Product Description
The system consists of a weatherproof enclosure which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and Leaf Wetness, Air Temperature and Humidity sensors (one each). For the most accurate disease prediction the leaf wetness sensor, designed to mimic the surface area of a leaf, use electrical resistance to measure the level of surface moisture on foliage, whether caused by rainfall, dew, or spray. The leaf wetness sensor enables the data logger 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 and record by the data logger as a value between 0% to 100% 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.
