What is a leaf temperature and humidity sensor?
In agricultural production, the temperature and humidity related to plant growth mainly include soil temperature and humidity, air temperature and humidity, leaf temperature and humidity. In the past, people have studied soil temperature and humidity, air temperature and humidity, but they have ignored them. The temperature and humidity of the leaf surface.

Plant leaf surface temperature and humidity are environmental factors that are closer to plant physiology, and its temperature and humidity have an important impact on the infection of pathogens on the surface of plant leaves. The types and numbers of air pollutants retained and adsorbed on the leaf surface of different temperature and humidity are also different. These pollutants settle on the surface of the plant leaf and interact with the leaf surface, which is easy to change the leaf surface humidity. When the plant leaf surface temperature and humidity are too high, it will increase the breeding probability of field pathogens and increase the risk of leaf infection. Once plants are infected with pathogens, the pathogens will damage the leaf surface structure, which is not conducive to the growth and development of plants. It can be seen that the monitoring of leaf temperature and humidity is essential in agricultural production.

In order to prevent plant diseases caused by changes in leaf surface temperature and humidity in time, we independently developed a leaf surface temperature and humidity sensor (model: RS-WS-N01-YM-1), which is mainly used to monitor leaf surface Temperature and humidity, and can monitor the trace moisture of the leaf surface. It can help managers to accurately know the temperature and humidity of plants and provide important reference for timely prevention and control of plant diseases.

The leaf surface temperature and humidity sensor is composed of a high-precision thermistor and a humidity sensor, which can accurately measure the temperature and humidity in the entire range. It has the advantages of fast response speed, high measurement accuracy, strong anti-interference ability and stable performance. Using standard MODBUS-RTU communication protocol, RS485 signal output, the communication distance can reach 2000 meters. Beautiful appearance, small size, easy to install, widely used in greenhouses, laboratories, breeding, production environments, artificial climate rooms and other plants or object surface humidity measurement.

What are the advantages of leaf temperature and humidity sensors?

1. Leaf-like design

Situation. Accurate measurement of humidity by imitating the change in the dielectric constant of the blade surface.

2. High accuracy

The sensor has a built-in high-precision low-power chip, its humidity monitoring range is 0-100%RH, and its accuracy is ±5%RH (@25℃); temperature monitoring range is -40~ 80°C, accuracy ±0.5°C (@25°C).

3. High sensitivity

This sensor imitates leaf media and chooses denser leaf vein patterns (15 lines/cm), and has a strong ability to perceive changes in external temperature and humidity, and can detect smaller droplets.

4. Thermal grease design

In order to protect the thermistor from the external environment, the thermistor in the leaf temperature and humidity sensor is specially coated with thermal grease. The thermal grease has excellent electrical properties. Insulation, excellent thermal conductivity, low freeness (towards zero), high and low temperature resistance, water resistance, ozone resistance, weathering resistance, and does not affect temperature monitoring.

5. Waterproof grade IP67

The leaf surface temperature and humidity sensor shell is made of epoxy resin encapsulated for waterproof and moisture-proof, with a waterproof grade of IP67, which has a longer life span and can be directly used outdoors.

6. Simple installation

The installation of the leaf temperature and humidity sensor is simple. You only need to place the sensor next to crops or leaves, and use a non-metallic wire to pass through the small hole in the front of the leaf sensor and hang it on the tree through a wire. Use wire or thread to fix the equipment on the branches or stems on the branches, and the installation is complete.

7. Free cloud platform

The leaf temperature and humidity sensor can upload the collected data to the environmental monitoring cloud platform by connecting to a small host, network data collector, etc. The cloud platform can read, manage, and query the collected data, making it convenient for users to remotely query and manage data. When the leaf surface temperature and humidity exceed the limit set by the manager, the platform will notify the manager by phone, text message, email, etc., so that the manager can take relevant control measures on the plant in time.

Nowadays, with the rapid development of facility agriculture, the promotion and use of foliar temperature and humidity sensors are also increasing. The application of foliar temperature and humidity sensors can not only help managers understand the growth and development of crops, and improve control The effect can also effectively avoid production loss and ensure the healthy growth of plants.



is emerging as one of the most popular sensor solution, moving beyond its OEM sensor benefits, with conclusive scientific evidence suggesting the positive role play in environmental monitoring systems.
