Abstract

Despite the advances in low cost open hardware and open software IoT (Internet of Things) enabled devices, their application in regional scale environmental monitoring has not been explored until the launch of 4ONSE (4 times Open and Non-conventional technology for Sensing the Environment) project, which is an ongoing research project between University of Moratuwa, Sri Lanka and University of Applied Sciences and Arts of Southern Switzerland (SUPSI). The project has paved the path for deploying low cost, open technologies based, non-conventional environmental monitoring systems in Deduru Oya river basin area of Sri Lanka. This research presents the selection process of appropriate sensors suitable for tropical climatic condition of Sri Lanka, issues encountered and remedies taken during the design and deployment phases.
