An Intelligent Wireless Sensing and Control System to Improve Indoor Air Quality: Monitoring, Prediction, and Preaction

Abstract: The aim of this study is to construct an intelligent wireless sensing and control system to address health issues. We combine three technologies including (1) wireless sensing technology to develop an extendable system for monitoring environmental indicators such as temperature, humidity and CO 2 concentration, (2) ARIMA (autoregressive integrated moving average) to predict air quality trends and take action before air quality worsens, and (3) fuzzy theory which is applied to build an energy-saving mechanism f… Show more

“…Recently, several new systems have been developed for monitoring environmental parameters, always with the aim of improving indoor air quality efficiency [8]. Actually, the availability of affordable sensors, processing units, radios, and Wi-Fi communication technologies integrated in a single board is leading to the use of wireless communications and computing for interacting with the physical world in applications such as air quality control [9].…”

“…This study suggests that predicting particulate matter pollution levels in the indoor environment requires a different technique than ARIMA proposed by Yu et al [20] for indoor air quality based on CO2. The unsatisfactory results observed with ARIMA may be due to the uncertainty in the continuity of the PM2.5 levels in the indoor environment.…”

“…Such a system is controlled based on the schedule, e.g., the ventilation is switched on automatically at a certain time, for example, one hour before bedtime, or smoke detectors are triggered in the case of high concentrations of carbon dioxide [5]. Under the optimum air parameters, the system will operate in economy mode.…”

“…Deviations in either direction can lead to negative consequences. In particular, overly dry air reduces the body's resistance to viral diseases, and too much humidity in a room promotes the growth of mold and mildew, and causes a variety of allergic reactions [5].…”
