Abstract	To empower high school and undergraduate students to become citizen scientists, we describe the design, construction, and operation of a multisensor device based on Arduino microcontroller technology to record atmospheric measurements relevant to secondary organic aerosols (SOAs). The handheld "AIRduino" multisensor device was built and deployed by undergraduate and high school students to simultaneously measure the concentrations of ozone (O[subscript 3]), volatile organic compounds (VOCs), temperature, humidity, and aerosol particulate matter with 2.5 and 10 µm diameters (PM[subscript 2.5] and PM[subscript 10]). Paired with a smartphone via Bluetooth, the data are streamed in real-time to an app interface for on-demand SOA profiling, and the results are recorded with on-board storage using a storage device (SD) card. Furthermore, the AIRduino SOA measurements are calibrated with the regional atmospheric data from the CAPABLE site at the NASA Langley Research Center. Subsequently, the regional chemistry composition was monitored for several days with the AIRduino device to correlate gas-phase molecule concentrations to the formation of aerosols. The mobile AIRduino multisensor device is low-cost and readily accessible for students, thus making it an ideal vehicle to obtain crowd-sourced SOA measurements and to foster excitement in science, technology, engineering, and mathematics.
