WiFi-Enabled Home Automation System with Device & Switch Control and Signal Extension

Problem:

Conventional home electrical systems lack remote control, automation, and consistent connectivity across all areas, especially in environments with weak WiFi coverage.

Approach:

Designed and implemented a smart home automation system enabling remote control of electrical devices and switches, combined with a WiFi repeater module to ensure reliable connectivity across extended spaces.

System Design:

• Microcontroller-based control unit for device automation
• Relay modules for switching electrical appliances
• WiFi communication layer for remote access and control
• Mobile/web interface for user interaction
• Integrated WiFi repeater to extend network coverage and maintain connectivity

Key Contributions:

• Built a WiFi-enabled system to remotely control household devices and switches
• Integrated relay-based switching mechanisms for safe and reliable operation
• Developed communication workflows for real-time device control over network
• Implemented a WiFi repeater setup to improve signal strength and system reliability
• Designed user interaction flow for simple and intuitive control
• Tested and optimized system performance across varying network conditions

Constraints & Tradeoffs:

• Network reliability and latency affecting real-time control
• Electrical safety considerations for relay-based switching
• Signal attenuation in larger or multi-room environments
• Balancing system responsiveness with power and hardware limitations
