+Basic plant sensor kit which currently outputs;

+Hardware interface based loosly on recollection of Martin Howse's experiements with the Wheatstone Bridge (during piskel08) and incorporates parts of a design published by Rob Faludi ([[http://www.faludi.com/2006/11/02/moisture-sensor-circuit/|moisture circuit]]) which was in turn based on a design by Forrest Mims, with nods to L. George Lawrence, Botanicalls and the long and tangled path from Jagdish Chandra Bose.
