An Open Source IoT Framework for Environmental Sensing

With the rapid development of technology and the competitive technology revolution, climate monitoring systems too have gained more advanced in vast functionalities. Thus, a large set of environmental real-time data can be generated from modern smart devices. Also, open weather monitoring systems too have been introduced in various parts in Sri Lanka to observe the weather data and analyze climatic conditions. These monitoring systems primarily measure climate data, rainfall, humidity, temperature and wind speed mainly. However, it has been observed that the climatic parameters deviate more from the original due to various reasons. Currently Sri Lanka does not have a proper well-connected weather observing network that routinely provide data with necessary quality and temporal density. As same as the weather monitoring systems developed by similar developing countries, systems already developed by Sri Lanka too are not real time. And also, they are not dense enough to monitor local conditions that can evolve rapidly. Major reasons for this situation include the limited budget, lack of technical infrastructure and associated expertise, rapid deterioration, lack of skilled maintenance, high-priced non-locally available spare parts etc. This project aims to develop open technologies based non-conventional environmental monitoring systems for deploying low cost, in Deduru Oya river basin area of Sri Lanka.
