Leaf Surface Temperature and Humidity Sensor
Leaf temperature and humidity sensors are devices designed for precise measurement of plant leaf surface moisture, capable of detecting trace moisture or residual ice crystals on foliage. By simulating leaf characteristics, these sensors accurately reflect changes in the plant environment, helping prevent fungal and bacterial diseases. Widely used in agriculture, greenhouse management, and meteorological monitoring, they facilitate real-time surveillance and the implementation of protective measures.
Introduction
The leaf temperature and humidity sensor precisely measures moisture on leaf surfaces and detects trace amounts of water or ice crystals remaining on leaves. When water vapor is present on leaf surfaces, leaves become susceptible to fungal and bacterial diseases. This sensor measures the presence and duration of leaf surface moisture, enabling researchers or growers to predict disease outbreaks and implement protective measures to safeguard plants or crops.
Featuring a leaf-mimicking structural design, it realistically simulates leaf characteristics to more accurately reflect the leaf surface environment. It detects the presence of moisture or ice crystals by monitoring changes in the dielectric constant of the leaf mediumâs upper surface. Its low-power design supports long-term continuous monitoring, and its easy installation allows it to be suspended from greenhouse structures or weather station masts.
