High-precision measurement using capacitance method, analog voltage output for both front and back surfaces.
The HD3910 leaf surface moisture sensor is a sensor that detects water droplets on the sensing surface. It is designed to accurately reproduce the thermodynamic effects of leaves. The moisture level of the leaves provides essential information for determining optimal sterilization and disinfection treatments to prevent mold and bacterial infections that could harm plants and crops with water droplets on their leaves. Since the drying time differs between the front and back surfaces of the leaves, the HD3910 sensor's sensing surfaces on both sides, which can detect moisture levels on both sides of the leaves, are an important feature. To ensure long-term use of the sensor, a special treatment is applied to its surface to withstand the chemical factors present in the atmosphere and pesticides.
