offeringssummarize
The sensor node can automatically, continuously and accurately measure the transmission radiation of the vegetation and calculate the leaf area index of the vegetation by calculating the transmission capacity of the vegetation to different angles of solar radiation. The Leaf Area Index (LAI) meter has the capability of automatic network observation, which is suitable for long-term unattended measurement when deployed in field observation stations.
Application Cases
XST-LAINet series leaf area index meter has been verified in remote sensing applications, and the related results have been published and cited more than a hundred times in papers of famous journals, including Remote Sensing of Environment and Science Bulletin.
