Since the immediate detection of the damage to foods due to inadequate control of air condition in container is not an easy task and responsibility for any trouble is usually unclear, the transportation of agricultural products overseas from Japan is known to have problems concerned with traceability and food security. In order to find a solution to this problem, the authors have developed a real-time monitoring system of internal air conditions of container through satellite communication and the Internet using sensor network technologies for long-term marine transport of agricultural products. In this paper, we report on the experiment of marine transportation to Dubai from Tokyo in the period of November to December, 2008. Throughout the experiment, it is validated that the present system is one of the most cost-effective real-time monitoring systems and the system could successfully detect a rapid change of temperature and humidity of the container in transshipment at Singapore Port. However, a series of data communication errors often occurred and it was understood that improvement in establishing stable data communication by Iridium satellite must be one of the important future subjects of this study.
