Soil NPK Sensor For Arduino/ Raspberry Pi RS485-JXBS-3001 with MAX485 Module

The RS485-JXBS-3001 Soil NPK Sensor is an industrial-grade solution designed for precision agriculture and environmental monitoring. This high-quality sensor provides real-time data for Nitrogen (N), Phosphorus (P), and Potassium (K) levels in the soil. Engineered with high-stability sensing technology, it allows for deep soil penetration and quick data acquisition, making it essential for optimizing crop yields and fertilizer usage.

Industrial Reliability & Precision

Built to withstand harsh environments, the sensor features an IP68 waterproof rating and is constructed with high-quality stainless steel probes. It uses the RS485 Modbus RTU protocol, allowing for long-distance data transmission and the ability to daisy-chain multiple sensors on a single bus.

Ready for MCU Integration

To make development easier for makers and researchers, this sensor comes bundled with a MAX485 TTL-to-RS485 module. This allows you to interface the industrial RS485 signal directly with 5V or 3.3V microcontrollers like Arduino, ESP32, or Raspberry Pi.

Key Features

• High Sensitivity: Accurate detection of N, P, and K ions with a resolution of 1mg/kg.

• Durable Construction: Fully sealed with black flame-retardant epoxy resin; IP68 rated for permanent burial.

• Wide Voltage Input: Operates reliably between 12V and 24V DC.

• Low Power Consumption: Optimized for battery-powered or solar-powered IoT nodes.

• Corrosion Resistant: Special alloy probes designed to resist electrolysis and soil acidity.

Technical Specifications

Typical Application Scenarios

• Smart Greenhouses: Automated nutrient dosing based on real-time soil data.

• Precision Farming: Large-scale crop monitoring using LoRaWAN or Wi-Fi gateways.

• Hydroponics: Monitoring nutrient concentration in various growth mediums.

• Research & Academics: PhD-level studies in soil science and smart agriculture.

Note

Wiring Tip: Ensure the power supply is at least 12V for the sensor to operate correctly; the 5V output from an Arduino is insufficient to power the sensor itself, though it can power the MAX485 module. Cross-check your Modbus IDs and Baud rates if you encounter communication errors.
