Qwiic AS3935 Lightning Detector

Added to your shopping cart

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! Check under the documents tab under Library and Example Sketches.

The product is capable of communicating over SPI or I2C and sports a Qwiic connector for fast implementation without the need for soldering.
