Elias The Sparkiest Introduction
The SparkFun Qwiic 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! The board supports both I2C and SPI, and so we've whipped out the Qwiic connector to make this easy to integrate into the Qwiic environment.
