Design of a Water Collector for High Andean Areas using Peltier Cells and Solar Panels

The search for efficient alternatives for water generation in arid areas or areas where it does not rain regularly has affected agriculture to a great extent due to this scarcity of water resources. Despite being a growing problem and affected even more by climate change, the search for alternative solutions to generate water in these arid areas has affected agriculture to a great extent due to the scarcity of water resources. The search for alternative solutions to generate water in these agricultural areas ranges from the use of rainwater to the use of the atmosphere to obtain water using the thermoelectric effect. This article focuses on the latter section, the device was designed using Peltier cells, powered by a solar panel through a PID control using Ziegler-Nichols tuning and a MPPT regulator circuit, all the circuitry was placed in a 3D printed housing. The water production obtained from the designed circuit was approximately 0.8 - 1.1 mL/h. The device responded correctly to the implemented PID control, this obtained water can be used for irrigation of small nurseries and even increase the water production by placing in parallel more Peltier cells.
