We developed a low cost outdoor carbon monoxide analyzer called APOMOS (Air pollution Monitoring System) based on electrochemical sensor managed by microcontroller. In order to validate the APOMOS system, the recorded measurements are compared with measurements taken by a conventional analyzer. Comparison of the measurements resulting from conventiona l analyzer and those resulting from the APOMOS system gives a coefficient of determination of 98.39 %.enAir quality, carbon monoxide, electrochemical sensor, microcontroller, APOMOS.Article
