Abstract
The world today faces a global problem that has been talked about for several years. It is about climate change, an issue of great importance because it affects society, the ecosystem and because not the economy of a country. In this context, Peru is no exception, currently the country is facing difficult and different problems as a consequence of global warming, the change in seasonal periods that are increasingly longer has generated periods of drought, where the soil is arid generating food shortages, causing rationing measures and the non-existence of water, these conditions become the greatest affectation of the towns far from the city, with little infrastructure. According to the World Health Organization, water scarcity affects 4 out of 10 people on the entire planet, thousands die each year from diseases caused by the consumption of non-potable water, given that 18% of the population does not have access to a sanitation network. According to the United Nations, populations that are below 1,700 m3 of water/inhabitant/year are experiencing a situation of water scarcity. In Peru, between 7 and 8 million people still do not have drinking water. Being Huacho the most vulnerable city, groundwater constitutes its main source of water, the extraction is done mainly through tube wells, making it necessary to search for new alternative surface sources. Peltier cells from the condensation of air humidity in the city of Huacho, Peru. In this sense, the methodology consisted of designing and building equipment at the laboratory level to obtain water from the environment with the support of a program developed in Arduino Mega, which is a microcontroller board based on the ATmega1280. This prototype used in electronic circuits under the thermos-electric concept, worked at 3 amperes of current, with an average ambient temperature of 16.32 °C, average relative humidity of 81.97 % and average dew point of 13.22 °C, meteorological characteristics that the city of Huacho for the month of October 2021. It is concluded that through the Peltier cells it was possible to obtain a total volume of monthly water 7148.90 mL, with humidity and temperature being the fundamental parameters to control; in such a way that this system is an alternative in obtaining water resources so scarce and essential for life, a method of relatively low cost to take advantage of water vapor from the environment.
