Projek ini dibuat sebagai ujian untuk awan ibm iot. Kami menggunakan esp-8266 untuk mengirim dan menerima data ke dan dari awan ibm. Komunikasi antara esp dan cloud ibm berlaku melalui MQTT.

Untuk menangani semua data dan menampilkan pengguna dengan antara muka pengguna, kami menggunakan simpul-merah. Ia sangat mesra pemula.

Untuk memulakan, anda memerlukan:

• Esp-8266
• dht 11/22 sensor suhu / kelembapan
• diod fotosensitif (pengukuran cahaya)
• pembesar suara
• sensor kelembapan tanah
• akaun awan ibm

Langkah 1: Sambungkan Sensor Anda

Seperti yang telah kami sebutkan sebelumnya, kami akan menggunakan esp8266 untuk membaca dan mengirim data sensor. Untuk tutorial ini, kami akan menganggap anda tahu bagaimana menghubungkan sensor anda ke pengawal mikro anda. Anda juga perlu mengetahui cara memuat naik kod ke esp8266.

Model esp kami hanya mempunyai satu port analog sehingga kami memilih untuk menerima maklumat analog dari sensor cahaya kami kerana dengan itu kami dapat memantau berapa banyak cahaya yang diperoleh kilang.

Semua sensor lain disambungkan secara digital. Sensor DHT11 kami menghantar data secara digital dan kami menggunakan perpustakaan dht untuk mentafsirkan data sensor.

Di atas anda dapat mencari gambarajah litar untuk sensor yang kami gunakan. Tetapi perlu diingat bahawa sensor yang sering kami gunakan dilengkapi dengan modul supaya anda dapat menghubungkannya dengan mudah ke pengawal mikro anda tanpa semua perintang tambahan yang kami sertakan dalam rajah.

Langkah 2: Kod

Ini adalah lakaran arduino yang kami gunakan. Anda boleh mengetahui bagaimana kod tersebut berfungsi sekiranya anda membaca komen.
