Product Description
LWS-10 Leaf Wetness Sensor，RS485，0-2V，4-20mA
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.
■ Integrated with leaf wetness and temperature measurement
■ Output Interface with RS485, Voltage, Current
■ Mimics the real leaf thermal resistance by sensing shape and thickness
■ Water, ice, foggy detection
■ Water proof to IP68 ratings
■ High accuracy with excellent stability
■ Reverse power protection and Built-in TVS/ESD protection
