Isamkeli se-infrared

Intloko yokufumana i-infrared ngumamkeli odibeneyo owenziwe ityhubhu efumana i-infrared kunye nesekethe yeamplifier. Isekethe ye-amplifier ngokuqhelekileyo iqulunqwe yingqokelela yeebhloko kunye ne-multiple resistance capacitors, kwaye kufuneka ifakwe kwibhokisi yokukhusela izinto zetsimbi. Ngoko ke, isiphaluka sinzima kakhulu, kodwa umthamo uncinci. Ngokubanzi, kukho iindlela ezimbini zokwahlula izikhonkwane zentloko zokufumana infrared: 1. Ilula kukuvumela ababoneleli beentloko abafumana i-infrared ukuba babonelele ngemodeli. Abathengi banokwahlula izikhonkwane zentloko yokufumana infrared ngokwencwadi yengcaciso; 2. Luvavanyo lovavanyo lwe-multimeter Ukumelana nezikhonkwane ezimbini, fumana enye enexabiso elincinci lokumelana nezikhonkwane ezimbini. Musa ukususa ipeni. Itafile ebomvu idityaniswe neVCC kunye netafile emnyama. Elinye iphini liphini lomqondiso. Izikhonkwane ezintathu zentloko yokufumana i-infrared yi-GND, VCC, OUT 3 izikhonkwane, nganye yazo ingumhlaba, amandla kunye nemveliso yesignali. Iimodeli zeentloko zokufumana i-infrared zihlukile, kwaye izikhonkwane zazo zihlukile. Inzuzo ye-amplifier yangaphakathi ngaphakathi kwe-receiver ye-infrared inkulu kakhulu, kwaye kulula kakhulu ukubangela ukuphazamiseka. Ngoko ke. Intloko efumana i-infrared: Iintloko ezifumana i-infrared zihlala zifumana, zikhulisa, kunye neentloko zokuthotywa. Ngokubanzi “0 ”Kwaye “1 ”Umahluko udla ngokubonakaliswa kubude benqanaba okanye umjikelezo wesiginali. Xa i-single-chip microcomputer icoca, unyawo olufumana i-header output ludla ngokudityaniswa nokuphazamiseka kwangaphandle kwe-single-chip microcomputer. Eyona nto iphambili kukufumana idatha “0 ”Kwaye “1 ”Umahluko phakathi kwamaza. Ukuphela kwemveliso kunokudityaniswa kwi-CMOS kunye neesekethe zokubonelela ngombane we-TTL. Olu hlobo lokufumana intloko lusetyenziswa ngokubanzi kwizixhobo zendlu ezifana ne-air conditioners, iiTV, iiVCD.
