Twilight switch

**Twilight switch** ni igice cya elegitoronike kigena ko urumuri rwaka  ku buryo bwikora igihe urumuri rusanzwe rw'akazi (nk'urwa joro cyangwa izuba) rugabanutse mu gace runaka. Mu mubare munini w'imikoreshereze, ibisanzwe ni ugushoboza gucana mu mihanda, imihanda, umuhanda munini, imihanda, ubusitani, imbuga, nibindi, mugihe urumuri rwizuba rumanutse munsi y'urwego runaka (urugero: kuva nimugoroba). 

Umuzunguruko wubatswe na twilight switch, mubihe bimwe na bimwe, bisaba ibindi bice, nka relay cyangwa abahuza, mugihe ushaka kugenzura ingufu z'amashanyarazi zisumba izindi (amatara, ibikoresho byamashanyarazi, nibindi).

## Ibiranga tekinike
Hifashishijwe icyuma gikoresha urumuri ( Photoresistor, Photodiode, Phototransistor, nibindi) byerekana ingano yumucyo umurikira ibidukikije, itera uruziga rw'amashanyarazi rufungura cyangwa rugafunga imikoranire yumurongo wa mashini cyangwa ya reta ikomeye. ( power transistor, thyristor, triac, nibindi), ikora sisitemu yo kumurika. Mubisanzwe, itara risanzwe rijya k'umurongo wifotozi rikoreshwa, hamwe ningaruka zitara rihita ryaka n imugoroba kandi rihora rizima mu mucyo wa mbere w'umuseke. Turashimira iyi sisitemu, ingero nini zingero zikoreshwa zarakozwe, kuva kumurika haba ahantu rusange cyangwa abikorera ku giti cyabo kugeza kwigana kuboneka, aho twilight switch itanga imikorere yigihe gito cy'umuzunguruko. itara ryo kwigana abantu badahari kumubiri. 

Hariho uburyo bwinshi kandi bushya bwo guhanga udushya butuma urumuri rwizuba rwinshi, hamwe nogushobora guhindura urwego kugirango uhindure umuriro kurwego runaka rwumwijima, bityo ushireho gutinda no kuzimya kubijyanye nurumuri rwibidukikije. Hari ndetse moderi (modules) zidatuma urumuri rw'ubukorano (urumuri rukoresha amashanyarazi) rwaka,kandi zishobora  gutandukanya urumuri rusanzwe (urumuri rw'izuba) n'urwo bukoraho. Ariko, mu bindi bihe, bishobora kuba byiza kubihuza n'uburyo bwo gupanga igihe (time scheduling systeems) kugira ngo bikore neza kurushaho. 

## Amashanyarazi

Ikoreshwa rya twilight ikunze gukoreshwa cyane ni ubwoko bwa electronique, butandukanye nubwa elegitoronike hifashishijwe ibyuma bya pilote bimaze kwinjizwa mu muzunguruko ubwawo, kandi bigatuma imizigo mito ihuzwa mu buryo butaziguye (urugero, itara rimwe). Twilight switch iraboneka muburyo butandukanye kugirango ihuze ibikenewe byose. Mubyukuri, zirashobora gutandukana uhereye kumiterere yabafite itara kugeza kumasanduku atandukanye (silindrike, kare, nibindi). 

Witondere umubare wamatara akoresha igikoresho nimbaraga zayo muri watts, ukurikize amabwiriza mumfashanyigisho yumukoresha, kugirango wirinde ibintu biremereye bikabije kuri konte ya disiki ya disiki, mubyukuri, niba bikenewe imitwaro myinshi, hagomba gushyirwaho umuhuza. Kumuri kumuhanda, kurugero, icyerekezo cya twilight kugiti cye kirashobora gukoreshwa, cyangwa icyerekezo cyo hagati gikora andi matara ya kure kugirango ucane amatara menshi, kuburyo umutwaro urumuri rwagati rwagati rugomba kwihanganira arirwo rupapuro rwihariye rwa relaire. 

## Ibyiza
Inyungu nyamukuru yo gukoresha twilight switch ni imbaraga nyinshi zo kuzigama izana, ihujwe no korohereza gahunda idakenewe, igenga neza izuba.

## Ibibi
Ingaruka nyamukuru yo gukora installation ni uko uramutse ushyize urumuri rwububiko hafi yifoto-yerekana ifoto, switch ntishobora gufungura. Muri iki gihe, ugomba kwitondera aho amatara aherereye kubijyanye na fotodetekeri . Kandi, uzirikane ko gutwika gushingiye gusa kumubare wumucyo usanzwe uhari kandi ntabwo ushingiye ku burebure bwizuba, bityo "gutwika udashaka" bishobora kubaho, kurugero imbere yibicu byijimye bifitanye isano no kugabanuka gukabije kumucyo wibidukikije kuri sensor (urugero, mugihe hari umuyaga). Kugirango wirinde ibi, twilight switch irashobora guhuzwa hamwe na sisitemu yo guteganya igihe.
