Nyob zoo cov neeg nyeem, Hauv cov lus qhia no, kuv yuav qhia koj li cas kuv tsim qhov Arduino raws li cov tshuaj ntsuas pa.
*** CEEB TOOM - Nov yog yam khoom siv uas tuaj yeem siv los tswj koj cov dej sib xyaw ua ke. Kev dhia dej yuav yog qhov txaus ntshai thiab txhua yam koj ua nrog qhov no yog ntawm koj tus kheej txoj kev pheej hmoo. ***
Cov ntawv no suav nrog ob ntu
1) Kuv yuav piav qhia tias kuv tsim lub thawv ntawv li cas, vim tias kev tsim lub voj voog ntawm lub khob cij yog ib yam, tsim cov khoom tiav yog lwm qhov.
2) Kuv yuav muab cov cai rau koj
Txhua ntu kuv siv muaj nyob ntawm Ebay, los ntawm Tuam Tshoj lossis Hong Kong.
Nov yog cov ntsiab lus ntawm qhov kuv tau siv:
- 9V roj teeb (IKEA ib qho vim kuv nyiam xim)
- 9V roj teeb txuas
- PVC thaiv.
tom qab xav ntau, Kuv pom ib qho uas lub roj teeb nkag tau thiab yog "ib txwm xauv" los ntawm nws qhov ntev
- Arduino pawg thawj coj saib
- LCD zaub
- Ob txoj kev hloov.
Ib qho rau on/off.
Thawb kom teeb cov khoom sib xyaw tshiab rau 21%. Nws yuav tsum yog "thawb thiab tso tawm"
- Ib qho pa oxygen
- Ib txoj hlua txuas koj lub ntsuas pa (ntawm no nws xaus los ntawm lub ntsaws ntsaws)
- ADS1115 hloov mV muab los ntawm lub ntsuas hluav taws xob rau cov teeb liab.
- Cov kab
Kauj ruam 1: Zaub
Cov zaub tau txuas nrog siv "Dupont" cable.
Nws tau lo rau ntawm lub npov npog
Kuv siv qee qhov "yas ua npuas ncauj" (yam khoom siv dav siv los tiv thaiv cov khoom siv hluav taws xob thaum lub sijhawm xa tawm). Kuv txiav ib feem me me ntawm nws, glued nws ntawm LCD thiab ntawm lub npov npog.
Qhov no ua haujlwm zoo heev.
Kauj ruam 2:
Lub thawv muaj ADS1115 nrog hloov millivolt rau digital teeb liab. Nws tau txuas nrog lub ntsuas hluav taws xob los ntawm lub mloog pob ntseg nkaus.
Ob lub khawm: ib qho los hloov qhov system rau/tawm.
Qhov thib ob (liab liab), ib zaug nias, yuav teeb tsa lub zog 21% cov pa.
Lub kaw lus cia li ntsuas ntawm 21% thaum pib.
*** YUAV UA LI CAS YUAV UA LI CAS - DETAILS ***
Qhov tseeb thaum tsis muaj oxygen, lub sensor xa 0mV
Thaum pib, lub kaw lus txiav txim siab nws nyob hauv 21% cov pa oxygen, ntsuas mV (cia hu nws x) muab los ntawm lub ntsuas thiab khaws nws.
Tom qab ntawd nws soj ntsuam ntawm qhov nrawm nrawm ntawm qhov muaj peev xwm muab los ntawm lub ntsuas, thiab yog li tso saib cov pa oxygen sib xws.
0 mV -> 0%
x mV -> 21%
mVV ->..
Nws tso tawm kom pom cov ntsiab lus muaj peev xwm thiab nqes hav siv rau kev suav (s =… ntawm cov zaub)
Nws ua qhov nruab nrab nrawm txhawm rau zam kev tsis pom kev thiab tuaj yeem tso saib '-' yog tias lub ntsuas yog HS.
Kuv ntxiv qhov kev txav mus los kom hloov pauv.
(Kuv tso koj kawm txoj cai rau qhov no)
Kauj Ruam 3: Thiab Arduino
Hauv qab, ib qho arduino tseem tau kaw thiab siv ncaj qha tab sis lub roj teeb 9V.
Kauj ruam 4: Thiab Tam sim no Arduino Code
Nov yog tus lej arduino: D
Kuv yuav tsum tau kho nws. tiv tauj kuv

Plug & Ua Si CO2 Sensor Zaub Nrog NodeMCU/ESP8266 rau Cov Tsev Kawm Ntawv, Lub Tsev Kawm Qib Siab lossis Koj Lub Tsev: Kuv yuav qhia koj sai npaum li cas txhim kho lub plug & ua si CO2 sensor qhov twg txhua qhov ntawm txoj haujlwm yuav txuas nrog DuPont xov hlau. Yuav muaj tsuas yog 5 cov ntsiab lus uas yuav tsum tau muab siv, vim tias kuv tsis tau muab tshuaj txhuam ua ntej qhov haujlwm no txhua lub sijhawm
