Dong, Xin (2018) Building an Internet of Things (IoT) platform for remote monitoring of field applications using Sigfox Low-power Wide-area Network (LPWAN). Coursework Masters thesis, University of Southern Queensland. (Unpublished)
Abstract
Brisbane City Council has many field applications at remote locations that are difficult to monitor and maintain. Frequent site visits incur high labour costs and unawareness of the accurate condition of the sites can lead to incomprehensive managing decisions. To address these problems, an IoT system can be developed and installed in the field to achieve remote monitoring of the field applications.
This project aims to design, build and test an IoT platform that can be used to monitor two selected field applications at remote locations. The three IoT applications that have been studied are water level and height monitoring, monitoring volumetric percentage of moisture in the soil of the garden and monitoring soil moisture level in landfill remediation fields. Sigfox is the LPWAN used in these applications which is able to provide a coverage of 3-10km in urban places and 30-50km in rural areas. For each application, components of the IoT system have been selected and connected, software programs have been written for the system and a user interface has been set up on the Internet. There are two parts of the IoT system; one is the controller, which is called the IoT solution, this is the same for all applications, the other is the sensor specific for each application.
On successful completion of the project, an end-to-end IoT application using the Sigfox network has been implemented; and the total cost of the developed IoT solution is around $70, which is 14% of the price of a similar commercial Sigfox IoT product. Two field units to monitor soil moisture in the garden and a landfill remediation field respectively have been constructed and deployed. The next step is to a design and manufacture a PCB with an Arduino-compatible microchip, a Sigfox module, an efficient voltage regular and other modules that together make it a low-power board.
