An IoT-Based System Architecture for Environmental Monitoring

Internet of Things (IoT) has grown in popularity in all spheres of life. Environmental issues in the modern era present a major concern for researchers, scientists and government. In combating the environmental issues, monitoring, identifying and quantifying different contaminating parameters in the environment are necessary, and for this purpose, IoT technology can be extremely useful. In this paper, we propose an IoT-based environmental monitoring system that operates on a four-layer architecture wherein environmental data are captured by a sensor network, aggregated and then communicated to a web server via a cloud service. Then, these data are analyzed by various analytical IoT specific tools and then delivered to the applications for further processing. This system can be cost effective and easy to deploy considering that the underlying architecture is simpler than other existing similar systems.
