NPK Soil Sensor

The NPK Soil Sensor is a rugged, probe-type sensor designed to measure soil nutrient content—Nitrogen (N), Phosphorus (P), and Potassium (K)—directly in the field. It’s ideal for precision agriculture, greenhouse automation, and soil research, delivering stable, real-time readings for smarter fertilization decisions.

Technical Specifications:

• Measured parameters: Nitrogen (N), Phosphorus (P), Potassium (K)
• Power supply: DC 9–24 V
• Output options:
• Analog 0–5 V / 0–10 V
• 4–20 mA (industrial standard)
• RS485 (Modbus RTU)
• Probe type: Stainless steel insertion probes
• Housing: Waterproof, field-ready enclosure
• Operating environment: Soil / agriculture applications

Features:

• Direct in-soil measurement (no chemical reagents required)
• Multiple output formats for PLC, MCU, and data logger compatibility
• Strong corrosion resistance for long-term deployment
• Quick response and stable readings in varying soil conditions

Applications:

• Smart farming & fertigation systems
• Greenhouses and hydroponics monitoring
• Soil nutrient mapping & research
• Automated irrigation controllers
