Leaf Temperature Humidity Sensor Leaf Moisture Recorder For Smart Agriculture

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.

With stable performance and high sensitivity, the foliar humidity sensor is an important tool for observing and studying foliar humidity, preventing pests and diseases, as well as spraying and sprinkler control.

The niubol foliar temperature and humidity sensor is a composite sensor that can accurately measure both foliar temperature and foliar humidity.

The temperature sensor is composed of a high precision NTC thermistor and transmitter. The transmitter is equipped with offset compensation and temperature calibration, allowing accurate temperature measurement over the entire range.

The humidity sensor, on the other hand, is based on the principle of dielectric constant measurement, and realistically simulates the leaf surface characteristics by imitating the shape of the leaf.

It can accurately measure the amount of water or ice present by the change of dielectric constant on the leaf surface. It has good sensitivity and can detect trace amount of water or ice crystal residue on the leaf surface.

The overall waterproof design of the leaf surface temperature and humidity sensor allows for long-term uninterrupted monitoring with low power consumption. It is easy to install and can be hung on the greenhouse shed or mounted on the mast of a weather station.
