Design and Realization of Interconnection of Multifunctional Weighing Device with Sigfox Data Network

With the increasing expansion of IoT networks, people are trying to connect more and more devices to data networks. Nowadays, such devices are made possible by platforms such as Arduino and Espressif. In recent years, one of the areas of interest for IoT has been the development and maintenance of beekeeping. Although there are various commercial solutions for multifunctional hive scales (BeeSpy or Alya), they are quite expensive. In this paper, we present a hardware and software solution to this problem. From a hardware point of view, our goal was to design such a device that would be competitive, capture various data using ambient sensors, and communicate over the new SigFox data network that was introduced in Slovakia in 2018. From a software point of view, we aimed to design and implement an application for smartphones. With this application, it is possible to fully visualize all acquired sensor data. The communication between the multifunction weighing device and the user's smartphone is ensured via SMS messages.
