1. A moisture sensor comprising:
a) a case which is at least water resistant and has an exterior, said case having an upper portion and a lower portion that is a circuit board;
b) a plurality of sensing contacts on the exterior of the case, said plurality including a first plurality positioned to sense moisture when the case is in a generally horizontal position and a second plurality positioned to sense moisture when the case is in an inclined position;
c) resistance sensing circuits to allow measurements of electrical resistance between at least two sensing contacts representing a relative level of moisture present near the plurality of sensing contacts;
d) a timer to cause periodic measurements of electrical resistance between at least two sensing contacts;
e) a transmitter for periodically transmitting electrical resistance measurements; and
f) wherein a plurality of the sensing contacts are fasteners that secure the case upper portion to the case lower portion.
