Moamoheli oa infrared

Hlooho e amohelang infrared ke seamoheli se kopaneng se entsoeng ka tube e amohelang infrared le potoloho ea amplifier. Potoloho ea amplifier hangata e entsoe ka pokello ea li-blocks le li-capacitor tse ngata tsa ho hanyetsa, 'me e hloka ho kenngoa ka lebokoseng le sireletsang thepa ea tšepe. Ka hona, potoloho e thata haholo, empa molumo o monyenyane. Ka kakaretso, ho na le mekhoa e 'meli ea ho khetholla lithapo tsa hlooho tse amohelang infrared: 1. 蕞 Simple is to allow infrared receiving head suppliers to provide model specifications. Bareki ba ka khetholla lithakhisa tsa hlooho e amohelang infrared ho latela buka ea litlhaloso; 2. Ke tlhahlobo ea tlhahlobo ea li-multimeter Ho hanyetsa ha lithakhisa tse peli, fumana e nang le boleng bo fokolang ba ho hanyetsa lithakong tse peli. U se ke ua sisinya pene. Tafole e khubelu e hokahane le VCC le letlapa le letšo. Pini e 'ngoe ke pini ea matšoao. Lithakhisa tse tharo tsa hlooho e amohelang infrared ke GND, VCC, OUT 3 pins, e 'ngoe le e 'ngoe ea tsona e le fatše, matla le tlhahiso ea pontšo. Mefuta ea lihlooho tsa ho amohela li-infrared e fapane, 'me lithakhisa tsa tsona li fapane. Phaello ea amplifier e ka hare ka hare ho mokelikeli oa infrared e kholo haholo, 'me ho bonolo haholo ho baka tšitiso. Ka hona. Hlooho e amohelang infrared: Lihlooho tse amohelang infrared hangata li amohela, ho holisa le ho theola lihlooho. Ka kakaretso “0 ”le “1 ”Phapang hangata e bonahala ka bolelele ba boemo kapa potoloho ea matšoao. Ha single -chip microcomputer e khetha, leoto le tsoang ho hlooho e amohelang hangata le hokahanngoa le tšitiso ea kantle ea microcomputer e le 'ngoe. Ntho ea bohlokoa ka ho fetisisa ke ho fumana data “0 ”le “1 ”Phapang pakeng tsa maqhubu a maqhubu. Qetello ea tlhahiso e ka hokahanngoa le li-circuits tsa phepelo ea motlakase tsa CMOS le TTL. Mofuta ona oa hlooho ea ho amohela hangata o sebelisoa lisebelisoa tsa ntlo tse kang air conditioner, TV, VCDs.
