The Integrated Air Quality and Hazardous Gas Detection System uses Internet of Things (IoT) technology to monitor air quality, temperature, humidity, and hazardous gases like CO₂ and NO₂ in real-time.

ESP8266 firmware that reads gas sensor data and sends it to the server for the Gas Leak Detector project.

Backend that receives and processes sensor data for the Gas Leak Detector project.

An IoT system that alerts you when gas leaks — built with ESP8266, a serverless API, Supabase, and an Android app.
