Uma kukhulunywa ngokuxoxisana ngentengo, umthengisi okukude we-IR uthi umkhiqizo ushibhile kakhulu kanti umthengi uhlala ethi ubiza kakhulu. Noma kunjalo, izinga lenzuzo yomthengisi lingasondela ku-0% .Kunezizathu ezi-2. Noma kunjalo, akufanele sikhulume ngenzuzo kuphela kepha futhi kufanele sicabangele ubuchwepheshe. Thina esikude seYangkai kungenzeka singanikeli ngentengo ephansi kakhulu emakethe, imbangela ukuthi siqhubeka nokutshala imali ku-R & D. Ngenxa yalokhu, irimothi yethu ingcono kunezinye ezisezingeni. Ngilandele ukuqonda ubuchwepheshe obuyisisekelo be-IR kude.
Ngokuvamile, i-IR eyihlane inezingxenye ezi-2. Ingxenye eyodwa ngeyokudlulisa. Ingxenye eyinhloko yale ngxenye i-infrared emitting diode. Kuyidayidi ekhethekile lapho okokusebenza kwehlukile kunedayode ejwayelekile. Amandla wezinga elithile azongezwa emikhawulweni yomibili yedayode ukuze ivule ukukhanya kwe-IR esikhundleni sokukhanya okubonakalayo. Njengamanje, irimothi ye-IR emakethe isebenzisa idayode ehambisa ubude be-IR wave ngo-940nm. I-diode iyafana nedayode ejwayelekile ngaphandle kombala. Omunye umenzi we-IR akude angabazi kahle lobu buchwepheshe. Uma ubude begagasi le-IR lingazinzile, ukudluliswa kwesiginali yesilawuli kude kuyothinteka. Enye ingxenye eyokwamukela isiginali. I-diode yokuthola okungafakwanga iso ibamba iqhaza kulo msebenzi. Umumo wayo uyindilinga noma uyisikwele. Amandla okubuyela emuva adinga ukungezwa, noma, awakwazi ukusebenza. Ngamanye amagama, i-infrared diode diiding idinga ukusetshenziswa okuphindayo ukuzwela okuphezulu. Kungani? Ngenxa yamandla wokudlulisa aphansi wedayidi ekhipha infrared, isignali etholwe yi-infrared eyamukela diode ibuthakathaka. Ukwenza ngcono izinga lokuthola amandla, i-diode yokwamukela engafakwanga ukusetshenziswa isetshenziswe kakhulu eminyakeni yakamuva.
iphelile i-diode yokuthola i-infrared inezinhlobo ezi-2. Osebenzisa ishidi lensimbi ukuvikela isignali. Enye isebenzisa ipuleti lepulasitiki. Zombili zinezikhonkwane ezi-3, i-VDD, i-GND ne-VOUT. Ukuhlelwa kwezikhonkwane kuya ngemodeli yayo. Sicela ubheke kumiyalo enikezwe ngumenzi. Iqedile i-diode yokuthola eye-infrared inenzuzo, abasebenzisi bangayisebenzisa kalula, ngaphandle kokuhlolwa okuyinkimbinkimbi noma ukuvikelwa okuvalekile. Kepha, ngicela unake imvamisa yenkampani yenethiwekhi yedayidi.
