Agriculture-oriented technical toys:

As an example, grab a few of the FullStop wetting front detectors, replace the mechanical float+indicator with a reed switch in the ground, with the wires coming up along with the sample hose.  Thus the wetting front detector can be entirely under the ground, allowing the hose+wires to surface outside the raised bed, allowing chook tractors to be manoeuvred over the bed without disrupting the telemetry.

Hook a few of these up to a small (solar/battery powered) controller in the garden, which then transmits data back to the base station (wifi? ethernet? IR link?)… profit?
