Hi, I'm studying electronics and I've to make a final project to finish my
studies.
I've saw an artifact that is used to measure the grass density (in Kg/hect)
and I'm very interested about it.
It's composed by a stick of aprox. 1.5 meters with an aluminum sphere in one
side and a small computer on the other (used to show, log and average the
measures).
Apparently, what this device does is to measure capacitance, and the grass
in the field is used as the dielectric (the same principle of a humidity
meter I think).
My question is against what it measures capacitance (against ground?) and
how it does it.
I would appreciate a lot some information or guidance on the subject (I've
been searching the net and found almost none information)
Thanks in advance.
