The ADCON Leaf Wetness Sensor was developed to provide users with a robust and low-maintenance alternative to the traditional style sensors using sheets of paper or human or animal hair. A grid of conductive tracks, etched onto a Teflon-coated ceramic plate reliably simulates the surface of a leaf and outputs a range of readings between 0 and 10.
In Adcon’s addVANTAGE Pro software the interpretation of the sensor’s output is based on empirical observation of the behavior of moisture on large-leaved plants. In all disease models currently implemented in addVANTAGE Pro 5.x and 6.x sensor values between 0 and 3 are interpreted as dry, whilevalues from 4 to 10 represent wet. For leaves with particular wetting patterns, or for disease models requiring intermediate steps between wet and dry different sensor drivers can easily be implemented.
