Greenhouses crop monitoring

UPM Uruguay


Agriculturists want to know as soon as possible the conditions in which their crops are found; Recommendations and alarms of when it is necessary to water, reduce the inappropriate use of resources and improve their performance.

Our solutions allow an evaluation of the environmental conditions for the development of pathogens, based on data measured directly in the field, in order to intervene only when it is really necessary.

The combination of temperature, ambient humidity, leaf humidity and accumulated rainfall data allow those responsible for crop management to detect the most favorable situations for the creation and development of diseases.

The possibility of directly acquiring the data from the sensors installed in the crops offers very reliable results compared to the data obtained through reports from internet providers or other means, since these may have been obtained several kilometers from the crops.


We deployed the following sensor network in UPM’s Santa Ana greenhouse:

• Ambient temperature and humidity: Used to check different micro-climatic conditions in the prevention of diseases.
• Soil moisture and temperature: Moisture sensors, placed in the soil at two different depths, allow evaluating the percentage of water at the surface and at the root level. They are widely used in optimizing irrigation and saving water.
• Leaf temperature: These sensors are useful when observing the passage of water on the surface. In turn, it allows the study of temperature differences in plants. The sensor basically tries to establish thermal equilibrium in close proximity to the space around the leaves.
• Leaf humidity: Double-sided sensors to analyze the humidity on the upper and lower face of the leaf, widely used to prevent fungi.
• Dendrometers: With the micro-variations of the stem diameter, the water stress of the plant and environmental influences can be estimated.
• Meteorological stations: They allow investigating the effects of speed, wind direction, relative humidity and atmospheric pressure on the crop.
• Pyranometers: They allow to measure very precisely the incident solar radiation on plants.

All data is sent in real time to the system and is stored in a database and made available to UPM through a web interface with custom-developed screens.
