🌊 Flood Rescue Smart Pod 🚨

A self-contained, sensor-driven emergency shelter designed to save lives during sudden flood disasters. The pod automatically detects danger and acts as a safe, insulated refuge until rescue teams arrive.

---

🔍 Overview

Floods strike unexpectedly. Traditional warning systems help—but rarely offer physical protection. The Flood Rescue Smart Pod bridges that gap.

✅ Key Capabilities

• Detects flood onset using water level, pressure, and rain sensors
• Automatically inflates airbag to float above water
• Seals its door to protect occupants
• Sends alert signals (LED + buzzer)
• Operates on battery backup during power outages

---

🧠 System Architecture

• Sensors: DHT11 (Temperature & Humidity), BMP180 (Pressure), Water Level, MPU6050 (Gyro)

• Controller: Arduino Uno

• Actuators: Diaphragm Pumps, LED Lights, Buzzer

• Power Source: 12V Lead Acid Battery

• Software: Arduino IDE + Fritzing + Fusion 360

• Refer to the circit diagram in image folder

🧪 Working Principle

1. Sensors monitor the environment continuously.
2. Once flood conditions are detected:
   • Buzzer and LED alert is triggered.
   • Pump inflates an airbag, lifting the pod.
   • Door seals automatically to prevent water ingress.
3. Gyroscope tracks stability.
4. Status is logged, and alerts are raised.

• Refer to the circit diagram in image folder
