It detects intracloud approaching storms. The US National Weather Bureau suggests the 30-30 rule when 30 seconds later, the storm is within 10 km. Head immediately for a safe shelter. Stay in the shelter for 30 minutes after the last sound of thunder you hear). The AS3935 detects lightning activity as it approaches from up to 40km away which provides a much longer distance for lightning warning. In addition, the AS3935 distance of the storm activity can be statistically calculated from the measured signals. plication. Personal safety can be set at the most conservative alert, whereas equipment thresholds, and false disturber rejection, enable current consumption to be optimized both indoors as well as outdoors, just by changing the gain setting in a register. Portable devices such as GPS, watches, bike computers and hand-helds can moni- tor the environment to warn of potential lightning strikes. Devices such as weather telecom, smart grid systems, medical equipment and computers can switch to battery backed or generator power when strikes threaten the integrity of the power system.
