Xyoo 2020, lub ntiaj teb ntsib cov dab tsis pom hu ua Corona Virus. Tus kab mob no ua rau tib neeg mob thiab tsis muaj zog. Coob leej neeg poob lawv qhov zoo.

Muaj teeb meem loj thaum xub thawj, qhov teeb meem yog qhov tsis muaj peev xwm ntawm cov cuab yeej siv kho mob zoo li lub ntsuas saib xyuas cov ntshav cov pa oxygen, lub tshuab ua pa & tshuaj tua kab mob. Hauv lub sijhawm xav tau no, peb xav tias peb tuaj yeem pab txhua tus los qhia lawv yuav ua li cas thiaj ua DIY Ntshav Ntshav Ntshav Ntshav Ntshav. Cov Lus Qhia no tau mob siab rau cov tub rog, kws kho mob & txhua tus neeg ua haujlwm hauv tsoomfwv uas tau pab peb thoob plaws xyoo 2020.

Kauj Ruam 1: Sau Cov Khoom

Txhua yam ntaub ntawv hais los ntawm no yooj yim muaj nyob hauv koj lub khw lag luam nrog rau cov khw hauv online.

1. Esp32 Wroom 32D
2. Max 30102 Oximeter Sensor
3. BreadBoard
4. Jumper Cables
5. Blynk App hauv smartphone

Kauj ruam 2: Taw qhia

Nov yog DIY phiaj xwm los tsim kev daws teeb meem hauv tsev rau kev saib xyuas cov ntshav oxygen qib ntawm tus kheej. Tus nqi ntawm qhov haujlwm no tsawg dua 15 $.

Lub hauv paus tseem ceeb ntawm txoj haujlwm no yog:

Max30102 Oximeter Sensor: MAX30102 yog kev sib xyaw mem tes oximeter thiab lub plawv dhia saib biosensor module. Nws suav nrog cov liab LED thiab cov duab hluav taws xob LED, lub tshuab ntsuas hluav taws xob, cov khoom siv kho qhov muag, thiab lub suab qis hluav taws xob hluav taws xob nrog cov teeb pom kev ib puag ncig. - MAX30102 nta 1.8V fais fab mov thiab cais 5.0V fais fab rau sab hauv LEDs rau lub plawv dhia thiab ntshav oxygen tau txais hauv cov cuab yeej siv tau, hnav ntawm cov ntiv tes, pob ntseg, thiab lub dab teg.

Peb yuav txuas peb lub ntsuas nrog ESP32 pawg thawj coj saib kom nkag mus & qhia pom cov pa oxygen nyob hauv Blynk app ntawm peb lub xov tooj.

Kauj Ruam 3: Ua Kev Sib Txuas

Muaj ob peb qhov sib txuas nkaus xwb, viz; (Xa mus rau kev sib txuas los ntawm daim duab hauv Circuit)

1. Txuas GND ntawm ESP board rau GND ntawm Max30102 sensor.
2. Txuas 3v3 ntawm ESP board rau Vin ntawm Max30102 sensor.
3. Txuas Pin 22 ntawm ESP board rau SDA ntawm Max30102 sensor.
4. Txuas Pin 21 ntawm ESP board rau SCL ntawm Max30102 sensor.

Thaum qhov kev sib txuas tiav tiav peb tuaj yeem txav mus teeb tsa Blynk txoj haujlwm.

Kauj Ruam 4: Teeb tsa Txoj Haujlwm hauv Blynk

Koj yuav tsum teeb tsa Blynk app ntawm koj lub smartphone. Tsim ib tus as khauj lossis nkag mus yog tias twb tsim lawm.

Ua raws cov kauj ruam:

1. Tsim txoj haujlwm tshiab & muab nws lub npe.
2. Xaiv pawg thawj coj ua ESP32 tus tsim tawm pawg thawj coj saib.
3. Tam sim no ntxiv ob lub widgets; Ntsuas & Labeled Tus Nqi.
4. Kho qhov ntsuas qhov ntsuas: Hloov tus Pin li Virtual V4 & tus nqi los ntawm 0 txog 100.
5. Kho cov ntawv sau tus nqi: Hloov daim ntawv lo ua "Ntshav Cov pa %".

Kauj Ruam 5: Cia Txoj Cai Nws

Cov cai txuas ntawm no ua tiav. Koj tsuas yog yuav tsum tau hloov qee yam raws li koj li "Blynk Auth Token" & Wifi Settings. Rub tawm nws nrog Arduino IDE.
