MICROSCOPIC AUTOMATIC POLLUTION MONITOR – EU RESEARCH
February 1st, 2006
BY KEITH NUTHALL
A MINUTE carbon dioxide sensor that 'listens' to air quality and alerts ventilation systems as soon as oxygen levels are too low, is being developed by a Scandinavian research team, which has received support from the European Union (EU).
