Development of a Vehicle-Mounted Environmental Monitoring System for Fresh Food Transportation

Abstract

To meet the growing demand for real-time environmental monitoring in fresh agricultural product distribution, this study proposes a vehicle-mounted monitoring system based on LoRa wireless communication. The system consists of temperature and humidity sensing units and remote receiving modules, enabling low-power and reliable data transmission. The hardware architecture, functional design, and embedded software of both sensing and receiving devices are systematically developed. Performance tests demonstrate that the proposed system can accurately monitor temperature and humidity conditions and provide timely over-limit alerts during transportation. Experimental results confirm that the system operates stably with low energy consumption, making it suitable for intelligent cold-chain logistics and fresh product distribution applications.
