soil moisture monitoring station is designed to measure soil moisture content, temperature, and electrical conductivity; it supports wired, GPRS, and Bluetooth transmission modes and features a "zero-configuration" design that allows for rapid deployment in the field.
soil moisture monitoring station is an automated monitoring device that integrates data acquisition, storage, and remote transmission capabilities. Its primary function is to measure soil volumetric water content and temperature values. The device monitors real-time changes in soil dielectric permittivity via sensor probes embedded in the soil, utilizing the principles of Frequency Domain Reflectometry (FDR) or Time Domain Reflectometry (TDR) to calculate soil moisture content. The sensors feature a stainless steel probe structure, allowing them to remain embedded in the soil for extended periods without significant corrosion; this enables continuous data acquisition regarding moisture fluctuations at various soil depths throughout the crop growing season.
In terms of data transmission, soil moisture monitoring station supports three distinct modes: wired, GPRS, and Bluetooth. Wired transmission is ideal for centralized data acquisition scenarios within a control room, allowing for direct connection to PLC or DCS systems via an RS485 interface for real-time data retrieval. GPRS transmission is suited for unattended field environments, where data is periodically uploaded wirelessly to a cloud-based management platform, enabling users to remotely view real-time data and historical records via a computer or mobile device. Bluetooth transmission is primarily intended for rapid on-site commissioning and data downloading, allowing maintenance personnel to connect directly to the device via a smartphone or tablet to retrieve sensor readings without the need to carry additional cables or laptop computers. This combination of three transmission modes comprehensively addresses data acquisition requirements across the entire spectrum—from indoor environments to the field, and from remote monitoring to on-site operations.
soil moisture monitoring station features a "zero-configuration" design; once unboxed, the device automatically begins operation immediately after the sensors are deployed and the power supply is connected, requiring no complex parameter configuration. The unit features a compact structure, allowing a single person to complete the on-site installation within 30 minutes. The device is equipped with a power system comprising a solar panel and an internal lithium battery, ensuring continued normal operation for several days even during prolonged periods of overcast or rainy weather, thereby guaranteeing the reliability of long-term, unattended field monitoring.
soil moisture monitoring station is capable of simultaneously collecting data on three parameters—soil moisture, temperature, and electrical conductivity—and can be expanded to incorporate additional sensor modules (such as soil pH, air temperature and humidity, solar radiation, and rainfall) to meet specific user requirements. The soil moisture measurement range is 0–100%, with a measurement accuracy of ±3%. The soil temperature measurement range is -30 to 70°C, with a measurement accuracy of ±0.3°C. The soil electrical conductivity measurement range is 0–20,000 µS/cm, with an accuracy of ±3% within the 0–10,000 µS/cm range. The device features built-in storage capacity for no fewer than 500,000 data records, supporting both local querying and exporting of historical data. In the agricultural sector, the real-time soil moisture data provided by the monitoring station serves to guide precision irrigation and water conservation management. In the fields of water conservancy and hydrology, the station's data is utilized for analyzing soil moisture trends and issuing drought warnings. In the realm of geological hazard early warning, anomalous fluctuations in soil saturation levels provide a critical reference basis for assessing landslide risks.
