"My team had the pleasure of working with 2B Technologies in a study to better understand data from our Love My Air sensor network. 2B was able to deploy an AQSync to monitor alongside our sensors in the field, while providing us with real-time access to data. This study proved to be invaluable to the Love My Air program as we work to improve our data quality. Thank you 2B for your expertise and continuing to be a resource for us now and in the future!”
