Description:
The Soil NPK Sensor is designed to measure the levels of Nitrogen (N), Phosphorus (P), and Potassium (K) in soil. It helps in monitoring soil fertility and nutrient content, making it ideal for agriculture, smart farming, and STEM-based environmental projects.

Specifications:

  • Type: Soil Nutrient Sensor (NPK)
  • Measured Parameters: Nitrogen (N), Phosphorus (P), Potassium (K)
  • Measurement Method: Electrochemical / Ion-selective (varies by model)
  • Output Type: Digital (RS485 / Modbus) or Analog (model dependent)
  • Operating Voltage: 5V – 12V (varies by model)
  • Communication Protocol: RS485 (commonly)
  • Measurement Range:
    • Nitrogen: 0 – 1999 mg/kg
    • Phosphorus: 0 – 1999 mg/kg
    • Potassium: 0 – 1999 mg/kg
  • Accuracy: Moderate (field-level measurement)
  • Response Time: < 1 second
  • Probe Type: Stainless steel probes
  • Waterproof Rating: IP65 / IP68 (model dependent)

Features:

  • Measures three key soil nutrients simultaneously
  • Real-time monitoring
  • Durable and corrosion-resistant probes
  • Suitable for outdoor use
  • Easy integration with microcontrollers

Applications:

  • Smart agriculture
  • Soil testing and analysis
  • Precision farming
  • Greenhouse monitoring
  • Environmental studies

Pin Identification:

  • VCC → Power supply
  • GND → Ground
  • A → RS485 A
  • B → RS485 B

Important Note:

  • Requires RS485 to UART converter for microcontroller use
  • Calibration may be needed for accurate results
  • Avoid using in extremely dry or rocky soil
  • Clean probes after use to maintain accuracy

Package Includes:

  • 1 × Soil NPK Sensor Probe
