The Internet of Things is the interconnection of uniquely identifiable embedded systems and sensors within the existing Internet infrastructure. The obvious implication of the IoT is that everyday objects can become better. This technology can be widely used both in the industry and in the everyday life. Because of the large number of sensors placed in objects, a data collection system is needed which forward data from different sensors to the user in one way. The problem is that there is no standard and also cheap solution which provide robust data forwarding above TCP/IP protocol. A system is necessary that can observe its environment autonomously and can forward data in the right format with the right protocol to persons authorized to access the information. Furthermore, it needs to be reliable, cheap and low power, too. I chose the corresponding hardware and software elements to implement a prototype in GE Hungary Kft. The primery concern was make a software which meets the requirements of mass production. Therefore, I placed great emphasis on learn about the technologies involved in this task. After the presentation of the testing phase, I am going to give an example to a possible use with an Android application.
