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

ESP8266 cov qauv yog cov nqi qis uas sawv ib leeg tswj nrog ua hauv Wi-nkaus, thiab kuv twb tau ua tus lej Qhia Qhia txog lawv.

DTH11/DTH21/DTH22 thiab AM2301 yog qhov nrov heev ua ke Kub thiab Vaum Arduino ntsuas, thiab kuv tau ua tus lej Qhia Qhia nrog lawv ib yam nkaus, suav nrog Cov Lus Qhia ntawm Cov Ntsuas Kub Kub thiab Cov Ntsuas Ntsuas nrog 2 ESP8266 txuas ua ke ntawm lawv tus kheej ntiag tug Wi-nkaus network.

Hauv Cov Lus Qhia no kuv yuav qhia koj li cas koj tuaj yeem ua Tus Kub thiab Vaum Web Server nrog ESP8266 thiab DHT11 thiab txuas rau nws ntawm koj lub network Wi-nkaus uas twb muaj lawm los ntawm ntau yam khoom siv nrog lub vev xaib.

Kauj Ruam 1: Cheeb Tsam

1. OneNodeMCU ESP8266 board (Kuv siv NodeMCU 0.9 version, tab sis lwm yam, lossis txawm sawv ib leeg ESP-12 lossis ESP-01 yuav ua haujlwm)
2. Ib DHT11 Sensor module Kuv tau txais los ntawm qhov pheej yig 37 lub teeb ntsuas

Peb yuav tsum tau hais kom meej cov ntawv HTML uas yuav raug tsim thaum lub vev xaib siv txuas rau lub server.

Peb yuav hais qhia qhov kev sib txuas kom kaw tom qab cov ntaub ntawv kuv tau xa, thiab tseem yuav qhia tus browser kom rov qhib dua (Rov ua dua tshiab) tom qab 5 vib nas this los ntawm kev ntxiv "Refresh: 5" rau hauv daim ntawv. Txoj kev no lub vev xaib yuav rov ua dua tshiab txhua 5 vib nas this.

1. Hauv Cheeb Tsam Tsim, xaiv cov Txheej Txheem Txheej Txheem 1 (Daim Duab 1)
2. Hauv Tus Kws Tshuaj Ntsuam Xyuas xaiv cov khoom "Ntawv", thiab nyem rau ntawm "…" khawm ntawm nws tus nqi (Daim duab 1)
3. Hauv "Text" editor type: "HTTP/1.1 200 OK" "Content-Type: text/html" "Connection: close" "Refresh: 5" "" """"""" Kub: %0 "" Vaum: %1 "" "" "(Daim duab 2) %0 yuav raug hloov nrog tus nqi los ntawm AnalogElement1, thiab %1 yuav raug hloov nrog tus nqi los ntawm AnalogElement2
4. Nyem rau ntawm lub pob OK los kaw qhov kev sib tham

Kauj Ruam 8: Hauv Visuino: Txuas DHT11 Cheeb Tsam

1. Txuas tus "Kub" tso zis tus pin ntawm HumidityThermometer1 tivthaiv rau "Hauv" tus pin ntawm AnalogElement1 ntawm FormattedText1 tivthaiv (Daim duab 1)
2. Txuas "Humidity" tus pin tso tawm ntawm HumidityThermometer1 tivthaiv rau "Hauv" tus pin ntawm AnalogElement2 ntawm FormattedText1 tivthaiv (Daim duab 2)

Kauj Ruam 9: Hauv Visuino: Ntxiv thiab Txuas Ntug Ntug Ntes Sib Koom

Peb yuav tsum xa cov ntawv HTML txhua lub sijhawm muaj kev sib txuas tshiab. Ua ntej peb xa peb yuav tsum tau tos me ntsis txij li lub vev xaib yuav tsum xa daim ntawv thov ua ntej lawv cia siab tias yuav pom qhov tshwm sim. Txhawm rau ua qhov ntawd peb yuav siv Kev ncua ntu txuas nrog "Txuas" tus pin ntawm TCP/IP Server Socket.

1. Ntaus "ncua" hauv Lub Lim Lim ntawm Cov Ntawv Cuab Yeej Cuab Yeej ces xaiv qhov "Ncua Sijhawm" tivthaiv (Daim duab 1), thiab tso rau hauv thaj chaw tsim
2. Hauv Cov Khoom teeb tsa tus nqi ntawm "Interval (uS)" cov khoom rau 200000 (Daim duab 2)

3. Txuas tus "Tawm" tus pin ntawm FormattedText1 tivthaiv rau "Hauv" tus pin ntawm Delay2 tivthaiv (Daim duab 3)
4. Txuas tus "Tawm" tus pin ntawm Delay2 tivthaiv rau "Disconnect" tus pin nkag ntawm "Modules. WiFi. Sockets. TCPServer1" ntawm "NodeMCU ESP-12" tivthaiv (Duab 4)

Qhov kev tivthaiv qeeb yuav txuas lub qhov (socket) sai tom qab ntawv tau xa tuaj.

Kauj Ruam 11: Tsim, Ua Ke, thiab Tshaj Tawm Arduino Code

1. Hauv Visuino, Nias F9 lossis nyem rau ntawm lub pob uas qhia ntawm daim duab 1 los tsim Arduino code, thiab qhib Arduino IDE
2. Txuas lub NodeMCU module nrog USB cable rau lub khoos phis tawj
3. Xaiv hom pawg thawj coj thiab chaw nres nkoj raws li kuv tau qhia koj hauv Cov Lus Qhia no
4. Hauv Arduino IDE, nyem rau ntawm Upload khawm, txhawm rau sau thiab xa cov cai (Daim duab 2)

Kauj ruam 12: Thiab Ua Si …

Nrog koj zoo siab! Koj tau ua Wi-Fi Kub thiab Vaum Web Server.

Ntawm Daim Duab 1 thiab hauv Cov Duab Koj tuaj yeem pom qhov txuas thiab txhawb nqa txoj haujlwm. Kuv siv lub USB Power Bank me me los txhawb lub zog.

Nco ntsoov hauv txoj haujlwm ntawm Kauj Ruam 4 koj tau nkag mus rau qhov SSID thiab Password raug rau koj li Wi-nkaus hotspot

Yog tias koj qhib lub vev xaib ntawm koj lub khoos phis tawj lossis lub xov tooj ntawm tes, thiab ntaus:

dht11server./

Thiab nias Enter, koj yuav pom qhov ntsuas kub thiab av noo ntsuas los ntawm tus qauv. Qhov nyeem ntawv yuav rov ua dua tshiab txhua 5 vib nas this raws li teev tseg hauv Kauj Ruam 7.

Nco ntsoov ntxiv Dot tom kawg ntawm lub npe, txwv tsis pub Windows yuav tsis tuaj yeem daws cov npe sau npe

Ntawm daim duab 2 koj tuaj yeem pom daim duab Visuino tiav.

Kuj txuas nrog yog Visuino qhov haujlwm, uas kuv tau tsim rau qhov Qhia Qhia no. Koj tuaj yeem rub tawm thiab qhib nws hauv Visuino:
