LoRaWAN Based Smart Room Monitor

Human population is increasingly getting contained in closed office or residential spaces with minimal natural ventilation. Air pollutants that get generated internally or coming in from outside tends to get trapped inside these closed spaces long enough to pose health hazards. Also with these spaces being artificially controlled using power hungry HVAC equipment leading to heavy load on the public electric infrastructure along with inflated electric bills eating into operating budgets. This paper presents a LoRaWAN based smart room monitoring solution to monitor vital room environmental parameters along with a automatic load control scheme that could potentially save up to 30 percent in energy cost along with proportional reduction in greenhouse gas emissions.
