Reefer Container Monitoring System

As the main logistics carrier of international transportation, the container is the main carrier of import and export goods. The role of containers in modern logistics systems has become increasingly prominent. The reefer container maintains temperature and humidity values within a specified range, which can ensure a safe transportation of food and medicines. Therefore, continuous monitoring and transmission of temperature and humidity in the reefer container is of great significance for ensuring the safety of transported products. In this paper, the WSN-IoT (Internet of Thing based on Wireless Sensor Network ） monitoring system for reefer containers is presented. The system hardware and software and the experimental results are discussed.
