Redes de sensores inalámbricos para IoT: monitoreo del nivel de batería de un nodo LoraWan.

Abstract

Currently, the expansion of the Internet of Things (IoT) has led the industry to research new communication technologies that can meet their needs. One of the technologies that manages to solve the problem of transmitting data over long distances with low energy consumption is LPWAN technology and its LoRaWAN standard, which presents solutions to this problem using low-cost, low-complexity end devices that can communicate wirelessly over long distances, such as the Wio-E5 board, a battery-powered sensor node. In order to monitor the battery level, a prototype was designed and implemented, consisting of a LoRaWAN node connected to a LoRa gateway, and a final dashboard application executed in Node-RED, allowing for the visualization of the system’s data, thus controlling the battery life within a LoRaWAN network and taking appropriate measures when the battery is low. The prototype yielded satisfactory results, detailing its advantages. This prototype is useful in different applications focused on technology development.
