Engineers and researchers are increasingly focusing their efforts on the design of real-time OAQM systems using wireless sensor networks. This paper presents an OAQM system enabling measurement of CO2, CO, Cl2, ambient temperature, and relative humidity. In our system, remote users usually employ a local gateway to connect wireless sensor nodes to the external world. In this work, the gateway processes the collected air quality data and transmits the useful data to end-users through a web-server. The nodes are self sustainable as they are equipped with a solar panel and a rechargeable Lithim-ion 2W 3.7V battery. © 2020 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Air PollutionEnergy Harvestinghealth monitoringInternet of ThingsOutdoor air quality monitoringWireless sensor networkAir qualityEnergy efficiencyGateways (computer networks)Mobile computingSensor nodesAir quality dataEnergy efficientGateway processHuman healthOutdoor air qualitiesRemote usersSelf-sustainableWireless sensor nodeReal time systemsConference PaperCopyright : © 2020 IEEE.
