To receive the data output of the modules, a gateway was designed. The computing module is an intel Edison, including Bluetooth Low energy and WiFi. The gateway, in our study, has wired connections to power supply and an USB-interface. For external gateways, a solar panel may provide energy together with a battery. A mobile cellular module and an SD-card enable the data transfer to the internet (Voigt, Helmerich, & Rückschloss, 2017).
