Desarrollo de una solución integral para la medición de variables meteorológicas

Abstract

This monograph consists of the research, design, and implementation of the hardware and software of an experimental prototype of an automatic weather station (EMA). In the development of the project, sensors such as a rain gauge and a wind speed and direction sensor are manufactured, long-distance communication technologies are applied, and operating modes are implemented for synchronizing the date and time in real time with the Internet, as well as the appropriate backup of the information to always guarantee the shortest consumption time and durability of the components. The power supply circuit allows the EMA to maintain 1.1 days of autonomy, reduce the cost, and have the freedom to choose various types of components for the solar panel and the battery. The prototype station was located at the IDEAM headquarters in Puente Aranda in Bogotá, Colombia. IDEAM allows comparison with a standard station. The results show interesting reductions in the manufactured sensors in terms of the resolution required by the World Meteorological Organization (WMO). Likewise, in general, all the sensors meet the measurement ranges appropriate for the tests. In general, the precision of the sensors did not comply with the WMO, but they show acceptable results for a prototype, implying that the average relative error is less than 15%.
