In this work, we have developed a novel air quality monitoring system capable of detecting multiple air quality parameters including VOCs, CO2, particulate matter of various sizes, formaldehyde, ambient pressure, humidity, and temperature. In addition it has cellular connectivity for real time data transmission that can be recorded and processed through cloud connectivity as well as being GPS enabled. The system is built around a Particle Electron microcontroller which is capable of collecting signals and also transmitting them wirelessly to the cloud for retrieval at a remote location. The system differs from existing systems in the market in both the ability to take accurate measurements and to have complete portability. The former is enabled by careful consideration of design constraints and the latter by an onboard external battery pack that is included in the system to supply portable rechargeable power. In this thesis we have demonstrated the performance of our system’s various sensors as well as having compared it to the best existing system on the market to show its superior characteristics.
