Lightning sensor IC targets low power, portable applications

Austriamicrosystems has introduced the worldís first lightning sensor IC, the AS3935 Franklin Lightning Sensor with an embedded intelligent algorithm.

Named after American innovator, Benjamin Franklin, the austriamicrosystems low power lightning sensor provides people with advanced warning of approaching electrical storms giving them additional time to take shelter.

The AS3935 Franklin Lightning Sensor utilizes a sensitive RF receiver which detects the electrical emissions from lightning activity. A proprietary algorithm in the AS3935 then converts the RF signal into an estimation of the distance to the head of the storm. The algorithm, which draws on extensive meteorological survey data, produces an estimated distance-to-storm calculation from 40km down to 1km, while rejecting disturbances from man-made signals such as motors and microwave ovens.

Portable lightning sensors can play a crucial role in keeping people from harm and protecting equipment from damage in locations that are prone to violent lightning storms. Unaided, humans can typically hear thunder at a distance of approximately 10km. This can often leave far too little time to find shelter when in the path of a fast-moving, highly-active electrical storm. In the case of being on a golf course or a baseball field, the extra time that a lightning sensor can provide could mean the difference between life and death.

The national weather service agencies today utilize sophisticated, large pole-mounted fixed sensors but portable lightning sensing equipment is not widely used by consumers or businesses today because it is cumbersome, inaccurate and prone to false alerts from man-made signals.

With the introduction of the AS3935 Franklin Lightning Sensor it is now possible for the first time to incorporate this innovative sensor technology into a wide variety of portable devices. With multiple low-power modes, a listening mode current consumption of 60A and housed in a 4mm x 4mm 16-pin MLPQ package, the AS3935 can easily be integrated into a variety of portable or outdoor devices targeting biking, hiking, marine, golfing, sporting events (football, soccer, baseball, etc.), and also in-building equipment such as uninterupted power supplies (UPS), power conditioners, telcom equipment, intelligent networks and smart grids needing early detection for use in surge damage prevention.
