We measured carbon dioxide concentrations in a learning environment. Observations took place 24 days from Oct. 22, to Dec. 10, 2009. Through these observations, we obtained that there is a correlation between the number of students in the classroom and carbon dioxide concentrations. Amount of ventilation and air exchange rate change depending on the day of the week. These difference are effected by date, time, classroom. Measurement value exceeded 1,500ppm in some cases. We indicate carbon dioxide concentration measurement results using portable sensor help improving the learning environment. In Live E! project, we are developing weather monitoring units that are equipped with connectivity to the internet at a lower cost. Using this Internet-based framework, we will be able to collect the measurement results in several places and make the learning environment improve based on the detailed analysis.
