Seeed Studio Industrial Leaf Wetness & Temperature Sensor

Seeed Studio Industrial Leaf Wetness and Temperature Sensor is designed to provide insights for pest control, irrigation, other management that are optimal for plant and crop health. This sensor comes in the shape of a leaf and simulates the wetness and temperature on a real leaf. The leaf wetness and temperature sensor is IP68 rated and the output signal can be RS485, analog voltage, or analog current. The leaf wetness is a parameter that describes the amount of dew and precipitation left on surfaces. This is helpful for monitoring leaf moisture for agricultural purposes such as fungus and disease control. This sensor features reverse power protection and built-in TVS/ESD protection. Applications include science research, smart agriculture, irrigation management, pest control, bacteria prevention, horticulture, and forestry management.
