ESP32 Project: IOT Irrigation System
IOT Irrigation System adalah projek yang memantau bacaan pH, moisture, temperature, flame dan water level dalam tapak tanaman. Projek ini juga boleh mengawal empat relay berdasarkan bacaan input.
Relay 1 akan dihidupkan apabila water level rendah. Relay 2 akan dihidupkan apabila moisture rendah. Relay 3 akan dihidupkan apabila mengesan api (flame). Relay 4 akan dihidupkan apabila ph terlebih asid atau terlebih alkali.
Paparan bacaan ini boleh dilihat di web http://shahrulnizam.com/iot/irrigation.php serta paparan pada mobile apps.
Skematiknya adalah seperti berikut.
PCB komponen layout nya adalah seperti berikut.
