The acquisition of measurement data is a central aspect of scientific and experimental investigations. In research and industry, almost exclusively quantitative studies are carried out. Even in our everyday lives, smartphones and smartwatches measure parameters ranging from battery voltage to our heartbeat. However, for a variety of reasons, quantitative investigations can hardly be carried out experimentally in all subject areas at school and in student laboratories. There is often simply a lack of financial resources to purchase and maintain the necessary equipment (in sufficient numbers). In addition, many of the devices available are often designed for professional use in laboratory analysis and research, which makes it difficult for teachers and students to operate them.

The LabPi project addresses this challenge. The basic aim is to develop a digital measuring station that offers new experimental possibilities for use in schools, student laboratories and universities without the need for any prior programming work. Instead of individual solutions for each measured variable, an open and adaptable measuring station is being developed to which various sensors can be connected as required. By combining inexpensive single-board computers with precise miniature sensors and free software, a wide range of measurement data can be collected, analysed and compared with the associated internet platform in real time. The low cost per device also makes it possible to purchase class sets; in conjunction with innovative teaching and learning concepts of STEM Education 4.0, this opens up new possibilities and examination formats for schools, student labs and university teaching.
