Infrared Receiver

Mutu wolandila wa infrared ndi cholandirira chophatikizika chopangidwa ndi chubu cholandirira cha infrared ndi ma amplifier circuit. Dera la amplifier nthawi zambiri limapangidwa ndi midadada ndi ma capacitor angapo okana, ndipo imayenera kupakidwa mubokosi lotchingira lachitsulo. Choncho, derali ndi lovuta kwambiri, koma voliyumuyo ndi yaying'ono. Nthawi zambiri, pali njira ziwiri zosiyanitsira ma pini amutu omwe amalandila ma infrared: 1. Iiaka ula YachiPart Yachiwoneaka yunpamaigwiriKhaysatirakPart gaaka amulpe. Makasitomala amatha kusiyanitsa zikhomo za infuraredi wolandila mutu molingana ndi bukhu lofotokozera; 2. Ndiko kuyesa kwa multimeter Kukaniza kwa zikhomo ziwirizo, pezani imodzi yokhala ndi mtengo wotsutsa pang'ono pazikhomo ziwirizo. Osasuntha cholembera. Gome lofiira limalumikizidwa ndi VCC ndi piritsi lakuda. Pini ina ndi pini yolumikizira. Zikhomo zitatu za mutu wolandira infrared ndi GND, VCC, OUT 3 pini, iliyonse yomwe ili pansi, mphamvu ndi kutulutsa chizindikiro. Zitsanzo za mitu yolandira infrared ndizosiyana, ndipo zikhomo zawo ndizosiyana. Kupindula kwa amplifier mkati mkati mwa wolandila infrared ndi yayikulu kwambiri, ndipo ndikosavuta kuyambitsa kusokoneza. Chotero. Mitu yolandila ma infrared: Mitu yolandila ma infrared nthawi zambiri imalandila, kukulitsa, ndi kutsitsa mitu. Nthawi zambiri “0 ”Ndi “1 ”Kusiyanaku kumawonekera nthawi zambiri muutali wa mlingo kapena kuzungulira kwa chizindikiro. Pamene single -chip microcomputer decodes, kulandira chamutu linanena bungwe phazi zambiri chikugwirizana ndi kusokoneza kunja kwa single -chip microcomputer. Chofunika kwambiri ndikupeza deta “0 ”Ndi “1 ”Kusiyana kwa ma waveforms. Mapeto otulutsa amatha kulumikizidwa ndi mabwalo amagetsi a CMOS ndi TTL. Mtundu woterewu wolandila mutu umagwiritsidwa ntchito pazida zapakhomo monga ma air conditioner, ma TV, ma VCD.
