Portable USB Type-C 8-in-1 Soil Multi-Parameter Monitor Measurement Parameters and Technical Specifications

Role and Value of Core Measurement Parameters in the 8-in-1 Soil Multi-Parameter Monitor

Soil Temperature
Soil temperature directly affects seed germination, root growth, and microbial activity. Accurate monitoring helps determine sowing time, fertilization windows, and irrigation strategies.

Soil Moisture
Soil moisture is the core indicator for water-saving irrigation and precision agriculture. Real-time monitoring of soil water content avoids over-irrigation or water deficiency, improving water resource utilization efficiency.

Soil EC (Electrical Conductivity)
EC reflects the overall concentration of soluble salt ions in soil, an important parameter for assessing soil fertility, salinization degree, and fertilization rationality.

Soil Salinity
High salinity inhibits plant water uptake, restricting crop growth. Salinity monitoring is particularly critical for protected agriculture, greenhouses, and coastal areas.

Soil Available Nitrogen (Alkali-Hydrolyzable Nitrogen)
Available nitrogen is an important form of short-term absorbable nitrogen for plants, directly influencing leaf growth and yield levels.

Soil Available Phosphorus (Effective Phosphorus)
Effective phosphorus relates to root development, flowering and fruiting, and energy metabolism—an important indicator for high-value crop management.

Soil Available Potassium (Effective Potassium)
Available potassium helps improve crop stress resistance and promotes sugar transport, significantly impacting fruit and vegetable quality.

Soil pH Value
pH determines nutrient availability and microbial activity, serving as the fundamental parameter for judging soil suitability for specific crops.

Measurement Principles of the Soil Sensor

FDR (Frequency Domain Reflectometry) Principle
This product uses FDR technology to measure soil moisture and electrical properties. By analyzing the soil's response to high-frequency electromagnetic signals, it calculates changes in dielectric constant, providing stable, highly repeatable measurement results suitable for rapid field testing.

Soil NPK Measurement Explanation
Soil available nitrogen, phosphorus, and potassium parameters are based on comprehensive analysis of soil conductivity. The sensor calculates theoretical NPK values through EC combined with empirical models.
Due to variations in soil types and environments, these values are used for trend analysis and management decision reference, not equivalent to laboratory chemical analysis results.

Soil pH Electrode Method
Soil pH is measured using the electrode method. After inserting the probe into the soil, the electrode reacts with hydrogen ions in the soil, generating a potential difference proportional to hydrogen ion concentration, thereby calculating soil acidity and alkalinity.

FAQ:

Q1: Is an external power supply required?
A: No, the sensor is powered by the phone.

Q2: Does it support data export?
A: Yes, supports exporting to Excel files for later analysis and archiving.

Q3: Are NPK values equivalent to laboratory testing?
A: No. NPK values are empirical reference values based on EC, suitable for trend judgment and management decisions.

Q4: Is there a depth requirement when inserting the sensor into the soil?
A: To ensure measurement stability and consistency, it is recommended to fully insert the probe so the metal probes fully contact the soil. For different application scenarios, multi-point and multi-depth measurements can be performed based on crop root depth to obtain more representative data.

Q5: Can data from different soil types be directly compared?
A: It can be used for trend and relative change analysis, but absolute values from different soil types (e.g., sandy, loamy, clay) should not be directly compared as a uniform standard. Different soil physical structures and ion compositions affect EC, salinity, and NPK calculation results. Long-term monitoring and comparison combined with local soil conditions are recommended.

Q6: Does the device require regular calibration or maintenance?
A: The sensor is factory-calibrated and does not require frequent calibration under normal use. To maintain long-term measurement accuracy, it is recommended to clean the probe surface of attachments (such as biofilms, silt) after use in high-salt or highly corrosive environments, and avoid strong impact or bending to extend service life.

Summary

The NiuBoL USB Type-C Output Portable 8 IN 1 Integrated Soil Moisture Sensor combines multi-parameter soil testing, direct phone connection, free APP, and industrial-grade structural design, solving the problems of traditional soil testing equipment being bulky, expensive, and complex to operate.

For users needing rapid soil information access, improved management efficiency, and lowered testing barriers, this is a practical, reliable, and long-term value soil monitoring tool.
