Abstract:
1. A moisture detector for detecting moisture in potting media or soil for plants, comprising: a body formed to represent a creature having at least one eye; a processor housed in said body; probes in electrical connection with said processor and extending from said body, said probes being adapted to send an electrical signal to said processor, said signal from said probes indicating a level of moisture proximate to said probes, said processor adapted to receive said signal from said probes; a power source housed in said body and in electrical connection with said processor; and at least one light emitting diode carried by said body at said at least one eye and in electrical connection with said processor and said power source so that, when said probes are inserted into soil and said level of moisture in said soil is insufficient for a given plant, and said signal from said probes so indicates, said processor causes said power source to light said light-emitting diode, and wherein said processor is adapted to extract a signal from said probes by sending a signal to said probes, and further comprises means for evaluating a return signal that is generated by said probes and returned to said processor.
