Capacitive av-cov ntsuas dej noo noo yog txoj hauv kev zoo los tshuaj xyuas cov dej hauv av hauv koj cov ntoo cog, vaj, lossis tsev cog khoom siv Arduino, ESP32, lossis lwm lub microcontroller. Lawv zoo dua rau qhov kev tiv thaiv kev soj ntsuam feem ntau siv hauv DIY cov haujlwm. Saib cov vis dis aus los ntawm Andreas Spiess rau kev piav qhia zoo ntawm lawv ua haujlwm li cas. Lub peev xwm ntsuas hluav taws xob tsuas yog kwv yees li $ 1 txhua qhov ntau, txawm li cas los xij, lawv tau nthuav tawm cov khoom siv hluav taws xob thiab tsis muaj dej tsis haum. Ib qho av noo noo uas tsis tuaj yeem ntub tau tsis muaj txiaj ntsig zoo. Cov lus qhia no qhia koj yuav ua li cas txhawm rau tiv thaiv koj lub ntsuas cua siv cov nplaum ua kom sov ua kom sov, cov khoom siv me me, thiab cov cuab yeej ib txwm muaj.

Khoom siv

Qhov:

  1. Capacitance av noo sensor, piv txwv los ntawm eBay, lossis los ntawm DFrobot
  2. Teeb liab hlau (tsawg kawg 3 tus neeg ua haujlwm), 22 -24 ntsuas; peb siv xov tooj xaim los ntawm Lowes; nws yog cov tub ntxhais 4-tus neeg xyuas pib yog li ib lub xov hlau tsis siv.
  3. Adhesive-lined Polyolefin Heat-shrink tubing hauv peb qhov ntau thiab tsawg: 1/4 ", 1/2" thiab 3/4 "diam. Nrog tsawg kawg 3: 1 ntsws.
  4. Laquer lossis ntsia thawv xim: peb siv Sally Hansen Hard li Nails los ntawm Lub Hom Phiaj

Cov Cuab Yeej:

  1. Hlau Cutter (yaug style)
  2. Hlau Stripper
  3. Phom Kub
  4. Soldering hlau thiab solder
  5. Arduino lossis lwm lub microcontroller yog tias koj xav ntsuas lub ntsuas ua ntej thiab tom qab sib dhos

Nco tseg: Yam khoom txawv tshaj plaws hauv qhov kev tsim no yog qhov loj diam. tshav kub ntsws tubing nrog nplaum. Cov cua sov ntsws tuaj yeem npaj tau los ntawm ntau tus neeg muag khoom. Nws tseem nyob ntawm eBay, yog li koj tuaj yeem yuav koj cov cua sov ntsws thaum koj yuav koj cov av noo noo. Ib zaug ntxiv, nws yuav tsum tau lo rau kab thiab muaj qhov sib piv 3: 1.

Qee lub sijhawm tsis tshua muaj, peb tau pom ntau pawg ntawm cov ntsuas no uas muaj qhov tsis zoo (peb tau txais qhov kev xaj tsis zoo los ntawm Ali Express). Kuv yuav ua qhov kev sim yooj yim ntawm cov ntsuas nrog Arduino ua ntej kev tiv thaiv dej. Muaj ntau qhov kev qhia hauv web - ntawm no yog piv txwv.

Kauj ruam 2: Tshem tus Txuas

Tshem tus Txuas
Tshem tus Txuas

Tshem tawm qhov txuas nrog lub tshuab txiav tawm. Tom qab tshem qhov txuas, yuav muaj peb qhov siv tsis tau siv los ntawm lub qhov rau txuas cov kab hluav taws xob (lawv tsis tuaj yeem pom kom txog thaum koj tshem lub txuas)

Kauj Ruam 3: Npaj Cov Teeb Meem Hlau thiab Cov laug rau Sensor
