Design of versatile and innovative wireless nodes for smart monitoring applications

The project described in this thesis conceived with the aim to realize a device (SwiRem) to remotely monitor electrical equipment deployed in a medium-large external environment. Thanks to Wireless Sensor Network (WSN) technologies, it was possible to identify a pervasive monitoring infrastructure, with a considerable number of miniaturized and independent nodes, which sends information regarding the monitored system to a central collector. The integrated ad-hoc WSN solution, can remotely monitor the power consumption and switch ON/OFF the power supply of a wide number of electrical devices, deployed in an extensive outdoor area. Moreover, the monitoring system must be separated and independent from the monitored one and needs an alternative network to send data and to receive commands. To face the problems of design, construction and testing, it was necessary to create a team of two people, that carried out the entire work together. The SwiRem system was fully implemented with the Texas Istruments CC1310 transceiver, afterwards the system was upgraded with the Murata LoRaWAN CMWX1ZZABZ transceiver. This monitoring approach will be certainly useful in various applications, reducing the time response to a possible breakdown of the device under control. This system allows to electrically turn off a device, without going to the physical place, for power saving aims or to force a power on reset of the DUT. Furthermore, it can collect important data about power usage. Indeed, the testing process highlighted the correct behaviour of the system and confirmed the achievement of expected results.
