Industrial Leaf Wetness and Temperature Sensor (A), MODBUS-RTU RS485

S-YM-01 Sensor comes in the shape of a leaf, simulating the wetness and temperature on a real leaf. It measures leaf wetness and temperature, providing insights for pest control, irrigation, and other management that are optimal for plant and crop health. The sensor is IP68 rated and the output signal can be RS485, Analog Voltage, or Analog Current. It can be widely used in applications of farming in the outdoor, in greenhouses, plant research, and other scenarios where leaf wetness and temperature are important.

PRODUCT DETAILS

Note

Industrial Leaf Wetness and Temperature Sensor comes in two versions. The main difference is in the cable connector. Please choose the version that best suits your needs: 
   
(1) Version B: with a waterproof aviation connector. This version saves you time in deployment as you won't have to use screws to connect the cable to the data logger. And it can be used with SenseCAP Sensor Hub 4G Data Logger instantly with ease.
   
(2) Version A: with hook-up wires.

    

Features

  • Supporting multiple output Interfaces: MODBUS-RTU RS485, analog voltage, and analog current
  • Simulating the real leaf thermal resistance by sensing shape and thickness
  • Strong robustness: water, ice, foggy detection
  • Industrial-grade design: IP68 rated, waterproof and dustproof, suitable for harsh environments
  • Industry standards: high accuracy with excellent stability
  • Reverse power protection and Built-in TVS/ESD protection
             

Leaf wetness is an important indicator of the infection of pathogens on the leaves. The amount of moisture on the leaf surface makes it easy to be infected by fungal and bacterial diseases. During the period of pathogen infection, if the leaf surface is completely wet, it is easier for the diseases to spread, which will ultimately bring damages to the leaf structures and plant health.

         

The leaf wetness & temperature sensor can measure the presence and duration of the moisture and temperature on the leaf surface. Thus, it can provide information about wetness (from dew, rain, pesticide, and irrigation, etc.) and the temperature of the leaves. With these data available, farmers can make better decisions for irrigation, pest control, and other measures to make the plants and crops grow better.  

      

Leaf wetness is a parameter that describes the amount of dew and precipitation left on surfaces. It is used for monitoring leaf moisture for agricultural purposes, such as fungus and disease control, for control of irrigation systems, and for detection of fog and dew conditions, and for early detection of rainfall.

          

This industrial Leaf Wetness and Temperature Sensor comes in the shape of a leaf, and it simulates the wetness and temperature of a real leaf. To make the sensor more robust, it is sealed with a resin packaged plastic body, which makes it waterproof and suitable for long-time monitoring, even in outdoor harsh environments. The sensor itself tries to mimic the thermal resistance of a real leaf so that the water on the sensor condenses and evaporates at the same rate as on a real leaf. The sensor determines the wetness by measuring the change of the relative permittivity. The measurement value is proportional to the percentage of the sensing area covered with water. The output signal can be RS485, Analog Voltage, or Analog Current, and can be fed into a data logger.
