IoT-Based Energy Monitoring System

An IoT-Based Energy Monitoring System is a smart solution designed to monitor and control energy usage remotely. Using an ESP32 Dev Module, a Four-Channel Relay Module, Regulator, Power Supply, and Current Sensor, this system enables real-time monitoring and control of connected devices via a web application. The web application interface displays energy usage data and allows users to turn devices on or off, optimizing energy management and enhancing safety.

Components:

1. ESP32 Dev Module: Acts as the central microcontroller with built-in WiFi and Bluetooth capabilities, enabling wireless communication and data transmission.
2. Four-Channel Relay Module: Controls the power to four different appliances, allowing each to be independently turned on or off based on commands from the ESP32.
3. Current Sensor (ACS712): Measures the current passing through each connected device to monitor energy consumption in real-time.
4. Regulator: Ensures the system receives stable voltage, protecting components from voltage fluctuations.
5. Power Supply: Provides reliable power to the ESP32 and relay module, often using a USB power supply or a regulated 5V/12V adapter.
6. Web Application: Serves as the user interface for displaying real-time data, including power consumption for each device, and provides control options for toggling each relay.

System Architecture:

• Data Collection: The current sensor connected to each appliance measures the current flow, and the ESP32 reads this data, calculating energy consumption.
• Data Processing: The ESP32 processes the sensor data and sends it over WiFi to the web application.
• Control: The web application receives data from the ESP32, displays it, and allows users to control each relay via the user interface.
• Real-Time Monitoring: Users can view live energy consumption and control devices remotely, helping them manage energy use more effectively.

Web Application Features:

• Live Data Display: Real-time updates on current and energy consumption for each appliance.
• Relay Control Buttons: Switch devices on or off directly from the interface.
• Energy Usage History: Records historical data to analyze patterns and optimize usage.
• Alerts and Notifications: (Optional) Sends alerts if power usage exceeds predefined thresholds, helping to prevent overloads.

Benefits:

• Efficient Energy Management: By monitoring and controlling device usage, the system helps reduce unnecessary energy consumption and cost.
• Remote Control: Allows users to manage appliances from any location, improving convenience and safety.
• Data-Driven Insights: The web application logs and displays usage patterns, aiding in more informed energy decisions.

Applications:

• Home and Office Energy Monitoring: Manages appliances such as lights, heaters, fans, and computers to reduce energy bills.
• Industrial Automation: Controls heavy machinery and monitors energy consumption, leading to safer and more efficient operations.
• Smart Grid Integration: Contributes to load management in smart grid systems by controlling peak power usage.
