A wireless soil moisture meter network includes a central display unit and a
plurality
of remote sensor units. Each sensor unit uses a probe to measure moisture content
in soil, and uses a wireless transmitter to transmit the measurement through a
wireless channel to the central display unit. The central display unit receives
and displays the measurement in a format selectable by a user. The user may add
to or remove from the network a sensor unit using a user interface of the central
display unit.
