The 8-in-1 Integrated Soil Sensor is a multi-parameter sensor that combines temperature and humidity, conductivity, salinity, NPK and PH. By measuring the dielectric constant of soil, it can directly and stably reflect the real moisture content of various soils. It is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grass pastures, soil quick test, plant cultivation, sewage treatment, fine agriculture and other occasions. The 8-in-1 Integrated Soil Sensor is a multi-parameter soil testing device that integrates a variety of soil parameter measurement functions in a small device, usually including: 1. Temperature: Measures the temperature of the soil, which is important for understanding the soil ecosystem and crop growth. 2. Moisture: Measures the moisture content of the soil, which is critical for irrigation management and understanding the moisture status of the soil. 3. Conductivity: Measures the concentration of electrolytes in the soil, which can reflect the soil's salt levels and nutrient content. 4. Salinity: Detects the salt content of the soil, which is particularly important for agriculture in coastal areas or saline soils. 5. NPK (Nitrogen, Phosphorus, Potassium): Measurement of the content of major nutrients such as Nitrogen, Phosphorus, Potassium, etc. in the soil, which is the key to judge the level of soil fertility and to decide on fertilisation strategies. 6. PH (pH): Detects the acidity and alkalinity of the soil, which directly affects nutrient uptake by plants and crop growth. Such a sensor is ideally suited for agriculture, horticulture, environmental monitoring, and soil science research. Uses for the 8-in-1 integrated soil sensor include: - Precision agriculture: to help farmers understand soil conditions and achieve precise irrigation and fertiliser application to improve crop yield and quality. - Environmental protection: monitor changes in the soil environment and detect and deal with soil pollution in a timely manner. - Scientific research: Provide accurate soil parameter data for soil science, ecology and other research fields. - Education popularisation: in schools or public education occasions, used for teaching demonstration, let children understand the importance of soil and scientific knowledge. The advantage of the 8-in-1 soil sensor lies in its versatility and portability, which allows users to quickly and easily obtain comprehensive information about the soil so that they can make more rational management and planting decisions. 8 in1 Integrated soil sensor parameters Supply Voltage DC 5-24V Power Consumption 15mA@12V DC Communication method RS485 Baud rate 9600bps Range and Accuracy Temperature range: -40-80°C Temperature accuracy: ±0.5°C Moisture range: 0%-100%RH Moisture accuracy: ±3% Conductivity range: 0-10000us/cm Conductivity Accuracy: ±10% NPK range: 0-2000mg/Kg Accuracy of NPK: ±2% PH range: 3-10pH PH precision: ±0.6pH Salt range: 0-5500mg/L Salt accuracy: ±10% Working Environment: -40~80℃ Sealing material: Black epoxy resin Material: Five-pin design, probe material for the solid stainless steel three, hollow stainless steel one, zinc alloy one, the sensor total length 138 ± 1mm, width 45mm ± 1mm, thickness 15 ± 1mm, sensor probe length 65mm ± 1mm, diameter 3 ± 0.2mm
