Portable Soil Moisture Measuring Instrument - A portable soil moisture measuring instrument that empowers scientific decision-making. Recommended model JC-GTS3- Shandong Jiucheng Intelligent Technology, providing high-quality equipment and one-stop service solutions, highly praised and recognized by users. It stably transmits data, empowers scientific decision-making, and demonstrates the unique advantages of the 485 Modbus RTU protocol. In winter, agricultural production areas are mostly in outdoor environments, and harsh conditions such as low temperatures and strong winds can easily cause communication interruptions, affecting the timeliness and reliability of monitoring data. The 485 Modbus RTU protocol has strong anti-interference ability and long-distance transmission characteristics, which can achieve stable data transmission in complex environments and ensure uninterrupted monitoring work. At the same time, the protocol supports multi device networking, which can achieve full coverage monitoring of soil moisture in large areas of farmland and form a dynamic database of regional soil moisture. The agricultural technology department can accurately predict the risks of drought and freezing damage and develop targeted management plans by combining monitoring data with meteorological forecasts. In the northern winter wheat region, based on monitoring data, the winter water irrigation time can be optimized to avoid low temperature periods; In the hilly areas of the south, timely guidance can be given to farmers to open ditches and disperse soil moisture, avoiding root rot caused by excessive soil moisture, and shifting winter agricultural management from "experience based" to "data based".

3、 Advantages and Characteristics

A single soil tube sensor can simultaneously measure soil parameters at multiple depths, and the monitoring depth can be customized (less than 1M).

The sensor adopts a low-power design, with a power consumption as low as 0.26W, suitable for long-term unmanned monitoring in the field.

Each layer of the sensor can independently measure temperature, humidity, and conductivity parameters.

The sensor housing is made of imported PC material, which has high strength, corrosion resistance, and no pollution to the environment.

The waterproof level of the sensor reaches IP67, which is suitable for long-term outdoor monitoring.

The sensor measures the average humidity within a certain area, which compensates for the limitations of single point measurement.

The sensor adopts a self-designed spiral measuring electrode to improve the contact between the sensor and the soil, and to avoid measurement errors caused by air gaps as much as possible.
