What is the impact of a classroom environmental factors on the students performance?
project description
The Euregional Sustainability Center (ESC) is a cooperation initiative between Germany and the Netherlands aiming at promoting sustainability in the bordering region. One of the projects we developed investigated the impact of the air quality in a classroom on the pupils' performance.
To collect the necessary data, I developed a DIY sensing box that measured the temperature, CO2 level, humidity, luminosity, and noise level. This box was then offered to schools as a STEM workshop, to be assembled by the children. The workshop included activities such as laser-cutting the box, soldering and wiring electronic components, and programming the board.

process
With the outlines and requirements of the project defined, the next step was to research the possible components, comparing the prices and performance, and other available open-source similar projects that could be used as a reference. The component options were tested, and the code was developed in parallel, increasing the complexity in each iteration, until all functionalities were implemented.
As the sensor device was intended to be produced and assembled by school pupils and mounted on classrooms, the outer box was designed to be laser cut, easy to assemble and to occupy as little space as possible. After many rounds of prototypes and evaluations, the product was ready for the first workshops.
With the input of each workshop, the design of the box was continuously improved to provide a smooth assembly experience and a functional and efficient measuring product.
results
The sensor boxes were successfully assembled by the school pupils and implemented in seven different schools, collecting environmental data from four classrooms per school. It not only measured temperature, CO2 level, humidity, luminosity, and noise level, but also contained a display and buttons with which the students could input their current mood.
The data was periodically sent to the cloud via WiFi, which caused difficulties in the collection, due to unstable signals at some schools. Nevertheless, the device was very well received by the teachers and pupils, increasing their awareness of the classroom conditions and providing them the educational experience of building a sensing device.
