Photocell
Mudziyo unoona chiedza.Inoshandiswa kumifananidzo yemamita emwenje, otomatiki on-at-dosk magetsi emumugwagwa uye mamwe maapplication-anobatika, photocell inosiyanisa kuramba kwayo pakati pematerminal ayo maviri zvichienderana nenhamba yemafotoni (mwenje) yaanogamuchira.Inonziwo "photodetector," "photoresistor" uye "light dependent resistor" (LDR).
Iyo photocell's semiconductor material inowanzonzi cadmium sulfide (CdS), asi zvimwe zvinhu zvinoshandiswawo.Photocells uye photodiodes zvinoshandiswa kune zvakafanana zvikumbiro;zvisinei, iyo photocell inopfuura ikozvino bi-directionally, nepo photodiode iri unidirectional.
Photodiode
Sensor yechiedza (photodetector) inobvumira ikozvino kuyerera kune rimwe divi kubva kune rimwe divi kuenda kune rimwe kana inobata mafotoni (chiedza).Kuwedzera chiedza, kuwedzera ikozvino.Inoshandiswa kuona chiedza mumasensa ekhamera, optical fibers uye mamwe maapplication-light-sensitive applications, photodiode inopesana nechiedza chinobudisa diode (ona LED).Photodiodes inoona chiedza uye rega magetsi aende;Ma LED anogamuchira magetsi uye anoburitsa chiedza.
Masero eSolar Anonzi Photodiodes
Solar maseru mafotodiode anobatwa nemakemikari (doped) zvakasiyana pane iyo photodiode inoshandiswa sechinja kana relay.Kana maseru ezuva akarohwa nechiedza, yavo silicon zvinhu zvinonakidzwa kune imwe nyika iyo diki yemagetsi ikozvino inogadzirwa.Mazhinji arrays e solar cell photodiodes anodiwa kusimbisa imba.
Phototransistor
Transistor inoshandisa chiedza kwete magetsi kuita kuti magetsi afambe kubva kune rimwe divi kuenda kune rimwe divi.Inoshandiswa mumhando dzakasiyana-siyana dzinoona kuvapo kwechiedza.Phototransistors inosanganisa photodiode uye transistor pamwe chete kuti ibudise yakawedzera kubuda kupfuura iyo photodiode yega.
Photoelectric
Kushandura mafotoni kuita maerekitironi.Kana chiedza chikavhenekerwa pasimbi, maerekitironi anoburitswa kubva mumaatomu ayo.Iyo yakakwira frequency yechiedza, ndipo panowedzera simba reerekitironi rinoburitswa.Photonic sensors emarudzi ese anoshanda pamusimboti uyu, semuenzaniso photocell, uye photovoltaic cell mudziyo wemagetsi.Dzinonzwa chiedza uye dzinoita kuti magetsi afambe.
kuvaka
photocell ine chubhu yegirazi yakabviswa ine maviri electrode emitter uye muunganidzi.iyo emitter yakaita semi-hollow cylinder.nguva dzose inochengeterwa pakugona kwakaipa.muunganidzi ari muchimiro chesimbi tsvimbo uye yakagadziriswa paaxis ye semi-cylindrical emitter.muunganidzi anogara achichengetwa pane zvakanaka zvingaita.iyo girazi chubhu inoiswa pane isiri-simbi base uye mapini anopiwa pachigadziko chekunze kubatana.
wokring
iyo emitter yakabatana kune isina kunaka terminal uye muunganidzi akabatana kune yakanaka terminal yebhatiri.mwaranzi yenguva zhinji kupfuura chikumbaridzo frequency yezvinhu zve emitter inoitwa chiitiko pane emitter.foto-emission inoitika.mafoto-maerekitironi anokwezvwa nemuunganidzi izvo zvakanaka wrt emitter saka ikozvino inoyerera mudunhu.kana kusimba kwechiitiko mwaranzi ichiwedzerwa iyo photoelectric ikozvino kuwedzera.
Yedu vamwe photocontrol application mamiriro
Basa rekuchinja photocell nderekuona mazinga echiedza kubva kuzuva, wobva wabatidza kana kudzima mafixtures avanosungirirwa nawo.Iyi tekinoroji inogona kushandiswa munzira dzakawanda, asi mumwe wemienzaniso yakajairika ingave marambi emumugwagwa.Kutenda kune photocell sensors uye switch, ese anogona kubatidzwa nekudzimwa otomatiki uye akazvimiririra zvichienderana nekuvira kwezuva uye kubuda kwezuva.Iyi inogona kuve nzira yakanaka yekuchengetedza pamagetsi, kuve neatomatiki kuchengetedza mwenje kana kungoita kuti marambi egadheni ako avhenekere nzira dzako husiku pasina kuabatidza.Kune nzira dzakawanda dzakasiyana dzekushandisa mafotocell kune mwenje wekunze, zvekugara, zvekutengesa kana zveindasitiri zvinangwa.Iwe unongoda chete kuve neiyo imwe photocell switch ine waya kuita dunhu kuti ugone kudzora zvese zvigadziriso, saka hapana chikonzero chekutenga switch imwe parambi.
Kune akawanda akasiyana marudzi ephotocell switch uye zvidzoreso, ese akakodzera mamiriro akasiyana uye akasiyana perks.Iyo iri nyore switch yekukwira ingave stem inokwira mafotocell.Iyo swivel controls zvakare iri nyore kwazvo kuisa asi inopa kuwedzera kuchinjika.Twist-Lock mafotocontrols akanyanya kuoma kuisa, zvisinei iwo akanyanya kusimba uye akavakwa kuti amire kuvhitavhita uye zvidiki zvinokanganisa pasina kutyora kana kukonzeresa kubatanidza mudunhu.Bhatani mafotocells anonyatso kuenderana nemwenje wekunze, akagadzirirwa kuve nyore kugadzika danda.
