I’ve ordered the AS3935 Sparkfun Lightning detector via a reseller.
My question is, is the lightning sensor calibrated from factory? If so, is there any capacitance number written on the box?
This is from our hookup guide:
“The lightning detector can tell you the distance to the front of the storm 40 km away with an accuracy of 1km. It has false positive rejection and comes with many configurable features. To get at those features we have written a library that gives you access to settings such as storm sensing sensitivity, when detecting indoors vs outdoors, or the number of lightning strikes needed to trigger an interrupt!”
The modes are calibrated differently depending on what you chose, the guide covers most of it

I think you mean this line:
As a good starting point, we’ve found that the resonance frequency of our manufactured boards start at about ~496kHz. The datasheet specifies that the resonance frequency should be within 3.5 percent above or below 500mHz for optimal lightning detection. Our boards ship within less than one percent of that value.
Right? 
I mean everything linked 
OK, will see when it’s here if it works out of the box.
