Development of a Sensor Module for Monitoring Indoor Environments

We developed a sensor module by using various commercial sensors and a wireless communicating module. The sensor module can be used to monitor an indoor environment via its temperature sensor, humidity sensor, light sensor, odor sensor and atmospheric pressure sensor. We also designed a user interface for a tablet PC. While communicating with the sensor module wirelessly, the data of an indoor environment were collected in real time. Using the environmental data, we calculated the Wet Bulb Globe Temperature (WBGT) and the discomfort index (DI) to determine the threshold values of an indoor environment for preventing heat illness and to obtain information on environmental quality.
