Indoor Air Quality Monitoring Systems in the IoT Environment

A Modular IoT Platform for Real-Time Indoor Air Quality Monitoring

The impact of air quality on health and on life comfort is well established. In many societies, vulnerable elderly and young populations spend most of their time indoors. Therefore, indoor air quality monitoring (IAQM) is of great importance to human health. Engineers and researchers are increasingly focusing their efforts on the design of real-time IAQM systems using wireless sensor networks. ...

Indoor Air Quality Monitoring and Control

Using webcam for indoor air quality monitoring

Nowadays application of webcam becomes more and more popular. Thus webcams are being developed to have better resolution but lower cost. This has motivated us to evaluate the suitability of using webcam for indoor air quality monitoring. This monitoring involved determining the concentration of particulate matter with diameter less than 10 micron (PM10). An algorithm was developed to convert mu...

Indoor air quality monitoring in urban areas using Smart Sensing Technology

Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...

Humidification and perceived indoor air quality in the office environment.

OBJECTIVE To evaluate the effect of humidification on the odour, acceptability, and stuffiness of indoor air. METHODS In a six period cross over trial at the Pasila Office Center, Helsinki, the air of two wings of the building in turn were ventilated with air of 30%-40% humidity. A third wing served as a non-humidified control area. The quality of indoor air was assessed weekly by a panel con...
