IoT BASED MULTICONTROLLED SMART HOME AUTOMATION AND PROTECTION SYSTEM

Abstract

The IoT Based Multicontrolled Smart Home and Protection System is designed to provide complete monitoring, automation, and protection of household electrical loads over the internet. The system allows users to operate electrical and electronic appliances using smartphones, computers, infrared remote, manual switches, and voice commands through AI assistants such as Google Home. The project is implemented using ESP32 as the central controller, which integrates various sensors and modules. A DHT11 sensor is used for temperature and humidity monitoring, while an MQ-2 smoke sensor ensures safety by activating a buzzer during fire or smoke detection. Electrical loads such as lights and fans are controlled through a relay module. The system supports multi-control operation, ensuring both flexibility and user convenience. Overall, this smart home system demonstrates a low-cost, flexible, and efficient IoT-based solution for modern household automation and safety. It reduces energy consumption by enabling intelligent monitoring and switching of loads, while ensuring fire protection and AI-based control. This work highlights the potential of IoT and AI integration in creating safer and smarter living environments.
