Study of the Waterproof Shelter Colour Influence on the Atmospheric Temperature and Humidity Measurements for an Internet of Things Application

摘要

Atmospheric temperature and humidity are parameters of great interest in precision agriculture or air quality assessment in urban agglomerations. The emergent technology of Internet of Things comes with the possibility of obtaining information from the field using low power consumption devices equipped with sensors and communication circuits. A device for measuring atmospheric temperature and humidity was built and housed in an acrylonitrile butadiene styrene material. Due to the solar irradiance, the body of the enclosure gets warm and could alter the measurements by thermal conductivity and radiant energy. The study investigates the influence on the measurements of these parameters by the colour of the shelter since there are tendencies to cover it with different paints for artistic design reasons. Three different colours were taken into consideration, white, grey and black. Experiments have to be performed simultaneously in order to meet the same input conditions for solar radiation and air humidity.
