Air Quality Monitoring System

Real-time monitoring of Temperature, Humidity, and Air Quality

📊 Overview

Our Air Quality Monitoring System (AQMS) provides real-time tracking of environmental conditions.

Equipped with the advanced MQ-135 gas sensor for detecting harmful gases and the dependable DHT22 temperature and humidity sensor, the system collects crucial air quality and weather data every few seconds.

This data is securely transmitted to the Firebase Realtime Database using an internet-connected ESP32 microcontroller, ensuring accurate and timely updates.

The dashboard displays this data in a beautiful and intuitive visualization, providing users with easy-to-read insights on air quality, temperature, and humidity levels.

By continuously monitoring environmental factors, the system aims to improve public health and safety by providing real-time alerts on harmful gases and weather changes.

🌱 What These Sensor Readings Mean

Below are the key sensor readings collected by our Air Quality Monitoring System (AQMS). These values provide real-time insights into the environment around you, helping you stay informed about air quality and weather conditions.

🌡️ Temperature (°C)

The current temperature in degrees Celsius. This helps you understand the warmth or coolness of your environment.

🌡️ Temperature (°F)

The current temperature in degrees Fahrenheit, a common measurement unit for temperature in many countries.

💧 Humidity (%)

The moisture content in the air. Higher humidity can make the air feel warmer, while low humidity causes dryness.

🌿 Air Quality Status

This status tells you how clean or polluted the air is. A good status means safe air, while poor or hazardous status indicates unhealthy air quality.

⚡ MQ-135 Voltage (V)

The voltage output from the MQ-135 sensor. Higher voltage indicates poorer air quality.

📊 MQ-135 RAW ADC

This is the raw data from the sensor's ADC (Analog to Digital Converter), helping estimate the air quality level.

💨 MQ-135 Resistance Rs (Ohms)

The resistance measured by the sensor, which helps determine the gas concentration in the air.

🌫️ Estimated CO2 (PPM)

The estimated concentration of carbon dioxide (CO2) in the air, in parts per million (PPM). High CO2 levels can indicate poor air quality.
