Isamukeli se-infrared

Ikhanda elithola i-infrared yisamukeli esihlanganisiwe esakhiwe ithubhu ethola i-infrared nesekhethi ye-amplifier. Isekethe ye-amplifier ngokuvamile yakhiwa iqoqo lamabhulokhi kanye nama-capacitor amaningi okumelana, futhi idinga ukupakishwa ebhokisini lensimbi elivikela impahla. Ngakho-ke, isifunda siyinkimbinkimbi kakhulu, kodwa ivolumu incane. Ngokuvamile, kunezindlela ezimbili zokuhlukanisa izikhonkwane zekhanda zokwamukela infrared: 1. Ilula ukuvumela abahlinzeki bekhanda abathola i-infrared ukuthi banikeze imininingwane yemodeli. Amakhasimende angakwazi ukuhlukanisa izikhonkwane zekhanda le-infrared eyamukelayo ngokuya ngebhuku lemininingwane; 2. Ukuhlola ukuhlolwa kwe-multimeter Ukumelana nezikhonkwane ezimbili, thola eyodwa enenani elincane lokumelana kumaphini amabili. Ungalisusi ipeni. Ithebula elibomvu lixhunywe ne-VCC kanye nethebhulethi emnyama. Elinye iphinikhodi yiphinikhodi. Izikhonkwane ezintathu zekhanda elamukelayo le-infrared yi-GND, VCC, OUT 3 pin, ngalinye eliphansi, amandla kanye nokuphuma kwesignali. Amamodeli amakhanda athola i-infrared ahlukile, futhi izikhonkwane zawo zihlukile. Inzuzo ye-amplifier yangaphakathi ngaphakathi kwesamukeli se-infrared inkulu kakhulu, futhi kulula kakhulu ukubangela ukuphazamiseka. Ngakho - ke. Ikhanda elamukela i-infrared: Amakhanda amukela i-infrared ngokuvamile athola, amakhanda akhulisayo, kanye namakhanda aphansi. Ngokuvamile “0 ”Kanye ne- “1 ”Umehluko uvame ukubonakala ngobude bezinga noma umjikelezo wesignali. Uma i-single-chip microcomputer iqopha, unyawo oluphumayo lukanhlokweni ngokuvamile luxhunywa ekuphazamisekeni kwangaphandle kwe-single -chip microcomputer. Okubalulekile okuphezulu ukuthola idatha “0 ”Kanye ne- “1 ”Umehluko phakathi kwama-waveforms. Isiphetho esiphumayo singaxhunywa kumasekhethi kagesi we-CMOS kanye ne-TTL. Lolu hlobo lokwamukela ikhanda luvame ukusetshenziswa ezintweni zasendlini ezifana nama-air conditioner, ama-TV, ama-VCD.
