Leaf Humidity And Temperature Sensor
Video
Product Details
Features
● Imitating leaf surface characteristics, temperature and humidity measurement is fast and accurate.
●It has high precision temperature correction function and can output temperature signal independently.
●The humidity measurement is sensitive and can accurately detect the moisture or ice crystal residue on the leaf surface.
●Analog voltage/current can be selected, and RS485 signal can be output.
●It is encapsulated with ABS and epoxy resin, which is waterproof and moisture-proof and has a longer service life.
● It can integrated all kinds wireless module including the GPRS, 4G., WIFI, LORA, LORAWAN
● We can custom made the matched cloud server and software,and real-time data can be viewed on the computer in real time
Principle
The humidity sensor is based on the principle of dielectric constant measurement, and simulates the leaf features by imitating the shape of blades. It can accurately measure the amount of water or ice by changing the dielectric constant of leaf surface. The sensitivity is good, and trace moisture or ice crystal residues on the leaf surface can be detected.
Product Application
This product can be widely used in environment, greenhouse, laboratory, breeding, warehousing, construction, high-grade buildings, industrial plants and other environmental temperature and humidity measurement of plant surface.
