The goal of this thesis is the design and implementation of an interface able to connect to a LoRa network a set of water meters equipped with a Wireless M-Bus radio module. In the future, thanks to this gateway, it could be possible to acquire the meter's readings from remote, without direct human interaction on each measurement device. This thesis took place in the framework of a collaboration between the SMAT (Società Municipale Acque Torino) and the iXem Laboratory inside the Politecnico di Torino. The water meters in use during the tests were provided by the municipal company, whereas the laboratory and electronic equipment used are iXem's and Politecnico's property.
