Lub photocell, tseem hu ua photoresistor los yog lub teeb-dependent resistor (LDR), yog ib hom resistor uas hloov nws qhov kev tiv thaiv raws li tus nqi ntawm lub teeb uas poob rau ntawm nws.Qhov tsis kam ntawm photocell txo qis thaum qhov kev siv ntawm lub teeb nce thiab rov ua dua.Qhov no ua rau photocells muaj txiaj ntsig zoo hauv ntau daim ntawv thov, suav nrog lub teeb pom kev, teeb pom kev, lub koob yees duab teeb pom kev zoo, thiab tswb tswb.
Photocells yog tsim los ntawm cov ntaub ntawv xws li cadmium sulfide, cadmium selenide, los yog silicon uas muaj photoconductivity.Photoconductivity yog lub peev xwm ntawm cov khoom siv los hloov nws cov hluav taws xob conductivity thaum raug lub teeb.Thaum lub teeb tawm tsam ntawm qhov chaw ntawm lub photocell, nws tso tawm cov hluav taws xob, uas ua rau cov dej ntws ntawm cov xov tooj ntawm tes.
Photocells tuaj yeem siv ntau txoj hauv kev los tswj cov hluav taws xob hluav taws xob.Piv txwv li, lawv tuaj yeem siv los hloov lub teeb thaum tsaus ntuj thiab hloov nws thaum nws rov qab teeb.Lawv kuj tuaj yeem siv los ua lub sensor los tswj qhov ci ntawm lub vijtsam zaub lossis tswj kev ceev ntawm lub cev muaj zog.
Photocells feem ntau siv rau sab nraum zoov siv vim lawv muaj peev xwm tiv taus ib puag ncig hnyav xws li huab cua kub, av noo, thiab UV hluav taws xob.Lawv kuj tseem pheej yig, ua rau lawv muaj txiaj ntsig zoo rau ntau daim ntawv thov.
Hauv kev xaus, photocells yog ntau yam thiab siv dav hauv kev lag luam hluav taws xob.Lawv muaj kev tsim kho yooj yim thiab tus nqi qis, ua rau lawv muaj kev xaiv nrov rau ntau daim ntawv thov, suav nrog lub teeb pom kev, teeb pom kev, lub koob yees duab teeb ntsuas, tswb tswb, thiab lwm yam.
