The recent development of electronics and sensors has brought a significant reduction in costs and size of sensor hubs. As a result, there is an increasing number of devices with built-in sensors, which aim to better monitor the operation of devices, facilitate processes and services, etc. With this, the amount of data that needs to be stored, processed and displayed also increased. To show large amounts of data in a human-friendly way and within the correct context - displaying the right data to right people at the right time - the technology of augmented reality is being implemented. The diploma thesis establishes the application for monitoring the data of the sensor network with the help of the augmented reality.
