CWT-LEAF-TH Leaf Surface Temperature and Humidity Sensor (RS485 type)

The temperature sensor consists of a high-accuracy thermistor and transmitter that can accurately measure temperature over the entire range. The humidity sensor is based on the dielectric constant measurement principle, simulates the shape of leaf, and simulates the surface of leaf realistically. Humidity can be accurately measured by changes in the dielectric constant of leaf surface. With good sensitivity, it can detect trace moisture residues on the leaf surface. The leaf temperature and humidity transmitter adopt waterproof design, low power consumption, and can be continuously monitored for a long time. Easy to install, it can be hung inside the greenhouse or on the branches of trees for long-term
uninterrupted monitoring. Widely used in greenhouses, laboratories, breeding, production environments, artificial climate chambers and other plant or body surface humidity measurement.

Features
1) Imitate the characteristics of leaf surface, and measure temperature and humidity quickly and accurately.
2) The denser vein pattern (15/cm) can detect smaller droplets and measure more sensitively.
3) The humidity measurement is sensitive and can accurately detect the leaf surface humidity.
4) High precision, fast response and good interchangeability.
5) Epoxy resin encapsulation, waterproof and moisture-proof, longer life.
