiphaluka sokulawula i-thyristor. Gweba ukuba uqalise isiphaluka solawulo ngokusekelwe kwiziphumo zokuthelekisa isandi, kwaye usethe ixabiso lokuqala lenzwa yokulawula isandi kunye nomlawuli. I-sensor yokulawula isandi isoloko ithelekisa ukuqina kwesandi sangaphandle kunye nexabiso lokuqala, kwaye idlulisela uphawu "lwesandi" kwiziko lolawulo xa lidlula ixabiso lokuqala. Inzwa yokulawula isandi isetyenziswa ngokubanzi kwiicorridors kunye neendawo zokukhanyisa uluntu.

Inzwa yokungeniswa kweMicrowave

Inzwa ye-Microwave induction detector yinto ehambayo eyenzelwe ngokusekelwe kumgaqo weDoppler effect. Ibona ukuba indawo yento ihamba ngendlela engeyiyo yoqhagamshelwano, kwaye emva koko ivelise ukusebenza kokutshintsha okuhambelanayo. Xa umntu engena kwindawo yokuva kwaye efikelela kwimfuno yokukhanyisa, ukutshintshela inzwa kuya kuvuleka ngokuzenzekelayo, isixhobo somthwalo siya kuqala ukusebenza, kwaye inkqubo yokulibaziseka iya kuqaliswa. Ngethuba nje umzimba womntu ungashiyi indawo yokuva, isixhobo somthwalo siya kuqhubeka sisebenza. Xa umzimba womntu ushiya indawo yokuva, inzwa iqala ukubala ukulibaziseka. Ekupheleni kokulibaziseka, i-sensor switch ivala ngokuzenzekelayo kwaye isixhobo somthwalo siyayeka ukusebenza. Ikhuselekile ngokwenene, iluncedo, ikrelekrele kwaye igcina amandla.
