The LED’s spectrophotometry in precision agriculture: A brief survey

Precision agriculture is one of the research fields with the greatest development in recent years. Its target is to reduce the waste with the help of seeking methods that allow fruit and vegetables to be grown in a sustainable way by reducing the environmental impact of fertilizers, pesticides, water leaks and so on. To do that, many agricultural companies experiment specific scientific optical techniques as spectroscopy or fluorescence measurements. This permit to get interesting data on the health status of a plant or fruit/vegetable. In spectrophotometry, the use of LEDs has the advantage of using a light source at a certain wavelength which corresponds to the color of the light emitted and this can have various experimental advantages, which allow for rapid diagnostic analysis of the target without carrying out invasive measurements.
