Plant cultivation in greenhouse is influenced by various factors, such as soil quality, water availability, and climatic conditions. Techniques have been developed either to adapt food crops to their environment or to adjust the environment to meet plant needs. In this paper, a fuzzy controller (FC) has been implemented for monitored drip irrigation duration to reduce water using as variables soil moisture degree and air temperature in greenhouse. Soil moisture degree can be detected by an electronic circuit based on a capacitive probe. The FC permits to irrigate at the right time, when the plant needs water and the soil water is insufficient. Sensors and actuators (pump and solenoid) are installed and connected to a PC via a data acquisition card NI PCI 6221. A graphical user interface was developed using LabVIEW to acquire data and monitor drip irrigation station.
