Ardudrop 1.0dispositivo electrónico para el estudio de la humedad del suelo

Resum

In this paper, an electronic device, whose purpose is the acquisition of data through various sensors is presented. The data (soil moisture, air temperature, relative humidity, and rain intensity) allow study the evolution of soil moisture depending of the environmental conditions. This device, named such as ArduDrop, at its 1.0 version here presented, was developed by the use of open-hardware: Arduino, and its programming environment in C language (Arduino v17). The complete firmware is also presented in this paper adequately commented. To develop the device ArduDrop 1.0, commercial sensors have been used, but other two (soil moisture and disdrometer) were developed for this device based on earlier works by other authors. ArduDrop is easily reproducible and improved without significant knowledge of electronics or programming, which together with the low price of components and software, makes it of great interest for both scientific and teaching applications.
