Intelligent Programmable Lightning Sensor in the form of an AS3935 integrated circuit capable of recording the presence and subsequent approach of potentially dangerous lightning action up to 40km. It supports a number of possible configurations and is capable of evaluating events outside and inside buildings. It all depends on the profits setting in the appropriate registry. The AS3935 can detect and exclude from the analysis the interference of common, artificially produced sources (motors, fluorescent lighting, microwave ovens, etc.). Suitable for
weather stations, sports electronic equipment, etc.

Franklin Lightning Sensor Lightning Detector lets you:
Timely warning before thunderstorms within 40 km
Estimated distance of front of storm (1km ~ 40km, 14 steps)
Blink detection between cloud and ground, cloud-cloud type
Sophisticated algorithm to suppress false alarms
Adjustable detection levels, threshold definition for optimal operation
SPI and I2C interface, control and readout of the registry
Automatic tuning of the antenna
Power-down, listening, active modes
