Air Quality Monitoring System Using Arduino
Comprehensive guide to building an air quality monitoring system using Arduino. The system will measure the concentration of various gases such as Ammonia (NH3), sulfur (S), Benzene (C6H6) and CO2, displaying the data in real-time
Air Quality Monitoring is crucial in today's world due to increasing pollution levels and its impact on health. This blog provides a comprehensive guide to building an air quality monitoring system using Arduino. The system will measure the concentration of various gases, temperature, and humidity, displaying the data in real-time.
Objectives
Measure air quality: Using the MQ-135 sensor to detect harmful gases like CO2, ammonia, benzene, and others.
Monitor environmental conditions: Controller process the data and act accordingly to provide alert.
Display data: Using an LCD screen to display the readings in real-time.
Components Needed:
Arduino Uno🛒: The central microcontroller that processes data from the sensors and display on screen.
MQ-135 Gas Sensor: Measure the air quality
LCD Display (20x4)🛒: Displays the sensor readings.
Power Supply: USB cable for Arduino or a battery pack for portability.
Inductor, capcitors, resistors and wire🛒: As needed for sensor connections and signal conditioning.
