Automatic system for control and management of hydroponic and aeroponic cultivation of plants, for the management of a water-based solution contained in a general tank, comprising: - A pump connected to the general tank; - An analysis chamber connected to the pump; - A sensor module comprising sensing probes (102c', 102c'') configured to be immersed into the analysis chamber, a handling support of the sensing probes (102c', 102c'') and a calibration support containing liquids necessary for the calibration of the sensing probes (102c', 102c''); - An additive module comprising at least one liquid nutritional bottle and at least one liquid pH corrector bottle to add the liquids to the water-based solution; - An injection module comprising at least one injector for each bottle (107a, 107b) able to channel the liquids of said bottles (107a, 107b) and send them to the analysis chamber; - An electronic control board configured to: receive from the sensing probes (102c', 102c'') the data of the analysis of the solution sent from the general tank to the analysis chamber by means of the pump; driving the addition of the liquids from the bottles (107a, 107b); enabling the injectors to send a predetermined amount of additive liquids in the analysis chamber; and adjusting the operation of further external devices; and - A user interface configured to wireless communicate with the electronic control board; characterized in that the sensor module comprises a conveyor plane displaceable horizontally by a motor to accurately position the sensing probes (102c', 102c'') and two linear actuators (102d', 102d'') provided with rack and managed, in turn, by two corresponding servo-motors (102e, 102f) configured to immerse and independently remove the sensing probes (102c', 102c''), moving them on two axes. - A pump connected to the general tank; - An analysis chamber connected to the pump; - A sensor module comprising sensing probes (102c', 102c'') configured to be immersed into the analysis chamber, a handling support of the sensing probes (102c', 102c'') and a calibration support containing liquids necessary for the calibration of the sensing probes (102c', 102c''); - An additive module comprising at least one liquid nutritional bottle and at least one liquid pH corrector bottle to add the liquids to the water-based solution; - An injection module comprising at least one injector for each bottle (107a, 107b) able to channel the liquids of said bottles (107a, 107b) and send them to the analysis chamber; - An electronic control board configured to: receive from the sensing probes (102c', 102c'') the data of the analysis of the solution sent from the general tank to the analysis chamber by means of the pump; driving the addition of the liquids from the bottles (107a, 107b); enabling the injectors to send a predetermined amount of additive liquids in the analysis chamber; and adjusting the operation of further external devices; and - A user interface configured to wireless communicate with the electronic control board; characterized in that the sensor module comprises a conveyor plane displaceable horizontally by a motor to accurately position the sensing probes (102c', 102c'') and two linear actuators (102d', 102d'') provided with rack and managed, in turn, by two corresponding servo-motors (102e, 102f) configured to immerse and independently remove the sensing probes (102c', 102c''), moving them on two axes.
