air quality analysis using esp32 with blynk app

Описание: Air Quality Monitoring System using ESP32 with Blynk app helps track harmful gases in real time. The setup includes MQ3, MQ5, and MQ135 gas sensors connected to the ESP32. MQ3 detects alcohol vapors, MQ5 senses LPG and natural gas leaks, and MQ135 measures air pollutants like CO₂, ammonia, and smoke. The ESP32 reads all sensor values and sends the data to the Blynk IoT dashboard using Wi-Fi. Users can see live air quality readings, set threshold alerts, and receive notifications on their mobile phone. This system helps monitor indoor safety, detect gas leaks early, and maintain a healthy environment.
