Abstract

The article presents an idea of building a wide-area sensor network for monitoring the environmental state. The network combines different technologies for data acquisition and is heterogenic in that it is suited to use different data transmission technologies. A distinguishing feature, making this network different from its existing counterparts, is its easy expansion by adding new sensor types, as well as its scalability and functional universality.

Summary

INTRODUCTION

The air state monitoring has been gaining on importance recently, in densely populated clusters and in the vicinity of industrial plants [[1]]–[3]. It may include: air pollution by gases and dust, electromagnetic field level in a broad spectrum, contamination of water and soil, noise level, the amount and composition of sewage, the amount and characteristic of accumulated precipitations and various other elements of live nature, according to given requirements. Important is the air state indoors – in offices or production halls as a correlation has been found to exist between the workers’ respiratory comfort and their working effectiveness or production quality. Wroclaw University of Technology is involved in a project aiming at creating a modern, yet inexpensive, and most of all – scalable system for environmental monitoring, capable of adopting sensors of arbitrary physical phenomena and chemical compounds
