Leaf Temperature and Humidity Sensor For Smart Agriculture Leaf Moisture Recorder RS485

Product introduction：

Leaf wetness sensor, also known as a foliage wetness detector or leaf moisture sensor, is an instrument designed to measure the wetness or moisture level on plant leaves. This sensor plays a crucial role in various agricultural and environmental applications by providing valuable insights into plant health, disease prevention, and irrigation management.

The leaf wetness sensor can accurately measure the leaf surface humidity, and can monitor the trace moisture or ice crystal residue on the leaf surface. The shape of the sensor adopts the imitation blade design, which simulates the characteristics of the page, so it can more accurately reflect the situation of the leaf environment. It measures the presence of water or ice by imitating the change in the dielectric constant of the upper surface of the blade medium. Low power consumption enables long-term uninterrupted monitoring. It is easy to install and can be hung on the greenhouse of the greenhouse or on the mast of the weather station.

The level of humidity on the surface of plant leaves has an important effect on their infection with pathogens. High humidity on the surface of leaves is easily infected by bacteria or fungi, and during this period, if the leaves are completely wet, the pathogens will be further infected, and when the pathogens are infected for a long period of time, the structure of the leaves will be destroyed.

If the temperature and humidity of the plant leaf surface can be detected for a long time, it can not only prevent bacterial or fungal infection, but also control the holding time of pesticide droplets for pest control, so as to take relevant protective measures for plants or crops. So the study of foliar temperature and humidity sensors has the following important significance:

1.Understanding plant growth and development and conducting certain research on it

2.Prevent infection and pests

3.Rational control of fertilizer and watering usage

Leaf surface temperature and humidity sensor Product Description:

This leaf surface temperature and humidity sensor is compact, stable, and highly sensitive, and is an important tool for studying leaf surface temperature and humidity, preventing infections, insect pests, and spray irrigation control. It accurately monitors trace water or ice crystal residues through changes in the dielectric constant of the leaf surface, and because it includes temperature detection, it can distinguish whether water or ice crystals are detected.

The appearance simulates the real leaf design, so it can more accurately reflect the real environmental conditions on the leaf surface. The product adopts RS485 output, the protocol can be customized, and can be extended with additional environmental monitoring elements such as atmospheric temperature and humidity, illuminance and so on.

Understanding Leaf Wetness Sensor:

A leaf wetness sensor typically utilizes a combination of electrical conductivity and temperature sensors to detect the presence of moisture on the leaf surface. These sensors are integrated into a durable and weather-resistant housing, allowing them to withstand outdoor conditions.

The leaf wetness sensor plays a vital role in modern agriculture and environmental monitoring. By providing real-time measurements of leaf moisture levels, this sensor enables farmers, researchers, and environmentalists to make informed decisions regarding disease management, irrigation optimization, environmental conservation, and crop productivity. Embracing this technology facilitates sustainable practices, reduces resource wastage, and promotes efficient agricultural systems capable of adapting to changing climatic conditions.
