Intshayelelo
Kwitekhnoloji yanamhlanje, ii-nuances phakathi kwezixhobo ezahlukeneyo ngamanye amaxesha zinokuziva ngathi zichaza ikhowudi eyimfihlo.Namhlanje, makhe sikhanyise kwi-conundrum eqhelekileyo: umahluko phakathi kwe-photocell kunye ne-motion sensor.Ezi zixhobo zithobekileyo zidlala indima ebalulekileyo kubomi bethu bemihla ngemihla, ukanti iyantlukwano yazo isenokusibaleka.
Mhlawumbi ukhe wadibana neefotocells kunye nezinzwa ezishukumayo izihlandlo ezininzi ngaphandle kokubanika ingcinga yesibini.I-photocell, ekwabizwa ngokuba yi-photoresistor, iphendula kutshintsho ekukhanyeni, ukuguqula phakathi kokuvula kunye nokuvala amazwe.
Kwelinye icala, aisivamvo sentshukumoibona intshukumo, ivuselela iintshukumo ezisekelwe kwiimpawu zayo zokucupha.Ngokujonga nje, banokubonakala ngathi ngabazala abakude kwihlabathi leenzwa, kodwa ujonge nzulu, kwaye uya kutyhila amandla abo kunye nokusetyenziswa kwabo.
Kweli nqaku, siza kutyhila iimfihlakalo emva kwezi zixhobo zobuchwepheshe be-smart.Siza kuphonononga ukuba zisebenza njani iiseli zeefoto kunye nezinzwa ezishukumayo kunye nokuba zinegalelo njani ekusebenzeni ngokungenamthungo kobume bethu obufakwe buchwephesha.
Zisebenza Njani Iifotocell?
Photocells, ngokwenzululwazi eyaziwa ngokuba photoresistors okanyeizichasi ezixhomekeke ekukhanyeni (LDRs), zizixhobo ze-semiconductor ezibonisa iimpawu zokuxhathisa eziguquguqukayo ezixhomekeke kubukhulu bokukhanya kwesiganeko.
Kwinqanaba layo elisisiseko, aicell cellisebenza njenge-resistor ekuxhathisa kwayo imodareyitha ekuphenduleni umbane wokukhanya wesiganeko.I-paradigm yayo yokusebenza isekelwe kwi-photoconductivity eboniswe yizinto ezithile ze-semiconductor.Kwiindawo ezikhanyiswe kakuhle, izinto eziphathekayo ze-semiconductor zifumana ukunyuka kwe-conductivity ngenxa yokusebenzisana neefotoni.
Ngokuqhelekileyo, ii-photocells zibandakanya izinto ze-semiconductor, ezifakwe ngokucwangcisiweyo phakathi kwemigangatho emibini.I-semiconductor isebenza njengeyona nto iphambili esebenzayo, iququzelela ukuguqulwa kwezinto zayo zombane phambi kokukhanya.Olu lwakhiwo olunemaleko lungaphakathi kwindlu, lukhusela amacandelo angaphakathi.
Njengoko ii-photons zingqubana ne-semiconductor, zinika amandla awoneleyo kwii-electron, zibakhuthaze kumanqanaba aphezulu amandla.Olu tshintsho luphucula ukusebenza kwe-semiconductor, ikhuthaza ukuhamba lula kwangoku.
Ngokusisiseko, ngexesha lasemini, xa ukukhanya kuqaqambile, iphotocell isebenza ukunciphisa amandla, ngaloo ndlela icima izibane kwizibane zesitrato.Kwaye ngokuhlwa, amandla ayanda, ukwandisa amandla okukhanya.
Iifotocells zinokudityaniswa kwiinkqubo ezahlukeneyo zombane, ezinje ngezibane zasesitalatweni, imiqondiso, kunye nezixhobo zokubona indawo yokuhlala.Ngokusisiseko, ii-photocells zisebenza njengezixhobo zoluvo, zilungiselela iimpendulo ze-elektroniki ezixhomekeke kwiimeko zokukhanya.
Ziziphi iiSensors zeMotion?
Izinzwa ezishukumayo sisizathu sokuba izibane zakho zivuleke ngomlingo xa ungena egumbini okanye ifowuni yakho isazi ukuba ijika nini isikrini sayo.
Ngamafutshane, izinzwa ezishukumayo zizixhobo ezincinci ezithatha naluphi na uhlobo lwentshukumo kwindawo ezingqongileyo.Basebenza ngeendlela ezahlukeneyo, njengokubona utshintsho lobushushu, ukudlala ngamaza esandi, okanye nokuthatha imifanekiso ekhawulezayo yendawo.
Iindidi ezahlukeneyo zezivamvo zisebenzisa iindlela ezahlukeneyo zokubona intshukumo.Nantsi inkcazo yezo ziqhelekileyo:
