Project Overview
Designed and implemented a comprehensive home automation system focused on energy efficiency and user convenience. The system utilizes the ESP32 microcontroller to manage various household appliances remotely via a web interface.
Problem Statement
Inefficient energy usage in residential buildings leads to higher utility costs and increased carbon footprint. Existing solutions are often expensive or lack customization for specific user needs.
Methodology
- Hardware: ESP32 Microcontroller, Relay Modules, Current Sensors (ACS712), Temperature Sensors (DHT11).
- Software: C++ (Arduino IDE), Blynk IoT Platform for mobile control.
- Communication: Wi-Fi (MQTT Protocol).
Key Features
- Remote Control: Toggle appliances from anywhere using a smartphone app.
- Automated Scheduling: Set timers for lights and fans to operate only when needed.
- Energy Monitoring: Real-time tracking of power consumption with visual graphs.
- Voice Control Integration: Compatible with Google Assistant and Amazon Alexa.
Outcome
The prototype demonstrated a potential reduction in energy consumption by approximately 15% in simulated test scenarios. The system successfully managed multiple loads with a response time of under 200ms.
