Uyazi ngokukhanya komgwaqo okuhlakaniphile okune-PIR?
Izibani zasemgwaqweni zisizungezile, zigcina ubusuku bethu buphephile futhi bukhanya. Kodwa ubuwazi ukuthi izibani zasemgwaqweni zanamuhla zingaphezu nje kwamadivayisi okukhanyisa? Sezihlakaniphe kakhulu futhi zisebenza kahle ngenxa yedivayisi encane: i-Passive Infrared Sensor (PIR).
Umlingo Wezinzwa Ze-PIR
Izinzwa ze-PIR zifana namehlo esibani sasemgwaqweni, ezikwazi ukubona izithombe zethu ezihambayo. Lapho nje usondela esibani sasemgwaqweni esinenzwa ye-PIR ebusuku, siyavula, sikukhanyisele indlela. Uma uhamba, isibani sasemgwaqweni sizocima ngokuzenzakalelayo futhi noma sishintshele kwimodi yokukhanya okuphansi ukuze songe amandla. Lokhu kulawula okuhlakaniphile akugcini nje ngokwenza ubusuku bethu buphephe, kodwa futhi kusisiza songe amandla.
Ukuvela Okuhlakaniphile Kwezibani Zemigwaqo
Izibani zomgwaqo zendabuko zivame ukuhlala zikhanya ubusuku bonke, kungakhathaliseki ukuthi kukhona odlulayo, okungagcini nje ngokuchitha ugesi kodwa futhi kwandisa izindleko zokulungisa. Izibani zomgwaqo ezinobuchwepheshe be-PIR zihlukile kakhulu. Zilungisa ngokuzenzakalelayo ukukhanya kwazo ngokusekelwe endaweni ezungezile kanye nokuhamba ngezinyawo. Uma kungekho muntu eduze, isibani somgwaqo sizohlala sikhanya kancane, njengokungathi silala kancane. Kodwa ngokushesha nje lapho othile efika, sizovuka siphile futhi sinikeze ukukhanya okukhanyayo.
Lolu hlelo olusha oluhlakaniphile lunezinzuzo eziningi ezinhle:
Ukonga amandla nokuvikela imvelo: izibani zasemgwaqweni zikhanya kuphela uma kudingeka, okusho ukuthi zisebenzisa amandla amancane futhi zikhiqiza ukukhishwa kwekhabhoni okuncane.
Isikhathi eside sokuphila: amabhalbhu nezinye izibani zihlala isikhathi eside ngoba azisetshenziswa njalo, ngakho kuzodingeka uzishintshe kaningi.
Ukuphepha okuthuthukisiwe: Ukusabela kokukhanya ngesikhathi kusiza ukugcina abahamba ngezinyawo nabashayeli bephephile, ikakhulukazi ebusuku noma ezimweni eziphansi.
Ngakho-ke, kusebenza kanjani?
Inzwa ye-PIR iyimfihlo yokwenza konke kwenzeke. Ithola imisebe ye-infrared ekhishwa yizinto futhi itshela izibani zasemgwaqweni ukuthi zivuleke uma ibona ukunyakaza, njengomuntu noma imoto. Ngaphezu kwalokho, le nzwa isebenza kahle kuzo zonke izimo zezulu, kungaba usuku olushisayo lwasehlobo noma ubusuku obubandayo basebusika.
Ukuze uthole imiphumela emihle kakhulu, izinzwa ze-PIR zivame ukufakwa amamitha angu-2-4 ngaphezu komhlaba ukuze zimboze ibanga elifanele. Ngenxa yezindlela ezithile zokucubungula isignali eziyinkimbinkimbi kanye nosizo lwezinye izinzwa ezimbalwa, isibani sasemgwaqweni singahlunga ngempumelelo ukunyakaza okungahlosiwe njengokunyakazisa amaqabunga futhi sinciphise ama-alamu angamanga.
Uma sibheka phambili, njengoba ubuchwepheshe buqhubeka buthuthuka, inhlanganisela yobuchwepheshe be-PIR kanye nobunye ubuchwepheshe bezinzwa izokwenza amadolobha ethu ahlakaniphe. Isibonelo, izibani zasemgwaqweni zingalungisa ukukhanya kwazo ngokuzenzakalelayo ngokusekelwe ekukhanyeni okuzungezile, kanti izinhlelo zokukhanya zasemgwaqweni zingaqashwa futhi ziphathwe kude kusetshenziswa ubuchwepheshe bokuxhumana obungenantambo, okuthuthukisa ukusebenza kahle nokuthembeka.
Idolobha lesikhathi esizayo lizoba nalawa madivayisi ahlakaniphile, okungeke nje kuphela kwenze izimpilo zethu zibe ngcono kodwa futhi kusize nemvelo. Isibani ngasinye somgwaqo esinobuchwepheshe be-PIR siyisinyathelo esincane kodwa esibalulekile ekuhambeni kwentuthuko yezobuchwepheshe, futhi isinyathelo esikhulu esibheke edolobheni elihlakaniphile.
Ake sibheke phambili kulezi zibani zomgwaqo ezihlakaniphile ezikhanyisa imigwaqo eminingi futhi zisisondeze ekusaseni eliqhakazile.
