LWS10 measures leaf wetness. It sealed with resin packaged plastic body can be used for long time monitor. Wetness measurement value is proportional to the percentage of sensing area covered with water. The output signal can be RS485, Analog Voltage or Analog Current. The sensor is applicable for science research, bacteria prevention, foliage dressing spraying, greenhouse, smart agriculture etc.
