Description
This project is an IoT Air Quality Monitoring System using STM32. The MQ-135 sensor detects air quality and sends analog data to the STM32 board. The STM32 processes this data and communicates with the ESP-01 WiFi module via serial pins. The ESP-01 then uploads real-time air quality data to the Blynk app for remote monitoring. An LCD display shows live PPM values, and when the air quality crosses a set threshold, a buzzer and LED alert is triggered for safety.
