Provide the highest-resolution air quality metrics to thriving communities through cost-effective sensor networks that leverage statistical methods and machine learning to enable understanding of air quality micro-climates.
Empower all community members with simple and accurate air quality metrics to better understand air quality where we live, learn, work, and play.
The company was founded in 2017 as Tetrad Sensor Network Solutions, LLC. and grew from a National Science Foundation grant to develop a low-cost network of sensors to capture air quality measurements throughout the Salt Lake City valley. Tetrad focused on addressing poor measurement quality and on creating engaging visualizations to make sense of imperfect sensor measurements.
TELLUS fills the gap between low-effective air quality monitoring networks and high-cost EPA-compliant air quality instrumentation. The problem with low-cost networks is they can produce inaccurate, unreliable air quality measurements that are difficult to interpret. They can overestimate or underestimate levels of PM2.5 by up to a factor of three. While EPA-compliant systems produce maps with minimal high-quality measurements, they fail to capture local dynamics and monitoring instruments can cost tens of thousands per device.
By utilizing EPA-compliant air quality monitors, TELLUS is able to create calibration factors and produce highly accurate air quality measurements at a hyperlocal resolution. This method expands the reach of local EPA-compliant monitors and offers engaging visualization that accurately captures air pollution measurements across the entire region of interest in near real-time. The more air quality sensors that are deployed, the more accurate the pollution concentration estimates and the farther the geographical reach.
