Abstract

This paper presents an economical UAV system that performs real-time environmental monitoring, including air quality and temperature measurements. The system comprises a Grove multichannel gas sensor and a DHT11 temperature and humidity sensor, which operate under ESP32 microcontroller control, along with a LoRa module for extended-range, low-power data transmission within a 228-gram payload. The system utilizes a local IP-based IoT dashboard to display real-time data, eliminating the need for cellular or cloud connectivity. The system demonstrated its ability to detect spatial and vertical environmental patterns through field tests, which measured gas sensor indices and temperature and humidity profiles in residential, industrial, and academic areas at heights up to 25 meters. The proposed system enables scalable urban air-quality monitoring through commercial UAVs without requiring any infrastructure. The system will receive future improvements through sensor calibration, GPS-based geotagging, and the integration of PM2.5 and O3 sensing modules to enhance measurement accuracy and system functionality.
