The leaf wetness sensor enables the GroWeather™ to detect the presence of
surface moisture on foliage and calculate the duration of wetness. When mois-
ture is present, the sensor detects an electrical resistance change between the
gold-plated elements of the grid. This is displayed by the GroWeather console
as a value between 0 (dry) and 15 (wet). Using the GroWeatherLink
®
software,
you may select your own wetness threshold; the software will then calculate
leaf-wet hours.
