Data on sensor position and emitted pollutants were acquired in a single room space to establish a pollutant database through long-term continuous measurement. To establish this database, five types of flooring database and nine types of indoor air pollutants were used. Positioning data were immediately transmitted to the MEMS sensing instrument via Bluetooth to monitorand IAQ. Also, through cloud connection of Beacon and WEB APPs, data were integrated into the IoT information platform, using various mobile phones and computers. In the future, the information model can be extended to entire-building recognition, and the use of building space can save labor costs and shorten the operation time.
