Sensor data processing based on the data log system using the portable IoT device and RT-Middleware

In this paper, a portable IoT (Internet of Things) device developed based on a single-board-computer Raspberry Pi and the extend-sensor board is presented and the positional information system is presented with the data log system based on the portable IoT device and RT-Middleware. First, the potable IoT device developed based on a single board computer and various sensors for data acquisition is explained. Then, Hadoop based database system for the obtained data is presented with RT-Middleware. Next, RTCs for the data log system are explained and the positional information system for visualizing the obtained GPS data on the Google map is proposed based on the data log system and RT-Middleware, where the GPS data is filtered based on its validity. Finally, some concluding remarks are pointed out.
