According to the Environmental Protection Agency (EPA), the average American
spends 87% of their life indoors. In another study EPA found that
concentrations of some pollutants are often 2 to 5 times higher than typical
outdoor concentrations”. Indoor air may be polluted with particles
like Lead, Asbestos, Tobacco, Particulate Matter and gases which are toxic
to health in the short and long term. Accurately measuring indoor environmental
conditions and occupancy is a challenge as the current sensing equipment
is costly, bulky and limited in the scope of deployment. Additionally gathering
and sourcing data from such handheld direct read devices is intrusive,
labour intensive and time consuming process. Another perspective on this
is the push towards smart buildings, smart cities and Internet of Things.
Indoor Air and Environment Monitor – IAM is a compact low-cost indoor air quality and environment sensing device enabled with networking infrastructure for remote data sensing and logging. It measures the concentration of harmful gases such as Carbon Monoxide (CO), Carbon Dioxide (CO2) and Nitrogen Dioxide (NO2). Additionally it also measures ambient parameters such as temperature, humidity and ambient illumination. It also facilitates minimum effort device provisioning to connect to the Internet.
