Detailed information:

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 ­ ashes, 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 ­ ash 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). 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 identi- es and rejects interference signals from common man-made sources such as:
­ fluorescent lighting, microwave oven, switches, etc. Based on scienti- c research, the distance of the storm activity can be statistically calculated from the measured signals. This information allows the user to set warning levels appropriate for their speci- c application. Personal safety can be set at the most conservative alert, whereas equip-ment protection can balance con- dence, signal strength, and battery life. The programmable thresholds, and false disturber rejection, enable current consump-tion to be optimized in all applications. The ­ exible IC allows for con- gurability that allows the part to work both indoors as well as outdoors, just changing the gain setting in a register. Portable devices such as GPS, watches, cell phones, and hand-helds can monitor the
environment to warn of potential lightning strikes. Devices such as weather stations, clocks, and pool equipment can warn of approaching lightning strikes in the area, with a relative con- dence. Devices protecting equipment such as UPS for telecom, medical equipment, televisions, and computers can switch to battery backed or gene-
rator power when strikes threaten the integrity of power supply and quality.
