Abstract
This paper presents a study of long range (LoRa) communication for monitoring of a ship electrical system. Three categories of electrical system include generator, power distribution, and navigation are monitored. A low power communication technology of LoRa is used to transmit electrical variables such as current, voltage, and power are logged and sent to the server. Experiments using LoRa SX1278 and Arduino have been inducted to validate the performance of the communication. Three spreading factors 12, 7, 6 have been tested. From experiments results, the performance of the communication has been analyzed, if has been found that 97% successful data transmission was achieved with maximum distance. Furthermore, small baudrate communication was more suitable for the application.
