Thunderstorms seem to come suddenly and often have devastating consequences - whether for agriculture, the home or outdoor sports activities. Only those who are warned in good time can take precautions. The 'do-it-yourself thunderstorm warning device' provides a remedy. The circuit board included is largely pre-assembled. Assembly is therefore child's play. After just a few simple steps, the electronic thunderstorm warning device protects you from unpleasant weather surprises. The device evaluates the electromagnetic signals of a thunderstorm in the frequency range around 500 kHz and thus recognizes when a thunderstorm is in the air. Three warning levels indicate at what distance the thunderstorm is located. The low power consumption of the device ensures that the thunderstorm alarm works all summer long. The device is not suitable for children under the age of 14.
