Monitoring large number of plants on 24/7 basis in greenhouse or open field


Multi sensing plants in real-time on maximum and effective efficiency of Photosystem II, light intensity, ETR and plant area

CropObserver is an autonomous multisensor that measures parameters that correlate with the maximum efficiency (Fv/Fm), effective efficiency (Fq’/Fm’) of Photosystem II, light intensity and plant area of a large number of plants.
A laser beam is pointed at the plants via a mirror system that is controlled by the built-in computer above the crop. It continuously changes the position of the spot within the crop each 2 seconds yielding thousands of spot measurements within one cycle. It is programmed to measure at each laser spot the efficiency of Photosystem II and light intensity. From these two measurements, the relative ETR (Electron Transport Rate) is calculated. From the number of measured positions containing chlorophyll the plant area is calculated. The light intensity on all the measured spots of the crop is measured every 2 seconds. This yields in real-time a full overview of the light intensity and light sum on the crop per spot. The CropObserver is fully programmable and can be monitored and controlled remotely by a computer or tablet using Wi-Fi or smartphone using 3G/4G.
