Franklin Lightning Sensor™
Lightning Sensor IC with Embedded Distance Estimation Algorithm
The AS3935 Franklin Lightning Sensor™ is the world’s 1st lightning sensing IC that was designed for low power, portable or fixed wire-line applications.
Utilizing a sensitive RF receiver and integrated proprietary algorithm, the Franklin Lightning Sensor™ detects the electrical emissions from lightning activity and then provides for an estimation of the distance to the head of the storm from 40km away down to 1km, while rejecting disturbances from man-made signals such as motors and microwave ovens.
This advanced warning capability alerts users so that precautions can be taken.
FEATURES
- Detection of both cloud to ground and cloud to cloud lightning activity within a 40km range
- Intelligent algorithm provides for false disturber rejection
- Supply voltage range of 2.4-5.5V with power down, listening and active power modes
- Antenna auto tuning
- Small MLPW-16 (4mmx4mm) package
BENEFITS
- Provides early warning beyond human senses and gives distance estimation to head of storm
- Algorithm reduces false indications
- Selectable power modes make it suitable for low power portable devices
- Antenna auto tuning provides for optimal receive performance
- Suitable for portable battery powered applications
APPLICATIONS
