Soil NPK Sensor for Agriculture, Solar Powered

Soil NPK sensor for agriculture is designed for accurate monitoring of soil nutrient levels, including nitrogen, phosphorus, and potassium (1-1999 mg/kg). It features an RS485 output interface for real-time data transmission and an IP68-rated waterproof housing for reliable outdoor use. The NPK sensor operates with solar power, offering sustainable and maintenance-free performance. Built with a 316 stainless steel probe and epoxy resin vacuum sealing, it provides excellent corrosion resistance, no electrolysis, and long-term stability, making it ideal for precision agriculture and smart farming systems.

Feature

• USB Data Upload: SUCH soil sensor supports data uploading via a 485-to-USB module for real-time monitoring through upper computer software.
• Plug-and-Play Quick Response: Simply insert the sensor into the soil to display data within seconds. Designed with integrated digital circuit technology and international testing standards for fast response and reliable operation.
• Epoxy Resin Vacuum Sealing: Uses imported 316 stainless steel probe and high-density epoxy resin vacuum sealing to prevent water ingress and ensure excellent airtight performance.
• Stainless Steel Probe, No Electrolysis: Features an isolated design that completely prevents electrolysis and enhances resistance to salt and alkali corrosion.
• Resin-Sealed Waterproof and Anti-Corrosion: Vacuum-sealed with epoxy resin to improve waterproofing and corrosion resistance, ensuring stronger sealing performance and long-term durability.

How to Use

Quick Measurement Method:

Select an appropriate measurement location and avoid rocks or hard objects. Dig the surface soil according to the required measurement depth, keeping the underlying soil loose. Firmly insert the sensor vertically into the soil. Avoid shaking or twisting during insertion. For more accurate results, take multiple measurements within a small area and calculate the average value.

Buried Measurement Method:

Dig a vertical hole with a diameter greater than 20 cm. Insert the sensor horizontally into the soil wall at the desired depth. Refill and compact the soil to ensure firm contact between the probe and soil. After the sensor stabilizes for a period, it can be used for continuous monitoring and recording over several days or months.
