The leaf wetness sensor enables the Vantage Pro2™ Wireless Leaf & Soil Mois-
ture /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 ele-
ments of the grid. This is displayed by the Vantage Pro2 console as a value
between 0 (dry) and 15 (wet). With WeatherLink
®
software and the Agricul-
tural/Turf Management Module (#6511), you may select your own wetness
threshold; the software will then calculate leaf-wet hours.

- Securing Sensor Cables in the Station
- 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 ...
- Securing Cables with Clips and Ties
- 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.
