AS3935

AS3935 Lightning Sensor can detect lightning and display the distance and intensity of the lightning without the disturbance of electric arc and noise.
It can be set as indoor or outdoor mode.

Summary

Input commands and read data from AS3935 modules

Feature

1. Lightning sensor warns of lightning storm activity within a radius of 40km
   
2. Distance estimation to the head of the storm from overhead to 40km in 15 steps
   
3. Detects both cloud-to-ground and intra-cloud(cloud-to-cloud) flashes
   
4. Embedded man-made disturber rejection algorithm
   
5. Programmable detection levels enable threshold setting for optimal controls
   
6. Three i2c interfaces, switch freely to avoid site conflicts
   

Installation

Download the library ZIP file and unzip it to the Arduino folder of the library.
