Txoj haujlwm no tau tsim los ua kev sim rau ibm iot huab. Peb siv tus esp-8266 xa thiab txais cov ntaub ntawv mus thiab los ntawm ibm huab. Kev sib txuas lus ntawm esp thiab ibm huab tshwm sim los ntawm MQTT.

Txhawm rau daws txhua cov ntaub ntawv thiab nthuav qhia tus neeg siv nrog tus neeg siv cuam tshuam peb siv node-liab. Nws yog tus pib zoo heev.

Txhawm rau pib koj xav tau:

• Esp-8266
• dht 11/22 ntsuas kub/noo noo
• photosensitive diode (ntsuas lub teeb)
• buzzer
• av noo sensor
• ibm cloud account

Kauj Ruam 1: Txuas Koj Cov Sensors

Raws li peb tau hais ua ntej peb yuav siv lub esp8266 los nyeem thiab xa cov ntaub ntawv sensor. Txog qhov kev qhia no peb yuav xav tias koj paub yuav txuas koj lub ntsuas pa li cas rau koj lub micro tswj. Koj kuj tseem xav paub yuav ua li cas xa cov lej xa mus rau esp8266.

Peb tus qauv esp tsuas muaj ib qho chaw nres nkoj sib piv yog li peb tau xaiv kom tau txais cov ntaub ntawv analog los ntawm peb lub teeb pom kev vim tias tom qab ntawd peb tuaj yeem saib xyuas lub teeb pom kev ntau npaum li cas.

Tag nrho lwm cov sensors tau txuas nrog digitally. Peb DHT11 sensor xa cov ntaub ntawv digitally thiab peb siv lub tsev qiv ntawv dht los txhais cov ntaub ntawv ntsuas.

Saum toj no koj tuaj yeem pom daim duab qhia chaw rau cov ntsuas peb tau siv. Tab sis thov nco ntsoov tias cov ntsuas uas peb siv feem ntau tuaj nrog tus qauv yog li koj tuaj yeem yooj yim txuas nws mus rau koj lub micro tswj yam tsis muaj txhua qhov txuas ntxiv uas peb suav nrog hauv daim duab.

Kauj ruam 2: Code

Nov yog daim duab arduino peb tau siv. Koj tuaj yeem kawm paub txog txoj cai ua haujlwm li cas yog tias koj nyeem cov lus.
