Based on the AMS reference design, this is a breakout board for the AS3935 digital lightning sensor. With a specially tuned antenna, SPI or I2C interfacing and a wide 2.4V to 5.5V standard operating range, this innovative sensor is designed to interface with most current development systems and boards. This includes all of the current Arduino modules! The AS3935 Franklin Lightning Detector gives you lightning detection for your next weather project. This sensor is capable of detecting lightning up to 40 km away with an accuracy of 1km to the storm front! On the product is a sensitive antenna tuned to pick up lightning events in the 500kHz band. When sensing an event the AS3935 utilizes an interrupt to the interrupt pin, distinguishes between false and real lightning events, and has a number of features to help calibrate lightning detection. For example, there are settings for detecting from indoors or detecting from outdoors, settings to change the threshold for false events, and settings to be alerted only after a certain number of lightning strikes to name a few. We’ve also written an Arduino Library to get you prepared for that upcoming storm! The product is capable of communicating over SPI or I2C and sports a Qwiic connector for fast implementation without the need for soldering.
