Wireless Leaf & Soil Moisture/Temperature Station

Installation Manual

For Wireless Vantage Pro2

 and Vantage Pro2 Plus

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: 

• 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 tem-

perature 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 (rec-

ommended, see page 16)
