Infrared Receiver

Infrared inogamuchira musoro ndeye yakabatanidzwa inogamuchira inoumbwa ne infrared inogamuchira chubhu uye amplifier wedunhu. Iyo amplifier yedunhu inowanzo umbwa muunganidzwa wemabhuraki uye akawanda anopikisa capacitors, uye inoda kuiswa mubhokisi resimbi rinodzivirira. Nokudaro, dunhu racho rakaoma zvikuru, asi vhoriyamu iduku. Kazhinji kutaura, kune nzira mbiri dzekusiyanisa mapini emusoro ekugamuchira infrared: 1. Riri nyore nderokubvumira vagoveri vemisoro vanogamuchira infrared kugovera ruzivo rwomuenzaniso. Vatengi vanogona kusiyanisa mapini e infrared yekugamuchira musoro zvinoenderana neyakatsanangurwa bhuku; 2. Iyo multimeter bvunzo yekuyedza Kupokana kwemapini maviri, tsvaga imwe ine diki yekupikisa kukosha mumapini maviri. Usafambisa peni. Tafura tsvuku yakabatana neVCC uye piritsi dema. Imwe pini ndiyo pini yechiratidzo. Mapini matatu emusoro wekugamuchira infrared ndeye GND, VCC, OUT 3 pini, imwe neimwe ivhu, simba uye chiratidzo chinobuda. Mienzaniso ye infrared inogamuchira misoro yakasiyana, uye mapini avo akasiyana. Iko kuwana kwemukati amplifier mukati meiyo infrared inogamuchira yakakura kwazvo, uye zviri nyore kwazvo kukonzera kukanganisa. Naizvozvo. Infrared inogashira musoro: Infrared inogamuchira misoro inowanzo gamuchira, inosimudzira, uye inoderedza misoro. Kazhinji “0 ”Uye “1 ”Musiyano unowanzo kuratidzwa muhurefu hwezinga kana kutenderera kwechiratidzo. Kana iyo single -chip microcomputer yadhirodha, iyo yekugamuchira musoro inobuda tsoka inowanzobatanidzwa kune yekunze kukanganisa kweimwe -chip microcomputer. Chinonyanya kukosha ndechekutsvaga data “0 ”Uye “1 ”Musiyano pakati pe waveforms. Iyo inobuda inopera inogona kubatana neCMOS uye TTL magetsi emagetsi maseketi. Rudzi urwu rwekugamuchira musoro runowanzo shandiswa mumidziyo yemumba senge air conditioners, maTV, VCDs.
