The digital lightning warning system developed by Sunlight uses MEMS atmospheric electric field sensors to monitor the intensity and polarity changes of the cloud-ground electric field. Complying with IEC62793-2020《Lightning and thunderstorm warning system》, the digital system can detect changes in the surrounding electrostatic field within a radius of 15 km at any time and send warning signals at a level about 5-30 minutes before lightning strikes, allowing users to take precautions in time.

The current meteorological system uses radar and satellites to provide long-term and large-scale lightning forecasts, while there is no means to accurately predict thunderstorms in small areas and in the short term. Since this kind of local thunderstorm causes great harm to various major industries, the Digital Lightning Warning System is a device that can monitor regional thunderstorms in small areas and in the short term, providing timely and accurate local lightning warning and preventing lightning disasters in advance!
