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

Hauv cov lus qhia no, kuv qhia yuav ua li cas tsim Internet-of-Things (IoT) chaw nres tsheb huab cua nrog kev saib xyuas ntawm Cov Khoom Siv Hluav Taws Xob Tsis Txaus (VOCs). Txog qhov haujlwm no, Kuv tsim Cov Khoom Ua-Nws-Koj Tus Kheej (DIY). Kho vajtse thiab software yog qhib-qhov.

Kauj Ruam 1: MeteoMex Aeria Kit

Cov khoom siv MeteoMex aeria (https://www.meteomex.com) raug nqi txog 25 USD thiab muaj

• 1 Luam Circuit Board (PCB).
• 1 BME280 kev nyab xeeb huab cua.
• 1 CCS811 VOCs sensor
• 1 Wemos D1 R1 mini ESP8266 microprocessor nrog WiFi.
• headers tus pin
• 1 Jumper (J1).

Ntxiv mus, koj yuav xav tau lub chaw nres tsheb txuas thiab lub zog tsim nyog rau lub cuab yeej ua tiav (USB lossis 3 x AA roj teeb), thiab USB cable rau kev ua haujlwm.

Kauj Ruam 2: Muab Tshuaj Txhuam Txhuam

Koj yuav tsum tau muab lub taub hau thiab lub cim tso rau ntawm PCB thiab Wemos D1 mini. Thov ua tib zoo nrog kev qhia kom raug ntawm lub ntsuas pa ntawm lub rooj tsavxwm. Txhawm rau kom ntseeg tau tias kev txhim kho kom huv, Kuv siv lub khob cij rau sib dhos cov khoom.

Kauj ruam 3: Sau npe lossis teeb tsa ThingsBoard Server

Txhawm rau siv ThingsBoard ua IoT platform, koj yuav tsum sau npe ntawm https://thingsboard.io, lossis teeb tsa koj tus kheej ThingsBoard server. Muaj ntau txoj hauv kev los txhim kho Cov Khoom Hauv Pawg Zej Zog, xws li ntawm Linux Server, Windows, Raspberry Pi thiab lwm yam Kuv tau xaiv teeb tsa ntawm Ubuntu 18.04 LTS virtual tus kheej server:

Ntawm koj li ThingsBoard piv txwv, koj yuav tsum nkag mus ua tus neeg xauj tsev thiab sau npe lub cuab yeej tshiab rau xa cov ntaub ntawv xov tooj cua. Koj lub cuab yeej yuav raug txheeb xyuas nrog nws cov cim nkag.

Hauv cov kauj ruam tom ntej, koj xav tau tus neeg rau zaub mov: chaw nres nkoj URL thiab nkag mus token ntawm koj lub cuab yeej.

Kauj Ruam 4: Ua Haujlwm Wemos D1 Mini

Wemos D1 mini tuaj yeem ua haujlwm nrog Arduino IDE.

Nruab ESP32 cov laug cam ntxiv los ntawm https://dl.espressif.com/dl/package_esp32_index.json hauv Arduino IDE thiab xaiv cov cuab yeej raug: LOLIN/Wemos D1 R1. Txwv tsis pub, koj yuav "cib" nws tas mus li (tshwm sim rau kuv..)!

Cov piv txwv sib txawv muaj nyob ntawm

Txog qhov kev qhia no, peb siv qhov program MeteoMex_USB_ThingsBoard_aeria_VOCs.

Tseem ceeb: Hauv txoj haujlwm, koj yuav tsum siv qhov URL raug ntawm koj li ThingsBoard server, thiab nkag mus rau ntawm koj lub cuab yeej!

Ntxiv mus, koj yuav tsum txhais koj li WiFi SSID thiab tus password.

Koj kuj yuav tsum txiav txim siab tus nqi piv txwv, tshaj tawm cov ntaub ntawv txhua 10 feeb (rau kev saib xyuas lub sijhawm koj tuaj yeem xa cov ntaub ntawv txhua 500 ms).

Kauj Ruam 5: Vaj Tsev Nyob Chaw Nres Tsheb

Qhov chaw ntawm koj lub chaw nres tsheb huab cua yog qhov tseem ceeb: Nws yuav tsum tau tiv thaiv los ntawm tshav ntuj ncaj qha thiab los nag. Nyob rau tib lub sijhawm, koj xav tau lub qhov tso pa txaus los ntsuas VOC thiab cov xwm txheej huab cua. Qhov zoo tshaj, koj tuaj yeem teeb tsa MeteoMex ze rau lub qhov (socket) thiab nyob hauv ntau ntawm koj li WiFi network.

Txog vaj tsev, koj tuaj yeem txiav txim siab xaiv sib txawv. Lub thawv "kws tshaj lij" tsim nyog yuav raug nqi koj ~ 10 USD, thiab koj xav tau cov yas ntau ntxiv …). Hloov chaw, Kuv rov siv lub yas yoghurt beaker yas. Tau kawg, ib qho zoo nkauj heev. Txog tam sim no, Kuv zoo siab heev nrog cov tshuaj no: Tsawg ib puag ncig hneev taw, tus nqi qis (~ 1.5 USD, suav nrog 1L ntawm yoghurt) thiab ua haujlwm tau zoo.

Kauj Ruam 6: Saib Xyuas Online

Npaj txhij Yog tias koj nyiam, koj tuaj yeem faib cov pej xeem dashboard ntawm koj lub chaw nres tsheb huab cua:

IoT chaw nres tsheb huab cua nrog VOCs, Irapuato, MX, 1, 990 m.a.s.l.
