Keywords:
arduino pro mini, nextion display, air quality, real-timeAbstract
Air quality monitoring is essential for protecting human health and the environment. This
project presents the development of an Smart Air Quality Monitoring System with Nextion Display
that integrates various sensors, including the DHT22, PMS5003, MH-Z19, MP503, and MQ131.
The system incorporates a Nextion Display for real-time data visualization and a solar panel for
sustainable power supply. The Arduino Pro Mini microcontroller board serves as the core
component of the system, facilitating the collection, processing, and transmission of air quality
data. The DHT22 sensor provides accurate readings of temperature and humidity, enabling
comprehensive environmental monitoring. The PMS5003 sensor measures the concentration of
particulate matter, while the MH-Z19, MP503, and MQ131 sensors monitor carbon dioxide, ozone,
and nitrogen dioxide levels, respectively. The collected data is processed by the Arduino Pro Mini
and displayed in real-time on the Nextion Display, allowing users to monitor air quality parameters
effortlessly. The system integrates a solar panel to provide a sustainable power source, ensuring
uninterrupted operation and reducing environmental impact.The results demonstrate the system's
ability to provide accurate and timely measurements of temperature, humidity, particulate matter,
carbon dioxide, ozone, and nitrogen dioxide concentrations.
