Leaf Wetness Sensor
This RS-WS-*-YM-1-EX leaf wetness sensor is standardized, calibrated, and designed to detect wetness and ice after installation. With denser leaf vein patterns on the surface, smaller droplets can be detected and the measurement is more sensitive. The sensor surface coating is non-hygroscopic, eliminating false wetness detection.
- Model: RS-WS-*-YM-1-EX
- MOQ: 1 PCS
- Delivery date: within 24 hours
- Price: $31.5
About - Leaf Wetness Sensor
Description
The leaf wetness sensor is equipped with a high-precision thermistor for temperature measurement. Its working principle is based on detecting changes in the dielectric constant to measure humidity.
The sensor is designed in the shape of a leaf, realistically simulating the characteristics of a plant leaf surface. With high sensitivity, it can detect even trace amounts of water residue on the leaf surface.
Featuring a waterproof design and low power consumption, the leaf wetness sensor supports long-term continuous monitoring. It is easy to install and can be directly hung on tree branches.
Our leaf wetness sensor is widely used for measuring plant surface humidity in greenhouses, laboratories, livestock farms, agricultural fields, and gardens.
Features
- Simulates natural leaf characteristics for fast and accurate temperature and humidity measurement.
- High-density vein design (15 veins/cm) enables the detection of finer water droplets with greater sensitivity.
- High humidity sensitivity, accurately detects moisture on the leaf surface.
- High precision, fast response, and excellent interchangeability.
- Epoxy resin encapsulation, waterproof and moisture-resistant, ensuring longer service life.

FAQs - Leaf Wetness Sensor
What is leaf wetness?
Leaf wetness refers to the amount of dew and precipitation remaining on the surface. The level of leaf wetness has an important influence on plant infection pathogens. When the plant leaf surface wetness is too high, it will increase the breeding probability of field bacteria and increase the risk of leaf infection. Once the plant is infected with the disease bacteria, the disease bacteria will damage the leaf surface structure, which is not conducive to the growth and development of the plant.
What is leaf wetness sensor?
The leaf surface wetness sensor is an important tool for observing and studying the leaf surface wetness, preventing diseases and insect pests, and controlling sprinkler irrigation. The leaf surface wetness sensor can accurately measure the leaf surface wetness, and can monitor the trace moisture or ice crystal residues on the leaf surface.
How to install the leaf wetness sensor?
Place the leaf wetness sensor next to the crops or leaves, use a non-metallic wire to pass through the small hole in the front of the sensor, hang it on the branches of the tree, and fix the sensor on the branches or stems with iron wires. The angle of inclination and orientation are close to those of real plants. The ideal leaf wetness sensor should be installed at a distance of more than 1 meter from the ground. It can be hung above the plants and avoid direct sunlight as much as possible.
Where is the application of leaf wetness sensor?
- Predict when to spray crops.
- Quantify the water storage in the plant canopy.
- Research and monitor crop leaf diseases, including rust and fusarium wilt.
How to maintain the leaf wetness sensor?
Clean the equipment at least once a month during continuous work, mainly to clean the ice, snow, dust, etc. deposited on the surface of the equipment.
What is the warranty of leaf wetness sensor?
When used in a normal environment, we will provide you with a two-year warranty.
How to view measurement data?
This leaf wetness sensor uses rs485 or analog signal transmission, and the measurement data can be directly uploaded to the free cloud platform we provide you. You can view the data in real-time remotely through a computer or mobile phone.
