Murata Manufacturing Co., Ltd. will carry out a verification test of a system to reduce the risk of COVID-19 infection at shopping streets through visualization of the concentration of carbon dioxide in the air at the Tenjinbashi 3-chome Shopping Street (Kita-ku, Osaka City) and the Namba Ebisubashisuji Shopping Street (Chuo-ku, Osaka City) in Osaka Prefecture.

Adequate ventilation is an important measure for preventing the spread of COVID-19, and one of the indicators of adequate ventilation is the concentration of carbon dioxide in the air. However, since carbon dioxide concentrations vary greatly depending on the environment, it is not easy to measure the correct carbon dioxide concentration. Moreover, even if the correct carbon dioxide concentration can be measured, the lack of clear safety standards is a problem.

Murata will install devices at multiple points along the shopping streets’ arcades to monitor carbon dioxide concentrations using AIRSual, a spatial visualization solution that visualizes and analyzes carbon dioxide concentrations in real time. Since this service does not require setting according to the environment, the correct carbon dioxide concentration can be easily measured. Also, since Murata uses AI and advanced algorithms to analyze whether the carbon dioxide concentration is trending upward or downward, ventilation can be conducted based on quantitative measurements.

By providing this highly reliable service, Murata seeks to contribute to the creation of shopping streets where people can shop with peace of mind, which is what Osaka Prefecture aims to achieve.
