Soil moisture, temperature, salinity, and pH are four key indicators determining soil fertility and crop growth environments. Precise monitoring of these parameters is of great significance for agricultural production, ecological restoration, and environmental governance.
Soil moisture content directly determines the irrigation resources available to crops: excessively low levels cause drought stress, while excessively high levels lead to root hypoxia and diseases. Temperature changes affect microbial activity and nutrient conversion efficiency. Salinity concentration is related to soil compaction and crop salt tolerance, while pH values dominate soil chemical reactions and the availability of trace elements. The dynamic balance of these four factors forms the basic framework of soil health.
Traditional soil parameter monitoring relies on laboratory chemical analysis, suffering from issues such as long duration, complex procedures, and insufficient spatial representativeness. With the development of sensor technology, integrated Soil Moisture Temperature Salinity PH Testers have saved significant costs. This portable device uses a plug-in probe design to synchronously collect four types of data in real time. Its moisture sensor employs frequency domain reflectometry to accurately measure volumetric water content; the temperature probe uses a thermistor to achieve monitoring with 0.1℃ precision; the salinity module quantifies ion concentration through the electrical conductivity principle; and the pH sensor realizes real-time pH measurement via ion-sensitive electrodes.
The tester supports multi-point synchronous monitoring and can continuously record change curves of soil parameters. Its data output supports Bluetooth transmission and docking with cloud platforms for remote monitoring and big data analysis. The device is easy to operate: simply insert the probe into the soil to be tested, and accurate data can be obtained within seconds.
