Decagon’s leaf wetness sensor is standardized, calibrated, and engineered to detect wetness (presence and duration) and ice formation straight out of the box. No user calibration needed.
Each sensor is accurately factory-calibrated to detect the smallest amounts of water and/or ice on the leaf surface. The sensor surface is coated in a non-hygroscopic layer, removing chances of false wetness detection.
The sensor’s slim (0.65 mm) fiberglass construction closely estimates the total radiation balance of a standard leaf, so moisture will condense and evaporate from the sensor at a similar rate as it would on a normal leaf.
Get to the data immediately with the Em50 data loggers. Just install the sensor, plug it into the Em50, set the clock and measurement intervals, and start recording data. No programming needed.
Compatible with other data loggers (e.g. those manufactured by Campbell Scientific). Some programming is needed; however sample CSI programs are available on request.
Utah State University’s Plant, Soils, and Climate department has set up a complete weather station, and use the Leaf Wetness Sensor to record surface moisture. See the real-time data: View graph
