IoT-Based Smart Control and Protection System for Home Appliances

Internet connectivity has become an essential aspect of the 21st century. Internet of Things (IoT) has embedded devices, including various sensors, software, and appliances. IoT-based intelligent home automation system offers the automated monitoring, operation, and control of home appliances via the internet. This paper presents an IoT-based, intelligent control and protection system for home appliances using NodeMCU and Blynk app. System control and operation via the app are independent of the Wi-Fi network’s nature. It eliminates additional coding to connect the system to any Wi-Fi network rather than home Wi-Fi. Moreover, it automatically detects and protects home appliances from damage against overheating, overloading, gas leakage, and fire hazards. Furthermore, the dimmer circuit offers fan speed and light intensity control. The system also provides a time-scheduling option and voice command control via Google Assistant. Above all, it saves energy and enhances human comfort.
