Monitoring of volatile organic compounds (VOCs) is of increasing importance in many application fields such as environmental monitoring, indoor air quality, industrial safety, fire detection, and health applications. The challenges in all of these applications are the wide variety and low concentrations of target molecules combined with the complex matrix containing many inorganic and organic i...

Carbon dioxide concentration, temperature and relative humidity in an indoor environment are some of the main indicators air quality (IAQ). In addition, these parameters directly related to airborne transmission diseases. this context, ventilation regulation is essential balance safety via renewal, with comfort energy efficiency. research, educational space Faculty Engineering considered as a c...

Adults spend 80% of their time indoors every day, so the quality indoor air is closely related to people's health and life.In this project, an environment monitoring system designed for quality. Data interaction between carried out by means wireless transmission, as monitor PM2.5 concentration, temperature humidity in real through mobile phones.Realization function: For collection various param...

−A new faulty sensor monitoring method based on an adaptive neuro-fuzzy inference system (ANFIS) is proposed to improve the monitoring performance of indoor air quality (IAQ) in subway stations. To enhance network performance, a data preprocessing step for detecting outliers and treating missing data is implemented before building the monitoring models. A squared prediction error (SPE) monitori...

Introduction: Hospitals, as one of the important elements in the health system, play an important role in patient’s health. Fungi are one of the effective parameters on indoor air quality. This study aimed to compare of fungal contamination of two hospitals in Shiraz City. Materials and Methods: Sampling was conducted based on NIOSH 0800 standard (1.5 meters above the ground level with one sta...
