Field data transmission system by universal mobile telecommunication network

Abstract

The new field data transmission system using universal mobile telecommunication network, SESAME-II system, was developed and applied to monitor the items which related to global warming in tropical peatlands, Indonesia. The transmission system is mainly composed of the sensor, the data logger, the data communication module and the battery system. The sensors for water depth, distance, moisture tension and length of circumference were combined with SESAME- II, used to measure the groundwater and ground surface levels in peatlands, the water levels in the river and the dam lake, the soil moisture and the growing process of trees in a plantation, in Indonesia. The interval of monitoring was 10 min, and the data were transmitted successfully to the data server in Japan with 3-6 h interval. The data in the server was downloaded in Japan and Indonesia through the domestic internet network and analyzed.
