LWS Leaf Wetness Sensor
- Measurements:
- Applications:
Detect Leaf Wetness and Ice Formation
Decagon's LWS leaf wetness sensor is standardized, calibrated, and designed to detect wetness (presence and duration) and ice formation right out of the box. No painting, baking, or user calibration required.
Sensitivity without False Positives
Each sensor is precisely factory-calibrated to detect tiny amounts of water and/or ice on the leaf surface. The sensor surface coating is non-hygroscopic, eliminating false wetness detection.
Mimics a Real Leaf
The sensor's thin (0.65 mm) fiberglass construction closely approximates the overall radiation balance of a healthy leaf, so moisture will condense and evaporate from the sensor at the same rate as it would on a normal leaf.
Plug and Read
Get straight to the data with the Em50 series of data loggers. Just install the sensor, plug it into the Em50, set the clock and measurement intervals, and start logging leaf wetness data. No programming required.
Want to Use a Different Logger? No Problem
Compatible with other data loggers (e.g. those manufactured by Campbell Scientific). Some programming is required; sample CSI programs are available on request.
Use the Leaf Wetness Sensor:
- To predict when to spray crops.
- To quantify water storage in the plant canopy.
- In studying and monitoring crops for foliar diseases including rust and blight.
