Intelligent System for Irrigation Control



The measurement of soil moisture is carried out through fixed field sensors with high precision regardless of soil type.



The system uses wireless data transmission, connecting the moisture sensor to the user without the need for field cables.



The system remains in the field, powered by photovoltaic panels that provide clean energy to the device



Through the system it is possible to realize the total automation of the irrigation, using the internet to visualize graphs and tables and to control the moments of activation.
