ABSTRACT
Traditional methods to mitigate landslide disasters often have the shortcomings of high cost or high energy consumption, therefore Early Warning System (EWS) is considered a practical approach in a cost-effective manner. This research proposes an EWS with various sensors and a wireless operating platform for data collection, transmission, and analysis based on Internet of Things (IoT). The EWS setup is supported by an off-grid solar photovoltaic system that can ensure one week of operating without any sunshine. The study presents the design, and development of EWS and conducts a case analysis of typical sandy slopes to confirm the feasibility of the system. Experimental validations prove that the EWS could effectively predict the risk and send warning notifications. Research guarantees the accuracy of the EWS while operating in a low-cost and sustainable manner. Therefore, the newly developed EWS can be put into use in both developed and developing countries.
