In this thesis we created a comprehensive system for measuring water level in tank at a remote location and display the data on a mobile device. The tasks cover the preparation of hardware and software for level measurement, as well as the preparation and implementation of the server that holds data in its database. Data is send to server periodically from hardware unit and is available to different clients via mobile web application. The client has access to the current status and the possibility of reviewing the history (trend fluctuations). In the case of predefined thresholds, for example reached the minimum value, the server triggers alerts via e-mail.
