A brief description of the project:

In recent times, varieties of agro sensors have been developed in the pursuit of smart precision farming. The communication module of these sensors have antenna above the ground for transferring data from one sensor to another or to a nearby base station. However, growers have complained about above-ground sensors being easily damaged by machinery, stock and pests, and the hassle of moving sensors out of the way of in-field machinery. The solution lies in developing sensors with underground communication capability. This research will model underground sensor communication, develop prototype and test in farms. It will seek to model and optimise signal transmission distance at the lowest possible power consumption. The research will explore the use of different forms of low power wide area network technology (e.g., LoRa, Sigfox, NB-IoT), noise reduction protocols, variable soil moisture- transmission power requirements, soil type relationships on data transmission, and power harvesting opportunities. A prototype will be built and tested in agro farm environment.
