Wireless Leaf & Soil Moisture/Temperature Station
Installation Manual
For Wireless Vantage Pro2
The Wireless Leaf & Soil Moisture/Temperature Station (referred to in this document
as the Leaf/Soil Station) can be used with any Wireless Vantage Pro2 weather station
to measure leaf wetness, soil moisture, or temperature.
The following Vantage Pro2 console station configurations can be used with the
Leaf/Soil Station:
Station Type in
Console
Configuration
LEAF/SOIL Station
LEAF Station
SOIL Station
• Only one Leaf/Soil Station can be installed as a Leaf/Soil Station per Vantage Pro2
Weather Station.
• Two stations can be installed if one is configured as a Leaf Station and the other
station is configured as a Soil Station in the Vantage Pro2 console.
• Configured as a Leaf Station, the Station supports two leaf wetness sensors and
two temperature probes.
• Configured as a Soil Station, it supports up to four soil moisture sensors and
temperature probes.
Note:
In any station using soil moisture sensors, the corresponding temperature probe, if installed, will be
used for temperature compensation of the soil moisture sensor.
Tools for Setup
In addition to the components shown, you will need some or all of the following
materials:
• Adjustable wrench or 7/16" wrench
• Medium Phillips Screwdriver
• Ballpoint pen or paper clip (small pointed object of some kind)
• Drill and 3/16" (5 mm) drill bit (if mounting on a vertical surface)
• Stepped Sensor Installation Tool for Soil Moisture and Temperature Sensors

- Page 9 Testing Transmission from Proposed Location It is very important to test reception from the proposed location before permanently mounting the Leaf/Soil Station. • Place the shelter at the intended mounting site, or have someone hold it there, so you can walk around with the console/receiver for a few minutes. Rotating the antenna so that the transmitting and receiving antennas are parallel to each other may help to improve reception.
