RZ Wireless SSN (Crossbow SSM1000CB) Installation Instructions

RZ Wireless Soil Sensor Nodes are the crux of the RZ wireless soil monitoring system. The SSN

is a battery operated node that goes to sleep periodically to conserve energy. For the first two

hours after it is turned on it will wake up every 30 seconds (report rate), take measurements from

each of its 2 sensors (each sensor measures temperature, moisture and conductivity

simultaneously). It then transmits that information to a nearby CCN. After the SSN has been on

for 2 hours the report rate will change to every 10 minutes. The report rate can be managed using

the RZ Wireless Application (see the RZ Wireless User’s Guide for more information)

Note that the instruction for SSN installation requires knowledge of the soil type – sand,

silt or clay. The installer should verify the soil type with the Site superintendent before

installing SSNs. Soil types for each node is set using the RZ Wireless application

The step-by-step instructions for an SSN install include the following:

• Collect items needed for the install.

• Set SSN ID

• Install SSN

• Record SSN installation information

• Verify the SSN installation

1. Collect Items Needed for the Install Steps: a. Determine the hole(s) at which SSNs are to be installed. b. Consult the site survey to determine the number of SSNs needed for the hole (plus 1 or 2 spares). c. Consult the site survey to determine the depth for each sensor (upper and lower) d. Collect needed SSNs and all other equipment, materials and tools as listed in Table 3. e. Transport all items to the specified hole. 2.

d. Record on the box and also enter the ID number into a log. e. Edit the joinmap.xtbl file so that the SSN IDs match the numbering scheme for each hole f. Note the new ID number on the box and the hole/location that it is detained for. g. Restart the RZ wireless processes and restart the SSN. The new ID should be “beeped-out”. h. The SSN is now ready to be installed. 3. Installing each SSN Steps: a. Using the site survey, confirm the specific SSN location with Site superintendent or designee. b.

soil as specified for the grass type (2” and 4” for cool season grasses, 1” and 3” for warm season grasses). Position the radio node in the adjoining 4”-cup hole. • For an AST sensor: Position the radio node in one of the freshly cut 4” cup holes.

Use the sniffer installed on your lap-top to verify that the SSN can be heard. The sniffer will show a “one-hop” message type with the origin equal to the Node ID. h. Use the GPS device (or measure the distance to the sensor from 2sprinkler heads to determine the sensor location. i. Record the sensor location in a log to be kept with the superintendent.
