IMS300 series tubular moisture sensor is a multi-functional composite product in intelligent agriculture and intelligent water conservancy system, integrating soil temperature measurement, soil moisture measurement and soil salt measurement. The soil moisture is measured by measuring the dielectric constant of the soil layer, the soil temperature is measured by the temperature sensor, and the soil salt is measured by measuring the soil conductivity. Meanwhile, the salt removal measurement adopts the contact mode, and the soil moisture and temperature are both non-contact mode, which improves the adaptability and stability. The sensor transmits data through RS485, which has the characteristics of high precision, low power consumption, stability and reliability

ECO-SMT moisture sensor is based on dielectric theory and using frequency domain measurement technology (FDR), which is independently developed in China, and can accurately measure the volume moisture content of soil and other porous media. The sensor has stable performance and good consistency, and has been widely used in the Ministry of Agriculture, the Ministry of Water Resources, the Academy of Agricultural Sciences, Yucheng Station of the Chinese Academy of Sciences, the Chinese Academy of Forestry and many universities in China. After years of application verification in various industries, it has been highly recognized by users.

The Hydra Probe II is a new three-parameter soil sensor from Stevens. An upgrade of the original Hydra Probe soil three-parameter sensor, the Hydra Probe II soil sensor provides increased measurement accuracy and supports SDI-12 and RS-485 communication protocols, giving you more choices. Unlike other soil sensors, the Hydra Probe Ⅱ soil sensor combines a variety of measurement elements in one measurement to obtain soil moisture, conductivity, salinity and soil temperature data, saving you a lot of valuable time.

The 5TE can determine soil moisture content, conductivity, and temperature with an oscillating frequency of 70MHz. The water content is determined by measuring the dielectric constant of the soil. The thermistor at the base of the triforked probe measures the soil temperature, and the conductivity is measured by screws in the middle of the surface of two of the probes.
