Cảm biến đo độ ẩm ướt Campbell Scientific LWS-L

Overview

The LWS, manufactured by Decagon Devices, is a leaf-wetness sensor that can detect small amounts of water or ice on the sensor surface. It is designed to be deployed either in the canopy or on a weather station mast. All of our dataloggers can measure its output signal.

Benefits and Features

  • Imitates characteristics of a leaf

  • Does not require painting or calibration of individual sensors

  • Detects trace amounts of water or ice on the leaf surface

  • Compatible with all Campbell Scientific dataloggers (including the CR200(X) series)

  • Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network

Detailed Description

The LWS measures the dielectric constant of the sensor’s upper surface. This method allows the sensor to detect the presence of water or ice anywhere on the sensor’s surface.
