Abstract:

The constant climatological changes that we have observed in recent years force us to understand and better comprehend the variables that are directly or indirectly related to these changes, such as temperature, humidity and concentration of carbon dioxide in the atmosphere. This article presents a platform for meteorological monitoring in a controlled environment with the aim of teaching high school students about the Environment and the Internet of Things (IoT), especially in teaching how to obtain climate data from a given environment. For this, we used active teaching-learning methodologies and maker culture, which is based on the idea that students learn better when they are engaged, reflecting, discussing, collaborating and applying knowledge in real situations. The proposal made it possible to develop a low-cost didactic platform that is, above all, easy to access, handle and configure using a IoT system as a basis, using ESP32 device and humidity, temperature and carbon dioxide sensors. The system architecture consists of the development of a gateway that creates its own wireless network so that the sensors can easily connect, and thus be able to capture the variables collected in each sensor. Results obtained in a team composed of three Technical High School students in Mechatronics and a postgraduate student in Environment showed that the integration of these different levels of education with the Environment and technologies contributes to hands-on learning, with knowledge gain for all students, both in Environmental Education and IoT.
