Leaf Sensor (SMKB-FWS1)
SMKB-FWS1 leaf (Foliar) W etness Sensor is an important tool for observing and studying leaf(Foliar) wetness, preventing pests and diseases, and spraying sprinkler control.The accurate measurement of the moisture content of the leaf(Foliar) surface can be used to monitor the trace moisture or ice crystal residue. The shape of the sensor is simulated by the blade, which can simulate the characteristics of the leaf(Foliar) surface, so that it can reflect the situation of the leaf (Foliar) surface more accurately . By measuring the variation of the dielectric constant of the upper surface of the blade, the mist, water vapor and ice can be measured.
