This paper presents the experimental results of an innovative atmospheric humidity collection system for irrigating crops. A humidity and temperature transducer located outside reads the temperature and relative humidity of the atmospheric air. Another transducer located on the indoor unit reads the temperature and humidity of the air leaving the humidification chamber. The controller monitors the temperatures and humidities transmitted by the transducers and when the optimal conditions are met for water to condense on the surface of the external collector, it commands the heating and humidification of the air to start. The system operates until the conditions for humidity condensation are no longer satisfied. The meteorological parameters provided by the local weather station related to the conditions under which water condenses was obtained and led to the adjustment of the automatic algorithm. During the experiments, the following parameters were determined: the flow rate of air pushed by the in-line duct fan, the temperature and humidity of the air jets at the exit from the hot air duct and the volume of water obtained.
