IoT Safety Monitoring System
Real-time Monitoring. Smarter Safety.
An ESP-based safety system tracking hazardous gas, temperature, humidity and fire in real time, with instant multi-channel alerts.
Project overview
A smart safety helmet concept built for underground miners. Multiple sensors feed continuous readings for hazardous gas levels, temperature, humidity and flame detection into Blynk Cloud, where a web dashboard lets supervisors watch zones live and a mobile dashboard puts the same data in a hand. When any reading crosses a safety threshold the system fires alerts through Blynk and email immediately.
What it does
Multi-Parameter Sensing
MQ-2 gas, DHT22 temperature and humidity, and a dedicated flame sensor for fire detection.
Instant Notifications
Threshold breaches trigger alerts across Blynk and email within seconds.
Cloud Integration
ESP8266 pushes readings to Blynk Cloud for real-time monitoring and historical storage.
Mobile & Web Dashboards
Supervisors track live data, history graphs and zone-level alerts from anywhere.
Built for Continuous Duty
Low power, affordable hardware designed to run reliably underground around the clock.
