A photocell, inozivikanwawo se photoresistor kana light-dependent resistor (LDR), imhando yekudzivirira inoshandura kupikisa kwayo zvichienderana nehuwandu hwechiedza chinowira pairi.Kupikisa kwe photocell kunoderera sezvo kusimba kwechiedza kunowedzera uye zvakasiyana.Izvi zvinoita kuti maphotocells abatsire mukushandisa kwakasiyana-siyana, zvinosanganisira masensa emwenje, maraiti emumugwagwa, mwenje wemamita emakamera, uye maaramu embavha.
Mafotocell anogadzirwa nezvinhu zvakaita secadmium sulfide, cadmium selenide, kana silicon inoratidza photoconductivity.Photoconductivity kugona kwechinhu kushandura mabatiro ayo emagetsi kana yaiswa pachiedza.Kana chiedza charova pamusoro pe photocell, chinobudisa maerekitironi, izvo zvinowedzera kuyerera kwezvino kuburikidza nesero.
Photocells inogona kushandiswa nenzira dzakasiyana-siyana kudzora maseketi emagetsi.Semuenzaniso, anogona kushandiswa kubatidza mwenje kana kwasviba uye kudzima kana kwapenya zvakare.Iwo anogona zvakare kushandiswa se sensor kudzora kupenya kweanoratidza skrini kana kudzora kumhanya kwemota.
Photocells anowanzo shandiswa mukushandiswa kwekunze nekuda kwekugona kwavo kushingirira mamiriro ekunze akadai sekupisa kwakanyanya, hunyoro, uye UV mwaranzi.Izvo zvakare zvisingadhure, zvichiita kuti ive inodhura-inoshanda mhinduro kune akawanda maapplication.
Mukupedzisa, mafotocells ane hunyanzvi uye anoshandiswa zvakanyanya muindasitiri yemagetsi.Vane kuvaka kwakapfava uye kwakaderera, kuchivaita sarudzo yakakurumbira kune akawanda maapplication, anosanganisira mwenje sensors, mwenje wemumugwagwa, kamera mwenje metres, mbavha maaramu, nezvimwe.
