LEAF WETNESS SENSOR
INSTALLATION MANUAL
The leaf wetness sensor enables the Vantage Pro2™ Wireless Leaf & Soil Moisture /Temperature Station (#6345) to detect the presence of surface moisture on
foliage and calculate the duration of wetness. When moisture is present, the
sensor detects an electrical resistance change between the gold-plated elements of the grid. This is displayed by the Vantage Pro2 console as a value
between 0 (dry) and 15 (wet). With WeatherLink
tural/Turf Management Module (#6511), you may select your own wetness
threshold; the software will then calculate leaf-wet hours.

INSTALLING THE SENSOR
Connecting Leaf Wetness Sensors
1. Run the sensor cables up through the grommets on the bottom of the station
housing.
2. Insert the sensor cable modular plug into the Leaf 1 or Leaf 2 modular connector.

Finishing the Sensor Connections
1. Secure sensor cables to the cable
tie mounts located next to the
grommets.
2. To prevent fraying or cutting of cables,
secure them so they will not whip about in
the wind. Secure a cable to a metal pole by
wrapping electrical tape around them both.
Make sure cables are secure by placing
clips or ties approximately every 3 – 5' (1 –
1.6 m)
Connecting Leaf Wetness Sensors
When tightening
cable tie, make sure
cables are on top of
cable tie mount.

Note: Do not use metal staples or a staple gun to secure cables. Metal staples — especially
when installed with a staple gun — have a tendency to cut the cables.
