Hauv Txoj Haujlwm no peb tau cuam tshuam DHT11 nrog nodemcu thiab tom qab ntawd peb tab tom xa cov ntaub ntawv ntawm dht11 uas yog cov av noo thiab kub mus rau phpmyadmin database.

Kauj Ruam 1: Siv Software:

1. Arduino IDE: Raws li nodemcu peb tab tom siv arduino IDE nkaus xwb. Koj tuaj yeem rub tawm qhov tseeb Arduino IDE los ntawm qhov txuas no:

www.arduino.cc/en/Main/Software

Tam sim no yuav teeb tsa nodemcu rau arduino IDE li cas, peb yuav qhia koj qhov ntawd hauv cov theem hauv qab no.

2. Kev teeb tsa XAMPP server: Ntawm no peb siv XAMPP server nws tuaj yeem siv tau ob qho tib si hauv lub qhov rais thiab Linux, tab sis kuv qhov lus pom yog tias yog koj nyob hauv Ubuntu (Txhua lub platform Linux) tom qab ntawd mus nrog LAMP. Tam sim no txij li peb nyob hauv windows yog li peb tau nyiam XAMPP server. Yog li koj tuaj yeem rub tawm XAMPP server los ntawm qhov txuas no. Ib qho ntxiv ntawm no yog cov kauj ruam rau LAMP server:

1. Nruab Apache

sudo apt-tau nruab apache2

2. Nruab MySQL:

sudo apt-tau nruab mysql-server

3. Nruab PHP:

sudo apt-tau nruab php5 libapache2-mod-php5

4. Restart Server:

sudo /etc/init.d/apache2 rov pib dua

5. Txheeb xyuas Apache https:// localhost/

koj yuav tau txais ib nplooj ntawv apache los ntawm nyem qhov txuas saum toj no yog tias koj tsis tau txais nws txhais tau tias muaj qee yam tsis raug nrog koj teeb tsa

Ntawm no peb tab tom siv PHPMYADMIN uas yog lub vev xaib sib tham ntawm MySQL server yog li txhawm rau txhim kho qhov kev siv hais kom ua:

sudo apt-tau nruab phpmyadmin

Kauj Ruam 2: Cov Khoom Siv:

1) Node MCU V3: Node MCU yog qhov qhib IOT platform. Nws suav nrog cov khoom siv uas khiav ntawm ESP8266 Wi-Fi SoC los ntawm kho vajtse uas yog raws li ESP-12 module. Lub sij hawm "Node MCU" los ntawm lub hauv paus hais txog lub firmware ntau dua li cov khoom siv dev.

2) DHT11 sensor: Qhov DHT11 Kub thiab Vaum Sensor nta qhov ntsuas ntsuas cov teeb liab tso tawm nrog qhov ntsuas kub thiab av noo lub peev xwm. Nws tau koom ua ke nrog kev ua haujlwm siab 8-ntsis microcontroller. Nws cov cuab yeej siv ua kom ntseeg tau zoo thiab ruaj khov mus sij hawm ntev zoo. Qhov ntsuas no suav nrog lub hauv paus tiv thaiv thiab lub ntsuas rau ntub NTC ntsuas cov ntsuas kub. Nws muaj qhov ua tau zoo tshaj plaws, teb tau sai, muaj peev xwm tiv thaiv kev cuam tshuam thiab ua haujlwm tau zoo.

Kauj Ruam 3: Yuav Kho Li Cas Nodemcu hauv Arduino IDE

Hauv qab no yog cov kauj ruam los teeb tsa nodemcu hauv arduino IDE

Saum toj no I1, I2 thiab I3 cov duab muaj nyob rau qhov siv uas peb yuav siv rau peb cov ntawv ua kom koj nkag siab

Kauj Ruam 1: Ua ntej koj yuav tsum qhib Arduino IDE.

Kauj ruam 2: Tam sim no nyem rau ntawm qhov nyiam tab zoo li I1 duab. Tam sim no koj yuav tsum tau luam ib qho URL hauv tus thawj tswj hwm ntxiv. Nov yog qhov URL- https://arduino.esp8266.com/stable/package_esp8266… ces nyem ok

Kauj Ruam 3: Tam sim no mus rau Cov Cuab Yeej ces xaiv Pawg Thawj Coj. koj yuav tau txais ib lub qhov rais zoo li I2.

Tsuas yog nqes mus rau ntawm lub qhov rai ntawd thiab tshawb rau esp8266 los ntawm ESP8266 Zej Zog lossis koj tuaj yeem tshawb ncaj qha esp8266 los ntawm kev ntaus ntawm qhov kev xaiv tshawb nrhiav, tam sim no nyem rau ntawm lub pob install.

Kauj ruam 4: Rov pib dua koj Arduino IDE

Kauj ruam 5: Tam sim no mus rau Cov Cuab Yeej ces Xaiv koj lub cuab yeej nodemcu raws li peb tau qhia hauv I3 duab

Kauj Ruam 4: Daim duab Circuit:

Kauj ruam 5: Code:

Koj tuaj yeem tau txais cov cai los ntawm peb Github Txuas

Kauj Ruam 6: Yees Duab:

Kev piav qhia tag nrho Txoj Haujlwm tau muab rau hauv cov vis dis aus saum toj no

Yog tias koj muaj kev tsis ntseeg txog txoj haujlwm no thov tawm lus rau peb hauv qab no. Thiab yog tias koj xav kawm paub ntau ntxiv txog kev teeb tsa kab ke koj tuaj yeem mus ntsib peb tus youtube channel

Thov mus saib thiab nyiam peb Facebook nplooj ntawv rau hloov tshiab tas li.
