Currently, the water crisis is visible almost everywhere in the world,
and the need to have water available for consumption is essential, since, in
turn, is the main source for life on Earth, wherein of 100% water found on
earth, it is sweet only 2.5%, and of these 2.5%, 70% is used in agriculture,
23% by industries and 7% for human consumption, therefore, it was thought
in a air dehumidifier which has the purpose of obtaining water by means of
condensation, the dehumidifier uses an aluminum plate around 36cm² and
about 0.5 mm thickness, a Peltier tablet TEC1-12706 a breadboard a UNO
Arduino, wires jumpers, TIP122 transistors and 1KΩ (Ohm) resistors. With
the tests we observed the condensed water in the aluminum and the formation
of water, validating the experiment.
