This soil moisture monitoring equipment is an online monitoring system based on the FDR (Frequency Domain Reflectometry) principle. It can measure soil profile temperature, humidity, and conductivity in real time with an accuracy of ±3%, covering a range of 0-100% humidity and 0-20000 μS/cm conductivity. The equipment supports GPRS and 4G wireless transmission and is suitable for agricultural scenarios such as smart greenhouses, orchards, and irrigation, helping farmers accurately grasp soil moisture conditions.
Farmland irrigation has long relied on manual experience and rough judgment, which makes it difficult to accurately match the actual water requirements of crops at different growth stages. The emergence of soil moisture monitoring equipment provides a quantifiable technical solution to this problem. This equipment uses built-in soil moisture and temperature sensors to measure the soil dielectric constant based on the FDR principle, thereby determining the soil volumetric water content. The equipment also integrates a conductivity sensor to simultaneously acquire soil salinity data, providing multi-dimensional reference data for irrigation and fertilization management.
In terms of technical specifications, the soil moisture monitoring equipment measures soil temperature from -30 to 70℃ with an accuracy of ±0.3℃; soil moisture ranges from 0 to 100%, with an accuracy of ±3% under loam conditions; and soil conductivity ranges from 0 to 20,000 μS/cm, with an accuracy of ±3% within the 0 to 10,000 μS/cm range. The equipment supports multi-layer monitoring, typically in 20cm layers, with a monitoring depth of up to 100cm, and can be customized to different numbers of layers according to actual needs.
From an application perspective, the soil moisture monitoring equipment has been widely deployed in smart greenhouses, smart orchards, and smart irrigation systems. Data collected by the equipment is uploaded to a cloud platform in real time via wireless methods such as GPRS, 4G, or Bluetooth. Farmers can remotely view changes in temperature, humidity, and conductivity of each soil layer using their mobile phones or computers. This real-time online monitoring method replaces traditional manual sampling and testing, significantly improving monitoring efficiency and data continuity. In terms of drought early warning, the system can combine meteorological data for analysis, providing support for drought relief decision-making. Some of the equipment also features solar power and IP68 protection rating, making it suitable for unattended field environments.
Overall, soil moisture monitoring equipment transforms soil parameters from vague, subjective judgments into precise, objective data, providing a more scientific basis for farmland management decisions. With the advancement of digital transformation in agriculture, this type of equipment is moving from demonstration applications to large-scale deployment, becoming an important component of modern agricultural production infrastructure.
