Gurus,
I'm working on a homemade weather station and I would like to detect lightning. Does anyone have a suggestion for a cheap and easy solution? This is a learning project for me so I don't want to buy a prefabricated system. It's a processor based system that feeds the data to a PC running Microsofts version of Windows with a program written in C or C++ . Any thoughts?
I think you would have to employ some more sophisticated processing to handle false alarms. you may need to do some processing to filter out patterns based on time and shape. you may even require quite some sensors to allow for that (e.g. increase you resolution). there are cheap light sensors out there that connect to your processor's I2C bus, so no ADC is required actually.
