TUTORIAL PEMROGRAMAN ARDUINO – Sistem Monitoring dan Alarm Suhu Serta Kelembapan Kamar Bayi ESP32 DHT22 Blynk IoT WOKWI<\/p>\n\n\n\n

Pada bagian ini akan dibahas pembuatan sistem monitoring dan alarm suhu serta kelembapan kamar bayi menggunakan mikroprosesor ESP32, sensor DHT22, dan sistem Internet of Things (Iot) dengan Blynk IoT, serta software simulasi WOKWI. Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1. Suhu dan kelembapan akan diukur menggunakan sensor DHT11 dan ditampilkan pada LCD. Pada kondisi tertentu lampu LED akan menyala pada kondisi tertentu.<\/p>\n\n\n\n
