Leaf Wetness Sensor for Davis Vantage Pro2

Detect and track leaf surface moisture with precision to protect your crops and ornamental plants. The Leaf Wetness Sensor for Davis Vantage Pro2 delivers a clear, unitless reading from 0 (dry) to 15 (saturated), helping you anticipate disease pressure, optimise irrigation, and time treatments with confidence. Its gold‑plated “artificial leaf” grid and weather‑resistant build ensure reliable, repeatable data in real field conditions. Easy to integrate with your Vantage Pro2 system via the compatible station or node, it arrives with a 12 m pre‑attached cable and a bracket that positions the sensor at 45° to mimic natural leaf posture. Choose proven agricultural insight backed by expert support from Stratosens.com.

Key Benefits and Applications

• Early disease risk detection — Use continuous wetness duration data to anticipate mildew, rust, blight and other foliar diseases, so you can act before outbreaks escalate.
• Smarter irrigation scheduling — Avoid unnecessary watering when foliage is already wet and reduce leaf wetness periods that favour pathogens, saving water and protecting plant health.
• Optimised spray timing — Plan treatments for when leaves are dry and conditions are favourable, improving coverage and efficacy while reducing waste.
• Canopy‑level insight — Mount within the crop canopy to capture true microclimate conditions that standard weather sensors can miss.
• Seamless Vantage Pro2 integration — Plug‑and‑play with the compatible Leaf & Soil Moisture/Temperature Station or EnviroMonitor Node, so you see leaf wetness alongside temperature, humidity, rain and more.
• Rugged, long‑life design — Gold‑plated grid and epoxy‑sealed electronics resist corrosion and weathering for dependable performance season after season.
• Actionable metrics — User‑selectable dry/wet thresholds and moisture‑hour totals translate raw readings into decisions you can trust.
• Research and commercial use — Ideal for universities, vineyards, orchards, greenhouses and precision‑ag projects requiring repeatable, comparable measurements.

Featured technical specifications

• Measurement scale — Unitless index from 0 to 15. Resolution of 1 step with typical accuracy of ±0.5 on the scale.
• Measurement principle — Artificial‑leaf electrical resistance using a gold‑plated etched grid on an epoxy‑glass substrate with bipolar low‑voltage excitation.
• Update and response — Sensor update interval typically 46 to 54 seconds with a time constant of approximately 2 seconds.
• Moisture‑hour accumulation — User can select the threshold at and above which moisture hours are accumulated for disease modelling.
• Cable and connector — Pre‑attached 12 m cable with modular RJ‑11 connector. Recommended maximum extension up to 61 m using 4‑conductor 26 AWG cable.
• Power and output — Powered by the host station at approximately 3 V DC with typical current draw of 100 µA and output of 2.5 to 3 V DC.
• Mounting bracket — Included bracket holds the sensor at 45° to simulate a natural leaf angle and promote runoff of excess water. Suitable for post, pipe or mounting arm installation.
• Compatibility — Works with Davis Vantage Pro2 via the Wireless or Cabled Leaf & Soil Moisture/Temperature Station (models 6345 or 6345CS). Also compatible with EnviroMonitor Node (model 6810).
• Station capacity — The Leaf & Soil Moisture/Temperature Station provides two dedicated leaf inputs, allowing the use of up to two leaf wetness sensors per station.
• Dimensions and mass — Sensor body approximately 102 × 58 × 58 mm with a sensing area of about 28 cm² and mass of roughly 0.4 kg.
• Materials — Grid made from copper with nickel and gold plating. Substrate is a glass‑reinforced, ceramic‑filled laminate. Mounting bracket is powder‑coated aluminium.
