Air Quality Monitoring using IOT

Work environments, as well as homes and businesses, often require that people spend a majority of their time indoors. As a result, individual’s long-term health and comfort are largely dependent upon indoor air quality testing. Businesses are increasingly interested in air quality monitoring systems to keep an eye on the conditions that maximize worker productivity and save energy. Indoor environments are characterized by several pollutant sources. As people typically spend more than 90% of their time in indoor environments. Thus, indoor air quality (iAQ) is recognized as an important factor to be controlled for the occupants’ health and comfort. The majority of the monitoring systems presently available is very expensive and only allows collecting random samples. This work describes the system (iAQ), a low-cost indoor air quality monitoring wireless sensor network system, developed using Arduino, and micro sensors, for storage and availability of monitoring data on a web portal in real time. Sensors of environmental parameters (air temperature, humidity, carbon monoxide, carbon dioxide and were used. Other sensors can be added for monitoring specific pollutants. The results reveal that the system can provide an effective indoor air quality assessment to prevent exposure risk. In fact, the indoor air quality may be extremely different compared to what is expected for a quality living environment.
