From 1st June 2021, the University of Electro-Communications (UEC) and Chofu City plan to jointly carry out a demonstration experiment to visualize the carbon dioxide concentration in Chofu City Hall and maintain good ventilation as part of an industry-academia-government collaboration.

The demonstration will utilize high-precision compact carbon dioxide sensor developed by the Tanaka-Ishigaki Laboratory (Department of Informatics) and Yokogawa Laboratory (Info-Powered Energy System Research Center) at UEC.

The sensors will be installed on the 1st to 3rd floors of Chofu City Hall, where many residents visit. The sensors will measure the surrounding carbon dioxide concentration and "visualize" the recorded values by displaying the color and numerical value of the sensors. If the measured value exceeds the standard value of 1,000 ppm, Chofu City staff will carry out ventilation in each of the surrounding places.

Furthermore, if the measured value exceeds the standard value, an e-mail alert will be automatically sent from UEC that is collecting data via the wireless networks to the section in charge of Chofu City, and the person in charge will implement procedures for proper ventilation.
