TriSense Sentinel | Multizone Hazard Detection System – Fire & Motion Alerts in Real-Time

Fire or motion — or both — TriSense Sentinel reacts instantly with lights and sound for real-time hazard alerts.

Welcome to Candade LabWorks
This channel brings hands-on electronics and IoT projects to life — from circuit fundamentals to embedded systems and beyond.

🔧 About This Project
TriSense Sentinel is a responsive hazard detection system that combines flame and motion sensing to deliver multi-zone alerts in real-time. With tiered visual and audio cues, simple modular logic with adjustable alert speeds, and scalable design, this project mirrors how layered safety systems work in secure zones — making it perfect for home safety demos, lab security, or future IoT-enabled monitoring.

🧰 Components Used
- Arduino Uno
- Flame Sensor Module
- IR Motion Sensor
- Red LED (Fire Indicator)
- Yellow LED (Motion Indicator)
- Active Buzzer
- Breadboard & Jumper Wires

⚙️ Pin Connections
- Flame Sensor → A0
- IR Motion Sensor → D2
- Red LED → D8
- Yellow LED → D9
- Buzzer → D10

🎛️ Control Logic
- 🔥 Fire Only → Red LED ON + Mid-speed buzzer
- 🚶 Motion Only → Yellow LED ON + Slow buzzer
(Motion sensor outputs LOW when motion is detected)
- 🔥 + 🚶 Both → HIGH ALERT mode (both LEDs ON + fast buzzer)
- ✅ No Detection → All outputs OFF

💡 Technical Highlights
- Analog threshold detection for flame sensing
- Digital trigger logic for motion events
- Sequential event handling with adjustable delays
- Real-time Serial Monitor feedback for debugging
- Modular structure for future IoT/ML integration

📌 What You'll Learn
- Designing multi-trigger embedded systems (fire + motion)
- Handling analog & digital inputs together
- Tiered alert logic with LEDs and buzzers
- Building scalable safety prototypes for IoT or AI upgrades

🧠 What’s Next
- Wi-Fi/Bluetooth alert integration
- Dynamic flame intensity calibration
- Expansion to 3+ detection zones
- Edge ML model for fire pattern recognition
