Abstract:
This study focuses on the development and practical implementation of an
environmental monitoring station utilizing the Arduino Pro Mini microcontroller. The
station is designed to measure and record various air quality parameters such as PM2.5,
CO2, VOCs, ozone, temperature, humidity, light intensity, and UV radiation. The system integrates multiple sensors, including the PMS5003 for particulate matter, MH- Z19 for CO2, MP503 and MQ-131 for VOCs and ozone, and DHT22 for temperature and humidity. The Arduino Pro Mini serves as the central microcontroller, processing data from these sensors and transmitting it to a Nextion touchscreen display for real- time monitoring and analysis. The study reviews 17 related research papers to identify current trends, resolved and unresolved issues, and future directions in the field of microcontroller-based environmental monitoring systems. The results highlight the system's capability to provide accurate and real-time air quality data, demonstrating its potential for broader ecological monitoring and public health applications. Future work aims to enhance sensor integration, system scalability, and IoT connectivity for remote monitoring.
