Detect Leaf Wetness and Ice Formation

Decagon's LWS leaf wetness sensor is standardised, 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 ice on the leaf surface. The sensor surface coating is non-hygroscopic, eliminating false wetness detection.

Mimics a Real Leaf

The sensor's thin (0.65mm) fibreglass construction closely approximates the heat capacity of a typical leaf, and its overall radiation balance closely matches that of a healthy 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 (including Campbell Scientific). Some programming required; sample programs 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.
