Description Attachments

The SparkFun Lightning Detector - AS3935 is a powerful tool that allows you to add lightning detection to your weather station, ensuring you stay informed about any potentially hazardous weather approaching. The AS3935 is designed to detect lightning from as far as 40km away, providing a 1km accuracy to the storm front. Its antenna is sensitively tuned to detect lightning events within the 500kHz band.

The SparkFun Lightning Detector is equipped with the ability to filter out false positives caused by various sources. The in-built lightning detector library allows you to customise the settings to enhance the chip's resilience to noise and false positives. This library also provides access to settings such as storm sensing sensitivity, allowing you to adjust the detector's performance based on whether you're indoors or outdoors. You can also define the number of lightning strikes required to trigger an interrupt.

The detector's features include a 40km range with a 1km accuracy in 14 steps, programmable detection levels, distance to storm estimation, a "disturber" rejection algorithm to filter out false events, indoor and outdoor settings, and an SPI interface. The operating range of the supply voltage is between 2.4V and 5.5V.

Various documents are available to help you get started with the SparkFun Lightning Detector, including a schematic, Eagle Files, a Hookup Guide, a Lightning Detector for the Trail, a Datasheet (AS3935), Library and Example Sketches, and a GitHub Hardware Repo.
