Nowadays embedded solutions based on platform ARM are finding their place on the market. The ARM platform is very popular in the area of mobile devices such as the smart phones, personal players of audio and video, GPS systems etc. This paper describes usage of the IGEPv2 DM3730 device with software for the collecting and processing of physical data. The operating system chosen was the Ubuntu distribution of GNU/Linux operating system, which was adapted for use with the ARM platform. Data source for the proposed measurement system is represented by a sensor network connected to the device through the I2C interface. The data is stored in local databases on the memory card of the device. This paper includes the comparison of the database systems for the proposed application. Connectivity of the device is ensured through wired or wireless connection to a computer network. Application logic of the whole measuring system is installed directly on the development board. For users, the application is accessible through a web browser. Solution shows the use of open source software in the area, which in recent times has been the dominant of proprietary business solutions.
