VMS-3002-TR-NPK-N01 Soil NPK Sensor

VMS-3002-TR-NPK-N01 Soil NPK Sensor

Soil Nitrogen (N), Phosphorus (P), Potassium (K) Detection Sensor

The VMS-3002-TR-NPK-N01 Soil NPK Sensor is an advanced soil nutrient measurement sensor designed to detect and analyze the three primary soil nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K). These nutrients are essential for plant growth, and accurate measurement helps optimize fertilizer usage and improve crop yield.

This sensor is widely used in smart agriculture, precision farming, greenhouse monitoring, and IoT-based soil analysis systems.

Key Features

• Measures Soil NPK Nutrient Levels

• Detects Nitrogen (N), Phosphorus (P), and Potassium (K)

• High Accuracy & Stable Performance

• Fast Response Time

• Durable Stainless Steel Probes

• Long Cable for Flexible Installation

• Suitable for Field and Greenhouse Use

Working Principle

The sensor uses electrochemical sensing technology:

1. The metal probes are inserted into the soil.

2. Soil nutrients affect the electrical properties around the probes.

3. Internal signal processing converts these changes into nutrient concentration data.

4. Output data can be read by a controller or monitoring system to determine soil fertility.

This allows farmers and researchers to make data-driven fertilizer decisions.
