The Leaf Wetness Sensor is standarised, calibrated, and designed to detect wetness and ice after installation. With denser leaf vein patterns on the surface, smaller droplets can be detected and the measurement is more sensitive. The sensor surface coating is non-hygroscopic, eliminating false wetness detection.

This leaf surface wetness sensor working principle is to measure wetness through the change of the leaf surface dielectric constant with good sensitivity, it can detect trace water or ice residues on the surface of leaves. The appearance is completely waterproof and can be used outdoors for a long time. Easy to use, widely used in green houses, laboratories, breeding, production environments, artificial climate rooms, and other plants or object surface humidity measurement.
