Data collector service - practical approach with embedded linux

Nowadays embedded systems are one of the most important application areas in information technology. Embedded systems are often used in life critical situations, where reliability and safety are more important criteria than performance. This paper presents a data collector service that has been developed based on embedded Linux, which operates as a key element in a larger intelligent alarm system. The target of this study was to test out how well a cost-efficient single-board computer could be used to gather sensory data, and how this data can be provided for the client over the public Internet. The paper describes the data collector service currently in use and its functionality and also gives a concrete example of how to utilize a microcontroller with an embedded Linux distribution. The paper presents one solution on how to utilize embedded systems for managing and controlling conditions in buildings and also environmental conditions in a smart and cost-effective way.
