Chlorophyll fluorescence, the reemission of absorbed light by a plant, can be used as a pre-indicator of various plant phenomena. The main benefit of fluorescence is that it can detect issues before a plant shows physical signs of deterioration and does not require chemical testing. However, traditional methods of detecting it are both expensive and invasive. The Horticulture Fluorescence Sensor (HFS) project aims to develop a non-invasive and cost effective remote fluorescence sensor in the hopes of providing real time feedback to greenhouse systems.
