The human eye can only notice certain changes on the plants (shriveled leaves, yellow and brown leaves, spots on the plant ...), but then it may be too late for the plant.

Plant-O-Meter notices changes even before they become visible, analyzes and evaluates how healthy the plant is, ie what is the ability of photosynthesis, whether there is a need for fertilization and irrigation.

The device emits light from carefully selected parts of the spectrum that is reflected by the plant and provides a precise assessment of its condition in just a few seconds.

The data is sent via bluetooth to the smartphone to which the device is connected, through which it is further transmitted to the information system along with the GPS location of the sample.

Also, the device is designed to display measurement results regardless of the time of day and weather conditions.

The director of the BioSens Institute, Vladimir Crnojevic, says that this prototype is an important step forward in agriculture and that cooperation between science and industry must be strong and multifaceted in order to have a comprehensive impact on the economic development and well-being of the entire society.

The device will be easy to use and affordable - its price will be much lower than the competition so that local farmers who want to apply the concept of precision agriculture can be more easily involved in the digitalization process.
