Estação meteorológica automática de baixo custo

Abstract

With the increase in world demand for food production, it is necessary to think of ways to optimize production, making it more profitable, efficient and sustainable. In this context, the use of meteorological stations in the field has become increasingly common, due to their various applications for agriculture such as monitoring soil temperature, obtaining accumulated precipitation, planning operations, etc. However, many times its implementation and maintenance costs become a barrier for its use to be disseminated on a large scale. With that in mind, this work aims to develop an automatic weather station using low-cost sensors easily found on the market and the ESP32 microcontroller with an easy programming language and wide connectivity. For this, it was necessary to design and manufacture all the sensor shelters that make up the station, as well as to develop software in C and PHP to read the sensors and send data to a MySQL server. Data were collected in an experimental field at UFMT- Campus Sinop and later compared with data from a Campbell reference station (also installed at the University) with the aid of graphics obtained through scripts developed in Python.
