1. A method of establishing a wireless soil moisture meter network, the method comprising:
- (a) using a portable central display unit to assign a wireless channel number to a remote sensor;
(b) upon the activation of a synch mode, placing the central display unit in a wait state until a predefined bit sequence is received; and
(c) enabling the sensor to send the predefined bit sequence and a unique identifier of the sensor to the central display unit.

Abstract
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.

7. A method for establishing a network between a central display unit and an environmental sensor, comprising the steps of:
-
(a) selecting a channel for the sensor;
(b) activating a “
wait”
mode on the display unit;
(c) transmitting a sensor identifier from the sensor to the display unit; and
(d) storing the sensor identifier and corresponding channel in a memory device of the display unit. - View Dependent Claims (8)

9. A method for establishing a network between a central display unit, a first environmental sensor, and a second environmental sensor, comprising the steps of:
-
(a) activating a “
wait”
state for the display unit and transmitting a predefined sequence and a first sensor ID from the first sensor to the display unit;
(b) upon receiving the predefined sequence and the first sensor ID, recording the presence of the first sensor in a memory device;
(c) activating a “
wait”
state for the display unit and transmitting the predefined sequence and a second sensor ID from the second sensor to the display unit; and
(d) upon receiving the predefined sequence and the second sensor ID, recording the presence of the second sensor in the memory device. - View Dependent Claims (10, 11, 12)

13. A wireless network comprising:
-
a first environmental sensor unit including a sensor adapted to measure an environmental condition, a transmitter adapted to transmit a data stream through a wireless channel, and a button adapted to cause the transmitter to transmit a predefined sequence and a first sensor ID upon activation;
a second environmental sensor unit including a sensor adapted to measure an environmental condition, a transmitter adapted to transmit a data stream through a wireless channel, and a button adapted to cause the transmitter to transmit the predefined sequence and a second sensor ID upon activation; and
a central display unit including a receiver adapted to receive a data stream through a wireless channel, a memory device, and a processor having an “
add channel”
mode in which the processor is adapted to record the presence of the first environment sensor unit in the memory device upon the receipt of the predefined sequence and the first sensor ID and further adapted to record the presence of the second environment sensor unit in the memory device upon the receipt of the predefined sequence and the second sensor ID. - View Dependent Claims (14, 15, 16, 17)
