The RainWise Leaf Wetness Sensor consists of a gold plated printed circuit board with a pattern that conducts in the presence of moisture Any moisture, including dew, that collects on the board will cause a contact closure. When connected to a RainWise logger, this energizes a timer which records the “leaf wetness time” in hours and minutes.
RainWise, in cooperation with Purdue University, has developed a replaceable nylon screening that is fastened over the basic sensor. This screening retains moisture in the same way as a leaf, resulting in a very accurate simulation.
The standard mounting is the RainWise plug-in mount that matches our Monopod. The sensor can also be furnished with a small NEMA 4X enclosure equipped with a Monopod mount for remote installations.
The RainWise Leaf Wetness sensor guaranteed for five years.
