Abstract
Air quality significantly impacts health and overall quality of life, making its measurement essential. However, most affordable air quality devices are designed only for use within WiFi range and cannot handle extreme temperatures, limiting their usefulness for people in remote or extreme environments, such as regions with harsh winter climates. This limitation is concerning, as winter often brings worse air quality due to temperature inversions that trap pollutants and increase fuel burning for heating. Inversion is a problem as close to home as Utah Valley, and as far away as Ulaanbaatar, Mongolia. Most low-cost air quality sensors are not built for rural, remote, or mobile locations, leaving these areas underserved by current technology. To address this gap, we developed a durable air quality sensor designed for long-term use in harsh, frontier environments. Our sensor performs reliably in extreme climates, withstanding temperatures as low as -40°C, and ensures dependable data collection and remote storage. Equipped with robust wireless networking, it uses cellular technology for real-time data transmission and features a secondary Long Range (LoRa) radio, enabling coverage in areas without cellular service.
