Abstract:
Air pollution affects life quality and already has measurable impact on the human health and ecosystem change. It is widely accepted that in order invert the continually growing pollution, citizen awareness policies must be adopted and encouraged. Under this concept large data sets are collected using new measuring systems adopting low cost technologies. This tactic led to the need of evaluating low cost sensing systems in order to be able to collect valid measurements and been able to use them and provide as accurate information as possible. Many research teams are working on this topic studying various factors that affect measured quantities like the temperature and humidity are and propose new low-cost monitoring systems, aiming to developing a network over large geographic areas. This work presents a low cost, low energy consumption and high processing power monitoring station. The monitoring station incorporates Alphasense electrochemical sensors of measuring NO2 and O3 as well as NO2-B43F and OX-B431. In order to be able to design proper calibration and correction formulas temperature, humidity and barometric pressure are also measured and in this work the results of the above process are described. Results collected from two monitoring stations that were installed next to official measuring point of the National Observatory of Athens are presented herein for the NO2 and O3 quantities.
