Realization of instrument for environmental parameters measuring

Abstract

As the effects of global warming are spreading all over the planet, the activities on monitoring the environment are getting on importance and are becoming the focus of many projects, in particular those targeting development of smart cities and smart societies in general. Development of technology is enabling implementation of low-cost environment monitoring systems that can be installed across the cities utilizing the existing city infrastructure (for example attached to lampposts or installed on public transport vehicles) or even carried around by individuals contributing to crowd sourced based monitoring solutions. However, even though the costs are significantly lower than just a few years ago, it is still prohibitive to deploy such systems on a very large scale. This paper presents a possible approach towards significant reduction of the number of measurement points as well as the number of required sensors while still providing reliable estimations of environment parameters across an area. The approach is based on the mathematical statistics methods. It is shown that the proposed solution works well in the areas with stable and slowly-changing weather conditions, i.e. in cases when there are no sudden climate changes.
