Abstract [en]

The aim of this thesis has been to investigate if it’s possible to build a system that can be used to automate the process of measuring environmental parameters, and to examine the performance of the system. This thesis describes the development of a mobile activity logger and presents the achieved performance of the system. It consists of three subsystems: The mobile unit, the base station and the NAS (Network Attached Storage). The mobile unit measures environmental parameters such as temperature and acceleration, and connects them to a measured GPS position and time. This data is sent to the base station using LoRa which transmits the data to the NAS using GSM where it is stored on an FTP-server. A client application has been developed for accessing the data and visualizing it on the screen. Amaximum range of 1.84 km during line of sight has been achieved between the mobile unit and the base station, with a theoretical battery life span of roughly 50 days. The system has a measured accuracy of 1-2 m in open areas.
