I-DIY Kit Electronic Voltmeter Ammeter - Kala I-Voltage futhi Yamanje Kalula

I-DIY Kit Electronic Voltmeter, i-Ammeter Digital Voltage Current Meter 4 Bits Single-Chip Training Parts Production DC 2.4-5.5V (10006450)

I-DIY Kit Electronic Voltmeter Ammeter iyisisetshenziswa esisebenziseka kalula futhi esisebenziseka kalula esikuvumela ukuthi ulinganise kokubili amandla kagesi namanje kumasekhethi kagesi. Ngemiyalo yayo ekulula ukuyilandela kanye nezingxenye ezifakiwe, le kit ye-DIY ilungele abathanda ukuzilibazisa nge-elekthronikhi nabathandi be-DIY abafuna ukwakha eyabo i-voltmeter ne-ammeter. Isibonisi se-LCD sinikeza ukufundwa okunembile, kuyilapho ububanzi obulungisekayo bukuvumela ukuthi ulinganise ama-voltage ahlukahlukene kanye namazinga amanje. Noma ngabe ungumuntu osaqalayo noma uyi-DIYer enolwazi, le DIY Kit Electronic Voltmeter Ammeter iyithuluzi okufanele ube nalo lanoma iyiphi iphrojekthi ye-elekthronikhi.

Incazelo: Imitha kagesi kanye neyamanje. Ingasetshenziswa njenge-voltage yedijithali evame ukusetshenziswa kanye nemitha yamanje.

Isici: 1).Ibanga likagesi lika-2.4-5.5V lingasebenza. 2) .Umklamo wesifunda uthuthukile futhi uyasebenza, futhi intengo iphezulu kakhulu. 3).Ithuthukiswa ngohlobo olusha lwe-single-chip microcomputer futhi inemisebenzi enamandla.

Ipharamitha: 1).Igama Lomkhiqizo: I-Voltage kanye Nemitha Yamanje 2).I-Volking Voltage: DC 2.4V-5.5V 3).MCU:PMS132B 4).Izinga Lokushisa Lokusebenza:-25℃~85℃ 5).Umswakama Womsebenzi:5%~95%RH 6.5)Usayizi wePCB:

Isimiso Sokujikeleza: 1).Isici esiyinhloko sesekhethi i-single-chip microcomputer PMS132B enomsebenzi wokuguqulwa kwe-analog kuya kwedijithali. I-JP1 kusekethe iyitheminali yokuphakela amandla yangaphandle. Amandla angaphandle athunyelwa ku-voltage ezinzile ye-Threminal 78M05 nge-VD1 ukuze inikeze isekethe nge-voltage yokusebenza engu-5V. 2).I-voltage elinganisiwe iwukufaka okuvela kuphinikhodi yesi-2 ye-JP2, futhi ngemva kokuthi u-R1, RP2 no-R2 bakha uchungechunge lwe-voltage ehlukanisayo, inikeza isignali yesampula ye-voltage yephinikhodi ye-14 ye-chip IC2. 3).Nweba ububanzi besilinganiso se-voltage izikhathi ezingu-11 (0-30V).Uma i-voltage elinganisiwe ingekho ngaphansi kuka-5V, futhi umthamo wokulayisha ungekho phezulu, ungakwazi ukufinyeza iphedi i-HP2, ukuze i-JP1 ingaxhunywa kugesi ohlukile. I-voltmeter yaba "isistimu yezintambo ezimbili." 4).Umthamo wamanje okaliwe uwukufaka okuvela kuphinikhodi yesi-3 ye-JP2. Ngokuvamile, i-HP1 idinga ukuba ifinyezwe, ukuze umthamo wamanje okaliwe uzodlula ku-R1 naku-RP2, futhi ugesi owenziwe uzothunyelwa kuphinikhodi ye-15 ye-IC2 ukuze ilinganiswe, futhi inani lamanje liyabalwa. 5).Uma isetshenziselwa ukulinganisa kwamanje kokunemba kokuzitholela ugesi olawulwayo, i-R1 ayidingi ukufakwa ngenxa yokuthi isixhasi samanje sesampula sifakiwe.
