SparkFun AS3935 Lightning Detector Hookup Guide (v20)

Introduction

Note: This tutorial was written for v20 of the AS3935 lightning detector. For information on the previous version of the hookup guide, you will need to head over to the older tutorial.

The SparkFun AS3935 Lightning Detector adds lightning detection to your next weather station or to your next bike ride. Are you worried about the looming clouds in the distance, how far away is that storm exactly? The lightning detector can tell you the distance to the front of the storm 40 km away with an accuracy of 1km. It has false positive rejection and comes with many configurable features. To get at those features we have written a library that gives you access to settings such as storm sensing sensitivity, when detecting indoors vs outdoors, or the number of lightning strikes needed to trigger an interrupt! Revision 2.0 of the board is SPI only*, with the caveat that if you wanted to use I²C, all the parts are there but it is NOT supported by SparkFun.
