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.
