IoT-Based Solar & Footstep Hybrid Power Generation

Description

This is an advanced, eco-friendly Hybrid Energy Harvesting Project that generates clean electricity from two renewable sources: Mechanical Footsteps (via Piezoelectric sensors) and Solar Energy. Equipped with an ESP8266 Wi-Fi module, this project features full IoT capabilities, allowing users to monitor live voltage and current generation from anywhere in the world via the Blynk Mobile App. It stores the generated power in a rechargeable battery to safely charge mobile phones and other USB devices, making it a perfect solution for smart cities and green energy research.

🔥 Key Features
* Dual Energy Harvesting: Combines Kinetic (Footstep) energy and Solar energy for maximum efficiency.
* IoT Cloud Integration: Real-time data logging and monitoring on the Blynk App via ESP8266.
* Dual Display System: View live stats on both the physical 16×2 I2C LCD screen and your smartphone.

⚙️ How it Works & System Specifications
1. Mechanical Inputs:  Step on the integrated Piezo plate array to generate AC voltage, which is instantly converted to smooth DC via a custom built-in Bridge Rectifier (Diodes + Capacitor filter).

2. Solar Input: The bundled mini solar panel continuously tops up the system using ambient light.

3. Smart Power Analytics: An onboard INA219 current sensor precisely monitors the incoming power and routes data through the pre-flashed ESP8266 NodeMCU.

4. Power Storage & Delivery: The energy is safely stored in a premium 3.7V 18650 Li-ion battery. A built-in booster module provides a stable 5V USB output to power up smartphones.
