Χαρακτηριστικά

The soil electrical conductivity (EC) and pH sensor operate within a wide voltage range of 5-30V, transmit data via RS485 using the MODBUS-RTU protocol, and deliver quick, reliable responses with minimal interference from environmental factors. The sensor is designed for easy integration with Arduino systems and is well-suited for hydroponic systems, saline and alkaline soil management, and drip irrigation systems.

The soil sensor boasts an IP68 protection level, vacuum-filled and sealed with black flame-retardant epoxy resin. The probe, crafted from 316 stainless steel, offers rust-proof, waterproof, anti-corrosion, salt-alkali corrosion resistance, and long-term electrolysis resistance properties. Its performance is influenced by the soil salt content. Compact in size, it can be buried in the soil for extended periods and is compatible with various soil types.

The soil sensor features an automatic temperature compensation function for conductivity, ensuring measurement accuracy regardless of environmental changes. Its applications span across agricultural irrigation, greenhouses, floriculture and vegetable farming, grassland pastures, rapid soil testing, plant cultivation, scientific experiments, grain storage, and other soil environment testing scenarios.

Soil electrical conductivity (EC) represents the salinity level in the soil. These parameters serve as crucial indicators of soil fertility and health, with a direct impact on plant life. High salt content in soil impedes water absorption by plants, despite high soil moisture content. This condition could eventually “burn” the plant. Optimal plant growth occurs within preferred environmental conditions, including specific ranges of soil moisture, temperature, and EC levels. Data on these parameters is essential for growers to understand necessary actions for ensuring plant health and achieving higher yields.

Soil pH, also referred to as “soil reaction”, is an acid-base reaction of the soil solution. It primarily depends on the concentration of hydrogen ions in the soil solution, expressed by the pH value. A solution with a pH value of 7 is neutral; a solution with a pH value less than 7 exhibits an acidic reaction; a solution with a pH value greater than 7 shows an alkaline reaction. Soil pH can generally be categorized into the following levels:

Soil acidity and alkalinity, pH values:

<4.5 Extremely acidic
4.5–5.5 Strongly acidic
5.5–6.5 Acidic
6.5–7.5 Neutral
7.5–8.5 Alkaline
8.5–9.5 Strongly alkaline
>9.5 Extremely alkaline
