Measuring temperature and nitrogen levels in soil is important for agriculture systems but detecting them apart from one another is difficult to do. Huanyu “Larry” Cheng, James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, led researchers in the development of a multi-parameter sensor that can effectively decouple temperature and nitrogen signals so that each can be measured accurately. The results were recently published by Advanced Materials.
