Hauv qhov kev qhia no, koj yuav tsim lub ntsuas cua uas saib xyuas huab cua kub, av noo thiab siab, txhua tus siv Blynk, esp32, DHT22 thiab BMP180.

Khoom siv

• esp32 Microcontroller
• TSH 22
• NPE 180

Kauj ruam 1: Teeb Blynk

Koj yuav xav tau Blynk rau txoj haujlwm no kom koj tuaj yeem pom cov txiaj ntsig hauv lub sijhawm tiag tiag nyob txhua qhov chaw hauv ntiaj teb. Koj tuaj yeem pom yuav teeb tsa Blynk hauv kuv qhov kev qhia yav dhau los.

Kauj ruam 2: Nruab Lub Tsev Qiv Ntawv

Thawj lub tsev qiv ntawv koj yuav tsum tau teeb tsa yog SparkFun RHT03 Arduino Library, koj tuaj yeem rub tawm qhov no los ntawm https://learn.sparkfun.com/tutorials/rht03-dht22-humidity-and-temperature-sensor-hookup-guide?_ga= 2.53575016.1755727564.1559404402-688583549.1496066940#tsev qiv ntawv-teeb tsa. Tom qab rub tawm nws qhib Arduino IDE thiab nkag mus rau Sketch> suav nrog Tsev qiv ntawv> Ntxiv. ZIP Library … thiab xaiv cov ntaub ntawv.zip koj nyuam qhuav rub tawm.

Lub tsev qiv ntawv thib ob uas koj xav tau los teeb tsa yog Adafruit BMP085 Lub Tsev Qiv Ntawv, koj tuaj yeem teeb tsa qhov no los ntawm kev mus rau hauv Sketch> suav nrog Lub Tsev Qiv Ntawv> Tswj Cov Tsev Qiv Ntawv… tom qab ntawd tshawb rau 'BMP085'.

Kauj Ruam 3: Txhim Kho Cov Hluav Taws Xob

Tam sim no koj yuav tsum tau xaim lub Circuit Court, nws yog ib qho yooj yim Circuit Court. Saib cov duab hluav taws xob saum toj no.

Kauj Ruam 4: Tsim Daim Ntawv Thov rau Blynk

Koj yuav xav tau daim ntawv thov hauv Blynk kom koj tuaj yeem tau txais cov ntaub ntawv thiab muab nws qhia rau koj hauv app, duab. Txhawm rau tsim nws siv cov duab saum toj no.

Widgets:

• 2x Gaug
• 1x Kab rov tav

Kev ntsuas qhov ntsuas kub:

• Lub Npe: Kub
• Xim: Txiv kab ntxwv/daj
• Cov tswv yim: V5 0-100
• Daim ntawv lo: /tus pin /° C.

Lub sijhawm ncua sijhawm tshiab: 1sec

Qhov Chaw Ntsuas Cov Ntsuas:

• Lub Npe: Vaum
• Xim: Lub teeb xiav
• Tswv yim V6 0-100
• Label: /tus pin /%
• Lub sijhawm ncua sijhawm tshiab: 1sec

Cov Qib Siab Siab

• Lub Npe: Siab
• Xim: Txiv kab ntxwv/daj
• Cov tswv yim: V7 950-1050
• Tig Axis: Tawm
• Lub sijhawm ncua sijhawm tshiab: 1sec

Kauj ruam 5: Upload Code

Tam sim no peb tau npaj rau txoj cai. Ua ntej xa cov cai koj yuav tsum tau hloov qee qhov, nrhiav kab char auth = "YourAuthToken"; thiab hloov YourAuthToken nrog Auth Token koj tau sau ua ntej thiab yog tias koj siv wifi nrhiav kab char ssid = "YourNetworkName"; thiab hloov YourNetworkName nrog koj lub npe network thiab nrhiav kab kab hla = "YourPassword"; thiab hloov YourPassword nrog koj tus password Wifi. Tom qab ua qhov no tam sim no koj tuaj yeem xa cov cai.

Kauj ruam 6: Tiav lawm

Ua tau zoo, tam sim no kev ua haujlwm tau tiav thiab tam sim no tuaj yeem tso rau hauv qhov chaw uas nws tau siv zog thiab yuav xa cov ntsuas kub, av noo thiab cov ntaub ntawv siab rau koj lub xov tooj!
