Peruvian Navy uses a Supervisory Control and Data Acquisition (SCADA) system to monitor and control its remote meteorological and luminous stations which are out of town and powered by photovoltaic systems. They use cellular gateways with high energy consumption to transmit data to a control center using the services of a mobile service provider. The storage of the obtained information and system management is done in a single location. This paper focuses on the design of an IoT-based solution using LoRaWAN technology and a cloud IoT platform to replace the current system and give mobility, redundancy and efficiency characteristics. The path loss and coverage for the farthest remote station is calculated using the Okumura-Hata propagation model and two radio propagation simulators. A LoRaWAN end-node with meteorological sensors is simulated and a web page is developed to show the information to the users.
