Electronic System for Monitoring Quality of Air and Atmospheric Conditions with Autonomous Power Supply System

Abstract

Pollution and quality of air represent a very important and popular subject in these days. Level of pollution in towers is high, or it is in continuously increasing and there are a lot of warnings regarding this everywhere. The concept from this paper describes a solution for monitoring in every moment the quality of air and the atmospheric conditions. Another important concept from this paper is the energy saving by using solar energy: a photovoltaic panel can convert the solar radiation into electricity and after that this energy can be stored in batteries(for example Li-Ion battery, as in this application). The battery will be charged by the photovoltaic panel during the day, and the stored energy will be used in the nighttime. The presented project is based on the important concepts from above and consists in two parts, a module for gathering the data from different sensors, processing the data and sending to a second module and also to a database. Based on the values from the sensors, graphs are created automatically for storing the history and the user can monitor anytime the quality of air and atmospheric conditions. In the following paper, there will be presented the block diagrams, implementation and testing for the entire system.
