Mai karɓar Infrared

Shugaban karɓar infrared haɗin haɗin kai ne wanda ya ƙunshi bututu mai karɓar infrared da da'irar amplifier. Da'irar amplifier gabaɗaya ta ƙunshi tarin tubalan da masu ƙarfin juriya da yawa, kuma yana buƙatar haɗa shi a cikin akwatin kariya na ƙarfe. Saboda haka, kewayawa yana da rikitarwa sosai, amma ƙarar ƙarami ne. Gabaɗaya magana, akwai hanyoyi guda biyu don bambance infrared masu karɓar kai: 1. Sauƙi ita ce a ƙyale masu ba da kai da ke karɓa da infrared su ba da kalmar misali. Abokan ciniki na iya bambanta fil na infrared mai karɓar kai bisa ga ƙayyadaddun littafin; 2. Gwajin gwaji ne na multimeter Juriya na fil biyu, nemo ɗaya tare da ƙaramin juriya a cikin fil biyun. Kar a motsa alkalami. An haɗa jan tebur tare da VCC da kwamfutar hannu baki. Wani fil shine fil ɗin sigina. Fin guda uku na infrared mai karɓar kai sune GND, VCC, OUT fil 3, kowanne daga cikinsu yana ƙasa, wuta da fitarwa. Samfuran kawunan masu karɓar infrared sun bambanta, kuma fil ɗin su sun bambanta. Riba na amplifier na ciki a cikin mai karɓar infrared yana da girma sosai, kuma yana da sauƙi don haifar da tsangwama. Saboda haka. Shugaban karɓar Infrared: Kawuna masu karɓar infrared gabaɗaya suna karɓa, haɓakawa, da shuwagabannin ruɗi. Gabaɗaya “0 ”Da. “1 ”Bambanci yawanci yana nunawa a tsawon matakin ko siginar sigina. Lokacin da microcomputer guda-chip ya yanke ƙididdigewa, ƙafar fitarwar mai karɓa yawanci ana haɗa shi da katsewar microcomputer guda-chip na waje. Babban fifiko shine nemo bayanai “0 ”Da. “1 ”Bambanci tsakanin waveforms. Ana iya haɗa ƙarshen fitarwa zuwa da'irorin samar da wutar lantarki na CMOS da TTL.
