Implementación de un prototipo de estación meteorológica portátil.

Abstract

The main objective of the project presented below is to implement a prototype of a portable weather station, to create a piece of autonomous equipment that allows one to easily obtain parameters or weather conditions of an exact location and that is portable. For this, it is important to develop the control algorithm, hardware, and software necessary for its correct operation, as well as to establish the necessary parameters to be able to design the prototype and its execution. In this way, a PCB was designed to achieve adequate communication of the whole electronic system, avoiding possible interferences between the elements used. Additionally, sensors were selected with the required characteristics that are compatible to be implemented in the prototype. An electronic board was designed in which an ATMEGA 328p microcontroller was incorporated since it is managed by ARDUINO software with its respective IDE. With this, voltage and current tests were performed on each sensor to verify its correct operation. All the electronic elements are inside a frame for their protection. Finally, this prototype was used to measure climatic parameters such as wind speed, humidity, temperature, altitude, and atmospheric pressure. In addition, the GPS of the mobile device was used to obtain the exact location of the collected data. This information is sent via Bluetooth to a mobile device, so it was necessary to develop a mobile application to visualize the transmitted data. The user decides when to store the data on an SD card, which allows to visualize the history at any time using the Excel program and thus obtain the behavior tables of the measured climatic parameters.
