| Sumario: |
In Panama, the average relative humidity is 84.5%, therefore, there is concern because high relative humidity can bring respiratory problems due to bacteria and fungi. Therefore, it is imperative to lower its level in closed spaces. The relative humidity and temperature of sheets based on natural fibers (coconut tow), rice starch, coarse salt and silica gel were analyzed, using the DHT22 temperature and relative humidity sensor, still with an Arduino Uno board, with the main objective of prototyping, evaluating, analyzing and verifying if the mixture of these compounds absorbs relative humidity present in an enclosure. The results obtained due to the four experiments carried out showed that the sheets based on natural fibers do absorb relative humidity. It was also obtained that the heat transfer ratio of the sheets, the temperature variation, the area normal to the direction of heat transfer and the thermal conductivity of the material is inversely proportional to the relative humidity, while the thickness is directly proportional to it. The results of this research show that the sheets created are a type of material that tends to absorb a certain amount of relative humidity found in the surrounding environment but having an absorption limit. The use of these sheets based on natural fibers to absorb relative humidity must be studied in greater depth, for their possible uses on a commercial scale. |
