Logging System for Air Quality Mapping

Abstract: An urgent issue in today’s society is the large emissions of air pollutants and CO2. Aside from being extremely harmful to the environment, these emissions can also be particularly unhealthy for inhabitants of metropolitan areas. To help combat this issue, a system for measuring air quality over larger areas is required. In this project a system for mobile air quality mapping was developed, based on an earlier prototype. The system is able to log CO2 levels over large areas, and communicate the measurements to a server when connected to WiFi. The measurements are thereafter inserted into a database, where measurements of several sensors can be stored and accessed. The final version resulted in a system efficiently mapping and storing measurements in a database. This is done whenever a WiFi connection is available for a sensor tracker module. While connected, the module sends measurements to the server in real-time. When a tracker module initiates a WiFi connection, it also uploads any measurements taken while the module was offline. While the system lacks some aspects of scalability and easy configuration, the developed system is largely automated when configured.
