Hi All,   I was so happy with my sensor, over the last few day.  I had a =
major problem with thermos, which disappeared with my insulated box.   =
This question has to do with weather changes, and why that effects =
noise.
A day ago the tract was quiet at night and a little bit of noise during =
the day time and city activities.
Many hours ago a cold front came thru, arriving at 8:00 pm with winds.   =
The trace went from quite to noisy several hour ahead of the front.  You =
could look at the trace and see the change as the front got closer.   =
This weather should move out in the next 24 hours.  So I expect things =
will go back to normal.

I don't understand, what is stimulating the sensor.
1.  Does it respond to barometric pressure changes?
2.  When wind is part of the storm, and the wind moves the trees, is =
this transferred thru the ground to the sensors as earth movements?
3.  Would a bolt of lightening be displayed on the trace?

As a front approaches it is like the atmosphere starts to fill with =
electromagnet noise.  I'm just trying to understand what creates it.
Inside the garage and inside the box it seem so isolated, no wind, no =
air current, no vibrations or physical movements. Yet the sensor can see =
a front hours before it arrives.
