Thunderstorms seem to come suddenly and often have devastating consequences. Whether for agriculture, home, or outdoor sports activities: only those who are warned in time can take precautions. The Franzis Thunderstorm Warning System helps protect against storm damage.

Simple and Educational
This kit makes it easy for you: the circuit board is largely pre-assembled. Therefore, the setup is child’s play. After just a few steps, your electronic thunderstorm warning system will protect you from unpleasant weather surprises. The device analyzes the electromagnetic signals of a thunderstorm in the frequency range around 500 kHz, allowing it to detect when a storm is brewing. Simple additional experiments illustrate the connections.

Three Warning Levels
Three warning levels indicate how far away the thunderstorm is. By the time the red LED lights up, you should take your final safety measures. The device's low power consumption ensures that you are protected all summer long. Simply place your device by the window and leave it on throughout the summer. With the simulation mode, you can check the device's functionality at any time.

Projects That Really Work
Franzis learning kits are characterized by high quality and ease of implementation, even for beginners. All experiments have been tested for their practical applicability. So you can be sure that everything will work at your home as well.
