Spec

• SparkFun lightning sensors can be installed at weather stations to detect lightning and ensure that dangerous weather is recognized. The onboard AS3935 is an Austrian AMS device that can detect lightning up to 40 km away with 1 km accuracy using a sensitive antenna tuned to detect lightning in the 500 kHz band. Lightning detectors can reliably exclude various sources of input that can ca*** false detections by default.
• In addition, you can *** a lightning detector library to make your device more robust against noise and false positives. You can also *** the Lightning Detection Library to configure storm sensing sensitivity for indoor and outdoor detection, the number of lightning strikes required to trigger an interrupt, and so on.　Get Started with the SparkFun Lightning Detector
