4-20mA Analog Leaf Dew Detector High Sensitivity 0.1%Rh Resolution Orchard Plant Leaf Temperature Transmitter

Finer vein spacing of 15 lines per cm captures smaller droplets than lower-density designs, enabling earlier disease risk detection from light dew or mist before visible moisture accumulates.

Physical shape and surface texture mimic actual plant leaves, ensuring the sensor intercepts and retains moisture in the same way a real leaf would under identical field conditions.

Sensor surface is treated with a non-hygroscopic coating that prevents the material itself from absorbing ambient humidity, ensuring only actual surface water or ice triggers a wetness reading.

Capable of identifying both liquid water and frozen ice crystals on the sensing surface, extending reliable monitoring capability through freezing nights and early morning frost events.

Integrated thermistor delivers plus or minus 0.5 degrees C accuracy and 0.1 degrees C resolution across -40 to 80 degrees C alongside wetness detection in a single compact unit.

Sensing method measures changes in dielectric constant rather than direct conductivity, delivering high humidity sensitivity and accurate detection of trace moisture on the leaf surface.

Full epoxy potting with flame-retardant material and IP67 protection enables long-term outdoor deployment in rain, heavy dew, and high-humidity field environments without waterproofing degradation.

Small mounting hole at the front allows direct suspension on tree branches using non-metallic wire, with recommended height above 1 meter above ground to match real plant canopy conditions.

RS485 model accepts 5 to 30VDC, while analog variants cover 10 to 30VDC and 18 to 30VDC respectively, adapting to diverse field power supplies without additional voltage conversion.

Backed by a 2-year warranty under normal use, with free cloud platform access for real-time remote data viewing and historical records via PC browser or mobile app.
