Description

The AS3935 is a programmable Lightning Sensor^™ IC that detects the presence and approach of potentially hazardous lightning activity in the vicinity. It detects intra-cloud activity as well as cloud to ground flashes, often enabling risk to be evaluated for approaching storms. The US National Weather Bureau suggests the 30-30 rule when lightning is imminent (When a flash is seen and the thunder is heard less than 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).
