Title:
Smart PPE Compliance Monitoring and Reporting System for Underground Coal Mines | SIH Project 2025

Description:
In coal mining, safety is not just a rule — it’s a lifeline. Our project, Smart PPE Compliance Monitoring and Reporting System for Underground Coal Mines, ensures that every miner enters and works underground only when fully equipped with all essential Personal Protective Equipment (PPE).

This innovative system combines IoT, AI, and LoRa mesh communication to create a complete underground safety network that monitors PPE compliance, worker health, and environmental conditions in real time.

🛠 Key Features:
✅ Smart PPE Suit with:

Capacitive touch & reed sensors for helmet and vest verification

Strain gauge in shoes for wear detection

Heart rate sensor for health monitoring

MQ-2 gas sensor for gas leak detection

DHT22 sensor for humidity & temperature monitoring


✅ ESP32 with OLED Display:

Displays PPE status and generates a unique QR code once all gear is worn correctly

QR code acts as a digital safety pass for attendance and entry


✅ AI-Based Computer Vision at Gate:

Face recognition and PPE detection for dual-layer verification


✅ LoRa Mesh Communication:

Ensures reliable underground connectivity

Sends alerts if any PPE is removed or unsafe conditions arise


✅ Web & Mobile Dashboards:

Real-time data logging

Compliance reports and predictive safety analytics


Our system promotes automation, accountability, and real-time safety, ensuring that every miner is protected — every minute, every day.
