Phau ntawv qhia no muaj tag nrho cov ntaub ntawv koj xav tau los tsim lub peev xwm zoo, lub hnab ntim qhov ntsuas.

Kauj Ruam 1: Teeb Cov Kev Xav Tau

Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm peb DIY huab cua ntsuas qhov ntsuas, peb xav tau nws los ua:

  • Hnab me me
  • Roj teeb-powered
  • Muaj qhov them nqi hluav taws xob suav nrog
  • Txuas nrog USB
  • Txuas nrog WiFi thiab Bluetooth
  • Nyeem tau nrog nrog OLED npo
  • Hauv qab $ 100

Peb xav kom peb lub hnab tshos ntsuas qhov ntsuas kom ntsuas tau:

  • Kub
  • Siab
  • Vaum
  • CO2 qib uas cuam tshuam rau lub hlwb ua haujlwm
  • TVOC (huab cua zoo) qib kom pab nyab xeeb nyob ib puag ncig lub tshuab luam ntawv 3d

Kauj Ruam 2: Sau Cov Khoom

Rau txoj haujlwm no, koj yuav xav tau ob peb yam. Tus nqi tag nrho yog $ 82.57 thaum lub sijhawm sau ntawv

  • 1 x Yam Ntxiv - ESP32 WROOM (https://www.sparkfun.com/products/14689)
  • 1 x Lithium Ion Battery - 2Ah (https://www.sparkfun.com/products/13855)
  • 1 x Micro OLED Breakout (https://www.sparkfun.com/products/14532)
  • 1 x Environmental Combo Breakout - CCS811/BME280 (https://www.sparkfun.com/products/14348)
  • 1 x Standoffs Yas 4-40; 3/8 "(https://www.sparkfun.com/products/10461)
  • 1 x Ntsia Hlau - Phillips Lub taub hau 4-40; 1/4 "(https://www.sparkfun.com/products/10453)
  • 2 x Qwiic Cable - 50mm (https://www.sparkfun.com/products/14426)

Koj tseem yuav xav tau:

  • Ib lub tshuab luam ntawv 3D, Kuv siv MonoPrice Mini Delta 3D tshuab luam ntawv (https://www.monoprice.com/product?p_id=21666)
  • 3D tshuab luam ntawv filament, Kuv siv PLA
  • Philips lub taub hau ntsia hlau
  • Sau cov ntawv yas rau lub ntsej muag pob tshab
  • Cov ntsia hlau loj los txuas rau lub phaj ntsej muag pob tshab

Kauj Ruam 3: Luam Ntawv 3D

3D Luam Ntawv Cov Ntaub Ntawv

Feem ntau, koj yuav tsum tsim koj tus kheej lub tshuab luam ntawv 3D. Hmoov zoo, Kuv tau tshaj tawm 3D luam ntawv cov ntaub ntawv ntawm Thingiverse: https://www.thingiverse.com/thing:3545884. Nyob rau hauv tag nrho, nws siv 4 iterations kom tau mus rau qhov kawg tsim.

Kuv siv cov chaw hauv qab no los luam qhov tsim:

  • 0.2 hli txheej siab
  • 20% ntxiv
  • Tsis muaj txaj nplaum txheej

Kauj ruam 4: Sib dhos

Ua ntej tshaj, muab qhov kev tsis pom zoo tso rau 6 lub qhov me me hauv qhov thaiv.

Thib ob, ntxig lub roj teeb nruab nrab ntawm qhov sawv ntsug. Nws yuav haum rau hauv qab ntawm cov laug cam.

Thib peb, ntsia hlau hauv cov khoom siv hluav taws xob. Yog tias qhov kev siv tsis raug cai raug siv, USB chaw nres nkoj yuav tsum ua kab zoo nrog lub qhov nyob hauv qhov thaiv.

Plaub, txuas cov khoom siv hluav taws xob ua ke. Tom qab ntsaws lub roj teeb rau lub microcontroller, siv QWIIC cables txuas lub sensor thiab cov zaub hauv koob.

Thaum kawg, txiav ib daim ntawv me me ntawm cov yas rau lub ntsej muag pob tshab. Laum qhov kom haum rau ob qhov loj sib dhos hauv qhov thaiv thiab tom qab ntawd txuas nrog cov ntsia hlau ntev dua.

Ntau dua li kev ua haujlwm los ntawm kos, Kuv xav kom koj rub kuv tus lej los ntawm cov chaw cia khoom txuas hauv qab no.

Cov chaw cia khoom:

Tam sim no, cov cai:

  • Nyeem cov ntaub ntawv los ntawm txhua lub sensor
  • Xam tus nqi hloov pauv
  • Qhia cov ntaub ntawv ntawm OLED zaub
  • Txuas rau WiFi thiab qhia cov ntaub ntawv ntawm lub vev xaib tsim tawm (ntawm IP chaw nyob tso tawm ntawm lub vijtsam)

Txhawm rau program microcontroller, koj yuav tsum:

  1. Rub tawm Arduino IDE (https://www.arduino.cc/en/Main/Software)
  2. Teeb Arduino IDE thiab USB tsav tsheb (https://learn.sparkfun.com/tutorials/esp32-thing-p…)
  3. Rub tawm lub tsev qiv ntawv rau lub ntsuas hluav taws xob thiab OLED siv Arduino IDE tus thawj tswj tsev qiv ntawv
  4. Txuag koj li WiFi SSID thiab tus password rau hauv cov laug cam "nyiam"

Kauj Ruam 6: Kev txhim kho yav tom ntej

Nov yog qee cov tswv yim los txhim kho txoj haujlwm:

  1. Siv WiFi xa cov ntaub ntawv mus rau ThingSpeak lossis lwm qhov kev pabcuam los teeb nws
  2. Ntsuas lub roj teeb qhov hluav taws xob thiab tso tawm sijhawm ntxiv
  3. Siv WiFi txhawm rau rub tawm cov ntaub ntawv huab cua, xov xwm, thiab txhua yam uas lub ntse saib yuav tso tawm
  4. Ntxiv lub tswb yog tias CO2 qib siab dhau
  5. Ntxiv lub tswb yog TVOC qib siab dhau

Nco tseg: #4 yuav yog txoj hauv kev txaus kom nyob nyab xeeb hauv qhov chaw nyob thiab #5 muaj feem xyuam rau 3D cov neeg siv tshuab luam ntawv zoo li kuv tus kheej!
