Ang proyektong ito ay nilikha bilang isang pagsubok para sa ibm iot cloud. Gumagamit kami ng isang esp-8266 upang magpadala at tumanggap ng data papunta at mula sa cloud ng ibm. Ang komunikasyon sa pagitan ng esp at cloud ng ibm ay nangyayari sa pamamagitan ng MQTT.

Upang hawakan ang lahat ng data at upang maipakita ang gumagamit sa isang interface ng gumagamit ginagamit namin ang node-red. Napaka-friendly ng baguhan.

Upang makapagsimula kailangan mo:

• Esp-8266
• dht 11/22 temp / kahalumigmigan sensor
• photosensitive diode (pagsukat ng ilaw)
• buzzer
• ground moisture sensor
• ibm cloud account

Hakbang 1: Ikonekta ang Iyong Mga Sensor

Tulad ng nabanggit namin bago gagamitin namin ang esp8266 upang mabasa at magpadala ng data ng sensor. Para sa tutorial na ito ay ipagpapalagay namin na alam mo kung paano ikonekta ang iyong mga sensor sa iyong micro controller. Kailangan mo ring malaman kung paano mag-upload ng code sa isang esp8266.

Ang aming modelo ng esp ay mayroon lamang isang analog port kaya pinili naming makatanggap ng impormasyon sa analog mula sa aming light sensor dahil maaari naming subaybayan kung gaano karaming ilaw ang nakukuha ng halaman.

Ang lahat ng iba pang mga sensor ay konektado sa digital. Ang aming sensor ng DHT11 ay nagpapadala ng data nang digital at ginagamit namin ang dht library upang bigyang kahulugan ang data ng mga sensor.

Sa itaas maaari kang makahanap ng isang circuit diagram para sa mga sensor na ginamit namin. Ngunit mangyaring tandaan na ang mga sensor na ginamit namin ay madalas na may isang module upang madali mong ikonekta ito sa iyong micro controller nang walang lahat ng labis na resistors na isinama namin sa diagram.

Hakbang 2: Code

Ito ang ginamit na sketch ng arduino. Maaari mong malaman ang tungkol sa kung paano gumagana ang code kung nabasa mo ang mga komento.
