S.E.A.M. | Skyborne Environmental Alert Mechanism – Multi-Sensor Hazard Detection in Real-Time

✨ This project was built by my teammate Thejas S. and me, and we proudly presented it at Open Day 2025 (Electronics Dept, JSSSTU).

Welcome to Candade LabWorks
This channel showcases hands-on electronics and IoT projects — from basic circuits to embedded systems and beyond.

🔧 About This Project
SEAM Skyborne Environmental Alert Mechanism is a compact multi sensor safety system that detects tilt, distance, temperature, and humidity hazards - all visualized on an OLED display with multi-level LED and buzzer alerts. Inspired by spacecraft hazard monitoring, this project shows how multiple sensor inputs can be fused into a real time alert system.

🧰 Components Used
Arduino Uno
DHT22 Temperature and Humidity Sensor
HC SR04 Ultrasonic Distance Sensor
Tilt Switch Sensor
128x64 OLED Display SSD1306 driver
3 LEDs Red, Green, Blue
Active Buzzer
Breadboard and Jumper Wires

⚙️ Pin Connections
DHT22 - D2
Ultrasonic - Trigger D3, Echo D4
Tilt Switch - D7
Green LED - D9
Blue LED - D10
Red LED - D11
Buzzer - D12
OLED - I2C SDA, SCL

🎛️ Control Logic
⚠️ Tilt detected - Red LED ON + buzzer constant ON
📏 Distance less than 10 cm - Blue LED ON + buzzer beep 200 ms
🌡️ Temperature above 40°C or abnormal humidity - DANGER flagged
✅ Otherwise - Green LED ON (SAFE mode)
OLED updates every 1.5 seconds with live readings and status

💡 Technical Highlights
Multi sensor fusion combining digital and analog inputs
Prioritized alert handling - tilt then distance then temperature and humidity
Real time OLED visualization of sensor values and status
Serial monitor feedback for debugging
Modular structure for scaling alerts and upgrades

📌 What You'll Learn
Integrating multiple sensors into a single embedded system
Designing conditional alert logic with priority levels
Displaying real time data on an OLED screen
Prototyping environmental monitoring and safety systems

🧠 What’s Next
Add EEPROM to log alert history
Smarter OLED dashboards with graphs and logs
Wireless alerts using Wi-Fi or Bluetooth
Adjustable thresholds for custom applications
AI and ML integration for anomaly detection
