Peb txhua tus paub lub sijhawm koj nyob hauv chav da dej thiab poob teev. Los yog koj tsis paub tias huab cua yuav zoo li cas hnub no … lwm yam iav tsom iav tuaj yeem pab tau. Rau kuv qhov haujlwm kuv tau ua qhov me me ntawm daim iav ntse kom txuag qee qhov chaw hauv chav dej. Koj tuaj yeem pom huab cua, teev, hnub, qhov chaw, qhov kub thiab txias nyob ntawm nws. Kuj tseem muaj lub vev xaib txuas rau nws qhov uas koj tuaj yeem pom tag nrho cov ntaub ntawv hauv kab duab thiab hloov xim ntawm LED sawb.

Kauj Ruam 1: Cov Cheeb Tsam Koj Xav Tau

Nov yog cov npe ntawm cov khoom koj xav tau.

• Raspberry Pi zaub 5inch
• Raspberry Pi 3 b+
• 8GB micro sd
• Raspberry Pi muab 5.1V/2.5A
• Digitale RGB Ledstrip WS2801
• DHT11 kub thiab av noo sensor
• Ntoo
• Kho vajtse los kho cov ntoo (kua nplaum & pom)
• HDMI kab
• PIR (tsab ntawv tsa suab sensor)
• DS18B20 (ntsuas kub)

Kauj Ruam 2: Teeb Raspberry Pi

Cia peb pib los ntawm kev txhim kho qee cov software.

• WinSCP
• Win32 disc tus tswj hwm
• MobaXterm
• VNC saib
• MySQL Workbench

Ua ntej koj nruab Win 32. Thaum koj tau teeb tsa Win 32 koj tuaj yeem pib txhim kho cov duab ntawm pi.

Thaum koj qhib yeej 32 koj yuav pom tias daim nplaub tshev tuaj yeem xaiv. Xaiv koj daim npav micro sd (sab saum toj sab xis) thiab nyem rau sau (hauv qab). Kev teeb tsa yuav siv sijhawm me ntsis. Lub caij no koj tuaj yeem nruab tag nrho lwm cov software.

Thaum koj daim duab raug teeb tsa, koj tuaj yeem tso koj daim npav SD rau hauv koj tus pi thiab txhawb koj lub zog. Txuas koj tus pi nrog lub xov tooj cua ethernet rau koj lub khoos phis tawj/laptop tom qab qhov no koj pib mobaXterm. Mus rau ntu => SSH => thiab sau cov ntaub ntawv hauv qab no (saib duab kom ntxaws). Nrog rau qhov no koj nkag mus rau koj tus pi ntawm kev sib txuas ssh ntawm chaw nres nkoj 22 nrog lub npe siv "dp-siv r" thiab tus password "dp-user".

Kauj Ruam 3: Txuas Koj Tus Pi rau Koj WIFI

Yog tias koj txuas nrog koj pi koj tuaj yeem teeb tsa koj li wifi nrog cov kauj ruam hauv qab no.

sudo raspi-teeb tsa

1. Mus rau cov kev xaiv network
2. Nkag mus rau wi-fi
3. Sau koj lub npe network
4. Sau koj tus password

Tam sim no koj tau nkag mus rau koj li wifi thiab tuaj yeem hloov kho koj tus pi nrog cov cai hauv qab no.

sudo apt hloov tshiab

sudo apt hloov tshiab -y

Qhov no ua kom ntseeg tau tias koj tus pi tau hloov kho tshiab.

Kauj ruam 4: Kho vajtse

Tam sim no koj tus pi tau npaj txhij tag koj tuaj yeem pib teeb tsa Circuit. txuas raws li hais saum toj no schematics koj Circuit. Koj yuav pom tias mcp3008 tau siv. Koj tsis xav tau qhov no, qhov no yog qhov txuas rau lub vijtsam. Cov kab ntawv coj muaj lub moos, Mosi, GND thiab 5V.

Kauj ruam 5: SQL- Database

Lub sijhawm los tsim cov ntaub ntawv. Qhib koj lub mariaDB ib puag ncig ntawm koj tus pi nrog cov lej hauv qab no.

Ua ntej koj tsim tus neeg siv nrog:

CREATE USER 'mct'@'%' IDENTIFIED BY 'mct';

tom qab ntawd koj paub tseeb tias nws muaj txhua txoj cai:

ZOO TSHAJ PLAWS YOOJ YIM RAU *. * TO 'mct'@'%' Nrog GRAND OPTION;

Qhov kawg tab sis tsis tsawg kawg, koj yaug txhua yam:

NTSEEG NTAWV QHOV TSEEB;

Tam sim no rov pib qhov kev pabcuam:

sudo kev pabcuam mysql rov pib dua

Qhib mysql Workbench. Ua qhov txuas tshiab. Yog xav paub ntxiv saib daim duab.

Tam sim no qhib ntshuam, ntshuam cov ntaub ntawv thiab ua raws txoj cai.

Kauj Ruam 6: Code rau Daim iav

Qhib pyCharm thiab mus rau qhov chaw => Tsim, Exixution, Deployment => xa tawm. Nias qhov ntxiv thiab ntxiv SFTP (saib duab).

Tam sim no koj tsuas yog rub cov lej los ntawm kuv github thiab qhib nws hauv pycharm.

Kauj Ruam 7: Lub Vev Xaib

Txhawm rau muab lub vev xaib rau koj tus pi, ntxiv cov cai hauv qab no rau koj pi.

sudo apt-tau nruab intache apache2-y

Txhawm rau nkag mus ua tus neeg siv dp:

sudo chown dp-user: hauv paus *

Txhawm rau nkag mus rau daim nplaub tshev thiab ntxiv cov ntaub ntawv rau nws.

sudo chown dp-user: hauv paus/var/www/html

Qhib WinSCP. Tsim kev sib kho tshiab thiab sau cov ntawv raws li pom hauv daim duab.

Xaiv koj cov ntaub ntawv thiab rub lawv mus rau koj/var/www/html nplaub tshev.

Kauj ruam 8: Pib Pib App.py

Txhawm rau pib koj app.py cia li mus rau koj lub crontab thiab ntxiv cov lej no:

sudo crontab -e

Hauv qab ntawm cov ntawv, sau cov cai hauv qab no (piav qhia hauv daim duab).

@reboot python3 /var/www/html/app.py

Ctrl + x kom tawm thiab y nkag mus txuag.

Kauj Ruam 9: Ua Case

Lub tswv yim yog qhov yooj yim Kuv coj qhov loj me ntawm kuv lub vijtsam, qhov ntev ntawm kuv lub khob cij thiab qhov loj me ntawm kuv tus pi ua lub qhov nyob hauv qab kom tso PIR rau hauv.

Vim tias koj siv lub hdmi cable yuav tsum muaj lwm daim uas yuav tsum muaj rau koj.

Kauj ruam 10: Kuv vam tias koj nyiam nws

Kuv vam tias koj txaus siab rau daim iav ntse ntse.

Hmoov zoo!
