Product Description
KQS-SM Soil Comprehensive Sensor
KQS-SM is a multi-functional soil sensor capable of monitoring up to 8 soil parameters including soil temperature, moisture (water content), pH value, electrical conductivity, salinity, nitrogen, phosphorus and potassium. It features high precision, fast response and stable output. Less affected by soil salinity, it is suitable for various soil types. It can be buried in soil for long-term use, resistant to electrolysis and corrosion, with vacuum potting and fully waterproof design. Widely used in scientific experiments, water-saving irrigation, greenhouse cultivation, horticulture, grassland monitoring, rapid soil testing, plant cultivation, wastewater treatment, and grain storage.
Key Features
- High measurement accuracy, fast response, good interchangeability
- Less affected by soil salinity, suitable for various soil types
- Electrodes made of specially treated stainless steel, strong impact resistance
- Fully sealed, acid and alkali resistant, can be buried in soil or submerged in water for long-term monitoring
- Modular design, selectable configuration, supports up to 8 soil parameters
Applications
- Scientific Experiments: Multi-parameter soil monitoring in soil science research
- Water-saving Irrigation: Soil parameter data for precision agriculture irrigation decisions
- Greenhouse Cultivation: Real-time soil parameter monitoring in greenhouse environments
- Flower and Vegetable Gardening: Soil condition monitoring in horticulture
- Grassland and Pasture: Soil moisture and nutrient monitoring in pasture areas
- Rapid Soil Testing: On-site quick soil parameter detection
- Plant Cultivation: Soil environment recording in plant growth research
- Wastewater Treatment: Related parameter detection in wastewater discharge
- Grain Storage: Moisture and temperature measurement of granular materials

Calculation Formulas (Analog Signal Output)
F: Soil volumetric water content (%); T: Soil temperature (℃); I: Output current (mA); V: Output voltage (V).
Note: Only soil temperature and moisture have analog signal output; other parameters do not.
| Signal Type | Moisture Formula | Temperature Formula |
|---|---|---|
| 4-20mA | F = (I - 4) / 16 * 60 | T = (I - 4) / 16 * 120 - 40 |
| 0-5V | F = V / 5 * 60 | T = V / 5 * 120 - 40 |
