What is special about the demonstrator is the range of technologies presented: At its core, the setup is based on a 5-channel LED light, which is controlled via a microcontroller and can grow plants under different light spectra. Photosynthesis simulations can also be carried out. A scientific photosynthesis model is used here, which utilises CO2 concentration and temperature in addition to light intensity. To do this, the light is linked to a CO2, brightness and temperature sensor, which transmits the data wirelessly to a computer via an Internet of Things (IoT) protocol called MQTT.

STEM teachers not only receive a valuable structure for biology lessons, but can also introduce various technological components and show how biology and engineering can interact and what added value this has for the future. A future in which questions about protecting and supporting the environment are becoming increasingly important.

The plant research demonstrator was developed and constructed entirely by Professor Khanh's ALSVV Lab and co-financed by the Department of Electrical Engineering and Information Technology. Other ideas that have already been discussed in the joint exchange between the scientists and teachers include experiments on fermentation and cell respiration – a successful example of science-based, responsible and partner-oriented exchange of ideas and technologies between university and society.

The demonstrator will remain at the Bertold-Brecht-Schule in Darmstadt until 31 August 2025.
