Recently, coronavirus has spread worldwide and is becoming a major challenge. Under such circumstances, coronavirus inactivation using ozone has been reported. We have also installed a Sigfox antenna at Hiroshima Institute of Technology and have been developing Internet of Things (IoT) devices through the Internet using the Sigfox network. In this study, an ozone generator and an IoT device, which is an ozone concentration measuring device with a Sigfox communication function, were used to show the ozone concentration on a computer. Additionally, using feedback control, we obtained a CT value of 60, which can inactivate coronavirus from 1/10 to 1/100, after operating for 24 h at an acceptable ozone concentration (less than 0.1 ppm).
