Regional temperature and humidity monitoring via mobile sensor nodes

Due to the latest developments in mobile and ubiquitous computing, it is feasible to deploy environment monitoring sensors using a large number of mobile devices. In this paper, we propose a system to continuously monitor a particular region's temperature and humidity. The “server” is a center point (base station) that collects the data. The sensor nodes deliver the data to the server at a given schedule or on demand. The server is equipped with the data visualization tools for conducting visual analytics on the collected sensor data. The proposed system consists of three modules. The first module consists of the mobile sensor devices to monitor the region's temperature and humidity. General Packet Radio Services (GPRS) and GPS module are integrated in the nodes. Further, for continuous and responsive monitoring, there is a real-time communication with these mobile sensor nodes. The second module consists of the components to collect data from the sensor nodes and record the data in the server database. Finally, the third module provides the data mining and data visualization on the recorded data in server database. The proposed system is implemented and tested on several bus routes in Istanbul, Turkey. The results show that the proposed system could be beneficial in developing precise models for the environment monitoring.
