Lightning Detector

Posted on December 10th, 2016

Wouldn’t it be awesome to be able to sense and track lighting strikes using Arduino? Typically lightning detectors are very expensive, however, runtimeprojects has developed a cheap system for detecting lighting using only an Arduino Uno and a few resistors. Impressively the circuit can detect lightning as far away as 20km! At a basic level this lightning detector works by detecting changes in electromagnetic radiation using a small antenna which picks up small fluctuations in the electromagnetic spectrum, particularly at around 7kHz.
