Txhua qhov txhia chaw muaj qhov tshwm sim loj ntawm Tus Kab Mob Tshiab Corona (COVID19). Nws tau dhau los tsim nyog los saib xyuas qhov xwm txheej tam sim no ntawm COVID-19 hauv Ntiaj Teb.

Yog li, nyob hauv tsev, qhov no yog txoj haujlwm kuv xav txog "Ntiaj Teb Nyob Covid19 Dashboard"-Lub Dashboard uas muab cov lus qhia tseeb txog lub sijhawm COVID-19 lub ntiaj teb. Tsis tas yuav tsum khaws TV hauv lossis saib hauv ntau lub vev xaib.

Qhov tsim ntawm txoj haujlwm tsis yog qhov tseem ceeb. Tab sis ua qee yam muaj txiaj ntsig, siv cov khoom siv uas yooj yim yog qhov nyuaj. Txoj haujlwm no yuav pab koj tsim qhov yooj yim dashboard interface kom koj hloov kho tshiab.

Khoom siv

• ESP8266
• OLED Zaub
• Jumper Cables

Kauj Ruam 1: Schematics:

Kauj ruam 2: Teeb:

1. Mus ntsib Realtime Covid19 Dashboard's Website. Nov Kuv Siv

2. ID nkag mus/Sau npe mus rau https://thingspeak.com. Mus rau App thiab Tsim Tshiab ThingHttp Action.

   • Muab Lub Npe Koj Xaiv, URL (https://trackcorona.live), Txoj hauv kev tau txais thiab hauv Parse String, koj yuav tsum muab XPath los ntawm trackcorna.live lub vev xaib ntawm thaj chaw xav tau uas koj xav qhia.

   • Hauv Qhov Piv Txwv Zoo Dua (Duab), Kuv Parsing String For Confirmed Cases, txhua yam koj yuav tsum ua yog

     • Txoj Cai Nyem rau Tus Naj Npawb Ntawm Tus Kheej> Txheeb Xyuas,
     • Ib zaug ntxiv Right Click in the Code> Copy> CopyXPath
     • Muab qhov no tso rau hauv Parse String field ntawm ThinkHttp Action thiab Txuag Nws.
     • Ib yam nkaus, ua qhov no rau txhua qhov Rov Qab Los, Tuag, Tus Neeg Tuag Tuag thiab Tus Tuag Tus Nqi.
     • Mus ntsib Tus Txheej Txheem Cai thiab Hloov SSID nrog koj Lub Npe Wifi, Tus Kheej nrog Koj Tus Kheej Wifi thiab Tus lej API nrog koj li ThingHttp API.
3. Upload Cov Cai. Qhov ntawd yog !!

Kauj ruam 4: Ua haujlwm:

Ua cov kev sib txuas raws li daim duab qhia chaw thiab xa cov lej tom qab xaiv lub rooj tsav xwm kom raug thiab COM Port. Yog tias nws qhia qhov ua yuam kev kom ntseeg tau tias koj tau ntxiv lub tsev qiv ntawv raws li cov lus qhia tau hais los saum no.

Yog tias nws siv sijhawm ntau los khiav ntawm OLED, Xyuas kom tseeb tias koj tau txuas nrog rau cov kev pabcuam internet piv txwv li Koj li WiFi lossis Hotspot.
