Climate change is increasingly bringing with it extreme weather events such as flooding.

In order to be able to react better to such situations, it is important to observe the weather closely - for example the humidity.

As part of a collaborative project between the Hector Seminar and Mannheim University of Applied Sciences - under the supervision of Prof. Christof Hübner - 18-year-old student Felix Zhang has developed a measuring device that can measure humidity very accurately.

It works according to a simple principle that consists of evaluating the temperature difference between a dry and a humidified temperature sensor.

Felix compared his measuring device with reference sensors and was able to demonstrate a very good match. He designed the housing on the computer and created it using 3D printing.

Felix won 2nd place in the “Physics” category at “Jugend forscht” with his project.

His aim was to develop an accurate but inexpensive device for weather observation - an important step for environmental protection and disaster control.
