Foliar temperature and humidity sensor for plant ecological information monitoring

Product introduction：

The leaf temperature and humidity 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.

Plant leaf surface volume water content is not only a physiological characteristic of the plant, its content also usually has an important impact on leaf infection with pathogens, for example, during the infection of pathogens, if the leaf surface is completely wetted is conducive to disease infestation.

Once infested, the leaf surface structure is damaged and the influence of wetting properties on the retention of pesticide droplets for pest control needs to be considered.

Thus, the measurement of the foliar moisture sensor allows ecologists to clearly guide the current state of the crop and determine whether it is at risk of disease infection.

The NiuBoL Foliar Moisture Sensor is specialized in testing the volumetric water content of plant leaf surfaces. The sensor of this device simulates the shape of a leaf surface with a width-sensitive electronic induction coil, which can test the humidity of plant leaf surfaces with high precision and is widely used in agricultural production and agricultural research to study the growth and development of crops, pest and disease control.
