The amount of moisture on the leaf surface makes it easy to be infected by fungal and bacterial diseases. It is used for monitoring leaf moisture for agricultural purposes, such as fungus and disease control, for control of irrigation systems, for detection of fog and dew conditions, and for early detection of rainfall.\u003c\/p\u003e\n\u003cp\u003eThe \u003ca href=\"\/collections\/seeed\" title=\"Seeed Products\"\u003eSeeed\u003c\/a\u003e \u003cstrong\u003eIndustrial Leaf Wetness \u0026amp; Temperature Sensor measures moisture presence, duration, and temperature on leaf surfaces. It provides reliable data on wetness from sources such as dew, rain, irrigation, or pesticides, alongside leaf temperature\u003c\/strong\u003e. With this data available, farmers can make better decisions for irrigation, pest control, and other measures to make the plants and crops grow better.\u003c\/p\u003e\n\u003cp\u003eThis Seeed industrial Leaf Wetness and Temperature Sensor \u003cstrong\u003ecomes in the shape of a leaf\u003c\/strong\u003e, and it \u003cstrong\u003esimulates the wetness and temperature of a real leaf\u003c\/strong\u003e. To make the sensor more robust, it is sealed with a resin-packaged plastic body, which makes it \u003cstrong\u003ewaterproof\u003c\/strong\u003e and suitable for long-time monitoring, even in outdoor harsh environments.\u003c\/p\u003e\n\u003cp\u003eThe sensor itself tries to \u003cstrong\u003emimic the thermal resistance of a real leaf\u003c\/strong\u003e so that the water on the sensor condenses and evaporates at the same rate as on a real leaf. The sensor \u003cstrong\u003edetermines the wetness\u003c\/strong\u003e by measuring the change in the relative permittivity. The measurement value is proportional to the percentage of the sensing area covered with water. \u003cstrong\u003eThe output signal can be RS485, Analogue Voltage, or Analogue Current, and can be fed into a data logger.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt can be used with the \u003ca href=\"\/products\/sensecap-s2100-lorawan-data-logger\" title=\"SenseCAP S2100 - LoRaWAN Data
