Voltage Monitor rau Cov Hluav Taws Xob Hluav Taws Xob: 3 Cov Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Hauv phau ntawv qhia no kuv yuav piav qhia rau koj li cas kuv tsim kuv lub roj teeb ntsuas hluav taws xob rau kuv lub tshuab hluav taws xob ntev. Mount nws txawm li cas los xij koj xav tau thiab txuas tsuas yog ob lub xov hlau rau koj lub roj teeb (Gnd thiab Vcc). Phau ntawv qhia no xav tias koj lub roj teeb hluav taws xob ntau dua 30 volt, uas yog qhov siab tshaj qhov siab tshaj ntawm "Mini Digital Volt Meter" txuas hauv qab no. Txawm li cas los xij, qhov ntsuas hluav taws xob no hauv phau ntawv qhia no yuav raug hloov kho kom nws tuaj yeem ntsuas qhov ntsuas hluav taws xob ntau dua 30 volt.

Ua ntej tshaj, koj yuav xav tau cov hauv qab no:

• Mini Digital Volt Meter (Banggood)
• 1k Ω resistor (Cov khoom siv Banggood)
• 3k Ω resistor (Cov khoom siv Banggood)
• Cov cuab yeej siv cuab yeej
• Thaum Tshav Kub Kub Ntsws Tube (Cov Khoom Siv Banggood)
• Tej zaum rab yaj phom

Kauj Ruam 1: Hloov kho "Mini Digital Volt Meter" los daws qhov Voltages> 30 V

30 V "src ="/cuab tam/img/pixel-p.webp

30 V "src =" {{file.large_url | ntxiv: 'pib = webp & thav duab = 1 & qhov siab = 300' %} ">

Qhov "Mini Digital Volt Meter" thaum xa tawm yuav muaj ob lub xov hlau, Vcc thiab Gnd. Kev ntsuas yog ntsuas ncaj qha los ntawm Vcc xaim thiab yuav nyob ntawm qhov ntau ntawm ~ 2 txog ~ 30 volt. Ua ntawv thov qhov siab dua yuav ua rau lub nti puas tsuaj yog li tsis txhob ua nws. Txawm li cas los xij, lub nti tuaj yeem hloov kho yooj yim los ntsuas qhov hluav taws xob los ntawm ib lub xov hlau (0 - 100 V) thiab siv los ntawm lwm qhov (~ 2 - 30 volt).

Txhawm rau ua qhov no, koj yuav xav tau cov hlau txuas thiab tej zaum tus pincer. Ua ntej tshaj, tshem tawm qhov me me 0 Ω resistor uas tau qhia hauv daim duab. Qhov no yog ua kom sov cov laug ntawm ob sab thaum khoov thiab ntswj nws. Qhov thib ob, ntxiv xaim thib peb, uas tau qhia hauv daim duab.

Ua tiav! Tam sim no lub nti muaj peb lub xov hlau, ib qho rau hauv av, ib qho rau lub zog thiab ib qho rau ntsuas.

Kauj Ruam 2: Ntxiv "Voltage Divider Circuit"

Okey, yog li tam sim no koj muaj lub nti nrog peb lub xov hlau. Kev ntsuas ntau yog 0 txog 100 V thiab ntau lub zog yog kwv yees li 2 txog 30 V. Tam sim no peb yuav tsum xav tias koj yuav ntsuas qee yam siab dua, cia peb hais tias, 30 V. Tshaj li koj yuav tsis tuaj yeem siv lub zog nti ncaj qha los ntawm lub zog siv yam tsis muaj kev pheej hmoo ua rau nws puas tsuaj. Ntawm qhov tod tes, koj yuav tsis xav tau lub zog thib ob los muab qhov hluav taws xob tsuas yog rau qhov nti me me ntawm thaj tsam ntawm 2 txog 30 V. Cov tshuaj yog siv qhov hu ua "Voltage Divider Circuit" raws li pom hauv daim duab. Hauv daim duab muaj 50 V roj teeb uas yuav tsum ntsuas. Siv qhov ntsuas hluav taws xob faib hluav taws xob, ib tus tuaj yeem ua lub zog ntsuas los ntawm 12.5 V thaum ntsuas 50 V.

Qhov siab dua qhov ntsuas hluav taws xob uas koj yuav ntsuas, qhov siab dua qhov muaj zog ntawm cov resistors yuav tsum yog tam sim no ntws los ntawm cov resistors nce nrog siv qhov hluav taws xob. Kev nce tus nqi tiv thaiv yuav txo qhov tam sim no.

Nrhiav qhov tseeb qhov ntsuas tus nqi rau koj rooj plaub yog ua tau zoo tshaj plaws los ntawm kev sim. Hauv kuv rooj plaub nrog kuv 38 V roj teeb, Kuv pom tias 1000 Ω resistor li R1 thiab 1800 Ω resistor rau R2 tau ua qhov dag.

Cov hluav taws xob faib hluav taws xob tuaj yeem ua tiav txoj cai ntawm cov kab hluav taws xob thiab tom qab ntawd muab qhwv rau hauv cov cua kub ntsws kom tiv thaiv.

Kauj Ruam 3: Mounting "Mini Digital Volt Meter"

Cov kauj ruam no txawv ntawm txhua rooj plaub tab sis kuv yuav xav tias kuv qhia koj li cas kuv tau teeb tsa kuv li ntawm kuv daim ntawv ntev. Tsuas yog rau kev tshoov siab:) lub thooj yas dawb yog kev cai ua kom haum rau sab hauv lub qhov (socket) los ntawm lub tsheb thauj khoom ntev, 3D luam tawm hauv ABS. Kuv tau ua cov yas kom haum cov ntsuas hluav taws xob kom nruj, tab sis ua kom ntseeg tau tias qhov ntsuas hluav taws xob muaj 1 hli sab laug kom haum nrog cov yas sab saud. Txhawm rau tiv thaiv cov zaub ntawm qhov ntsuas hluav taws xob Kuv nchuav qee cov Epoxy txhawm rau sau 1 hli hollow yog cov zaub yog. Hauv ib ntawm cov duab koj tuaj yeem pom qee qhov kev xav ntawm txheej epoxy nyob rau sab saum toj ntawm cov zaub.
