LabPi: A Digital Measuring Station for STEM Education 4.0

Abstract

The acquisition of quantitative measurement data has been a challenge in chemistry education for a long time, as the required measurement devices are often too old, error-prone, complicated to operate, or simply too expensive. This paper presents the LabPi digital measurement station, which addresses this problem and provides a solution for science education, research, and teaching. It is built from inexpensive components, is modularly expandable, provides accurate measurements, and is easy for students and teachers to use. It also exploits the potential of digitization to make teaching−learning processes in the classroom as efficient as possible.

Improvement of High-Throughput Experimentation Using Synthesis Robots by the Implementation of Tailor-Made Sensors

“…Overall, the new setup enables a low-cost system for online photometric analysis and the possibility for high-throughput experimentation by increasing the number of photometers in the synthesis robot and reactors in the UV chamber. This approach can thus be the basis for high-throughput synthesis combined with fast and reliable online characterization, e.g., through the LabPi cloud platform COMPare [ 13 , 14 , 36 ]. Future work will aim to implement more devices to achieve parallelization of the experimentation and utilize other self-produced sensors.…”

“…Consequently, the current study focusses on the implementation of a small, low-cost self-produced sensor into a synthesis robot enabling automated online characterization. Therefore, we used prior developed digital measuring system LabPi [ 13 , 14 ]. This system consists of a single-board computer (Raspberry Pi), a tailor-made adapter board, and various small and individually arrangeable sensor modules (e.g., temperature, pressure, pH value, gas sensor, conductivity, and a photometer).…”

The computer is connected to a touch display that can be utilized to operate the analytical software [ 13 , 14 ]. This system is applicable in, for instance, reaction optimization by in situ measurements of pH value and temperature [ 15 ], air-quality tests by measuring CO 2 concentration [ 16 ], hydrogen detection during photocatalytic water splitting [ 17 ], and general chemistry education [ 13 , 14 , 18 ], for which it was originally developed.…”

ZuKon 2030: An Innovative Learning Environment Focused on Sustainable Development Goals

“…ICTs not only are increasingly relevant in the context of gamification concepts but also are seen as innovative for chemistry education. Here, they can take on different functions and serve as learning tools (e.g., explainer videos, small AR learning environments, , learning companions for learning over longer time scales, e.g., learning platforms such as MOOCs, multitouch learning books, AR learning environments) and as digital media for enriching experimentation as experimentation tools (e.g., through digital measure sensors and data logging , ).…”
