Our three-step process makes air quality monitoring effortless.
When the system is operational and connected to the internet, the ESP32 microcontroller collects air pollution data using the MQ135 gas sensor. The DHT11 sensor measures ambient temperature and humidity. The collected sensor data is processed and prepared for cloud transmission.
This layer functions as a communication bridge between the ESP32 and the web application. Google Firebase securely stores, processes, and synchronizes the incoming sensor data, enabling real-time cloud-based data management and seamless data transmission.
The web application retrieves live data from Google Firebase and presents real-time metrics, including AQI, temperature, humidity, and other environmental parameters, through an interactive dashboard.
