Abstract Nowadays, with the rapid increase in world population, potable water shortage has started to create serious problems. Many factors such as increased water consumption, environmental problems and climate change cause the decrease in potable water resources. In this study, a fully automatic system which produces water from ambient humidity developed to provide solutions especially in areas where access to clean and potable water resources is difficult. Moisture and salt are used for raw material. CaCl2 salt is not very good for moisture absorption, but when compared with other salts, it can provide a great advantage under human health and cost. The machine is also reinforced with electrical equipment and measures the ambient temperature, pressure values and humidity, consumed energy and prints it on the memory card (SD card) in real time. While the system is running, it can be controlled and read over the phone. Experiments have been carried out and the changes in the amount of water produced and the amount of salt consumed depending on the ambient humidity and temperature have been investigated. The amount of energy consumed by the system was also analyzed. It was observed that the amount of water produced was directly proportional to the ambient humidity.
