Combined magnetometer and cloud detector PCBs

PCBs for a combined magnetometer and/or cloud detector.


Magnetic field measurements are taken from a Stefan-Mayer FLC100 sensor. Cloud detection is by measuring the 'sky' temperature. Low temperatures suggest clear skies and higher temperatures indicate the presence of cloud. A humidity sensor is also fitted to help predict the clear sky and cloudy sky temperatures. The Embedded Adventures lightning sensor module can also be fitted.


The sensor shield in intended to fit on my Calunium Arduino clone but it can also be used with an Arduino Mega2560. Design files, firmware and software are all open source (Creative Commons Attribution-ShareAlike 3.0 for hardware, GNU GPL v2 for software).
