  Technologies related to the Internet of Things (IoT) have seen remarkable
growth in recent years. This has facilitated, among many other reasons, that
monitoring systems have spread in many everyday areas, including both industry
and the services and systems of the so-called smart home. These systems can
also be applied in Engineering and in Education for the different existing
engineering degrees; and one of the fields is sustainability. A project related
to sustainability and student practices has been launched at our university. In
this way, several objectives are achieved at the same time, such as the
transfer of knowledge from universities to society, and also the development of
sustainable education, in line with the sustainable development goals. In this
framework, we want to apply the ideas of monitoring through IoT applications,
by means of the measurement of certain environmental factors that occur both in
an urban garden and in a composting process. Only open hardware-based devices
have been used in the project. The proposed model can be applied in other areas
of knowledge, having considered different alternatives and having chosen the
best elements, based on sustainability criteria, for each section of the
project. Specifically, in the system that has been created, the environmental
factors of a small urban garden and also of a composting box can be measured.
Both sections of the project, garden and composting, are located at the
university. The factors to be measured are the following: air temperature, air
humidity, soil moisture, ultraviolet radiation and amount of light (luminosity)
received in the urban garden; and temperature and humidity in the composting
process.
