Learning Equality is committed to enabling every person in the world to realize their right to a quality education, by supporting the creation, adaptation and distribution of open educational resources, and creating supportive tools for innovative pedagogy. In the future, the Kolibri system can be applied to various open area sampling challenge such as fires, lagoons, flares, and landfills.The Foundation for Learning Equality, a 501(c)(3) non-profit organization (hereinafter referred to as “Learning Equality” or “Us”), is the provider of Kolibri (the “Software”). The emission factors of VOCs derived using the Kolibri are comparable with existing literature values. Our results showed that the time series of CO and CO2 concentration and the PM2.5 measured by the Kolibri agreed well with those from the CEMs and the Flyer. The Kolibri was compared against continuous emission monitors (CEMs) and another sampling instrument (the “Flyer”) that had been used in over ten open area pollutant sampling events. Selection of the sensors was based on laboratory testing for accuracy, response delay, cross-sensitivity, and precision. The Kolibri is controlled by an Arduino-based motherboard which can record and transfer data in real time through an Xbee radio module. The sensor system, termed “Kolibri”, consists of multiple low-cost air quality sensors measuring CO2, CO, samplers for particulate matter with diameter of 2.5 µm or less (PM2.5), and volatile organic compounds (VOCs). A new sensor system for mobile and aerial emission sampling was developed for open area pollutant sources, such as prescribed forest burns.
