Abstract
Currently, the water crisis is not only visible in Brazil but almost everywhere and it arises where water scarcity becomes a global challenge or environmental concerns about the shortage of drinking water. The need to have water available for consumption is critical, since, in turn, it is the main source for life on Earth. Despite all of Earth’s water found, only 2.5% of it is freshwater. From this smallest part, 70% of it is used in agriculture, 23% by industries and 7% for human consumption. This paper presents an embedded system prototype for air dehumidifying which has the main purpose of obtaining water (by means of condensation). Others benefits include low cost, low size, portability and an Internet of Things application approach. The dehumidifier uses an aluminum plate around 36 cm2 and about 0.5 mm thickness, a thermoelectric Peltier tablet, a breadboard UNO R3 arduino, wires jumper, transistors TIP122 and 1 KΩ (Ohm) resistors. Within the initial results, we verified the condensed water in the aluminum and the formation of water repeatedly and controlled.
