Our system is able to detect variables such as temperature, humidity, luminosity and CO2 and record them every minute into a micro SD card. We have attached the system into a closed artificial ecosystem that is monitored 24h per day. This platform can be used as an interdisciplinary tool by high school teachers, mainly in biology, ecology, chemistry, physics, informatics and electronics subjects, turning the classes more pleasant and profitable.
