Showcasing Urban Trees for Environmental Education with IoT Technology. SUTEE is an ERASMUS+ Strategic Cooperation Partnership in the field of school education project.
First version of the SUTEE IoT prototype ready to test
On
The first version of the SUTEE IoT prototype was ready to be tested before the 4th Transnational Project Meeting and the Learning Teaching and Training (LTT) workshop for the “SUTEE: Showcasing Urban Trees for Environmental Education with IoT Technology” project, celebrated in Viena (Austria) from May 19 to 23 2025.
The developed system involves 3 main modules created by UNED researchers:
An electronic prototype, based on an Arduino Nano board that reads data from several environmental sensors, such as temperature, humidity, CO2, and pollutants in the air (CH20, TVOC, PM2.5 and PM10). A white 3D printed case was specially created for this prototype with the SUTEE logo. This electronic board required to be powered by a power bank.
2. An Android app that wirelessly connects to the sensor via Bluetooth Low Energy. This app allows users to take samples of temperature, humidity, CO2 and air pollutants in different points of an excursion. The use of the app is very simple. The participant first has to click on connect sensor to connect the mobile app with the sensor. Then start a new excursion by writing its name.
Once the excursion has been created, the participant just need to take samples along its excursion by clicking the button “Get data”.
