## Description

The RS485 Soil Sensor provides real-time monitoring of soil temperature, moisture, and electrical conductivity (EC) in a single rugged probe. It communicates via the MODBUS-RTU protocol over RS485, making it easy to integrate with Arduino, Raspberry Pi, and automated irrigation or climate control systems. The probe is constructed from 316 stainless steel and sealed with flame-retardant epoxy resin to IP68 standards, allowing long-term burial in soil or submersion in water. Built-in automatic temperature compensation ensures accurate EC readings regardless of environmental changes. Key Features Three-in-One Sensing – Measures soil temperature, moisture, and electrical conductivity simultaneously RS485 MODBUS-RTU Output – Compatible with Arduino (via TTL-to-RS485 adapter), Raspberry Pi, PLCs, and data loggers Wide Voltage Range – Operates on 5–30 V DC power supply IP68 Rated – Vacuum-filled and sealed with black flame-retardant epoxy resin for long-term burial 316 Stainless Steel Probe – Rust-proof, waterproof, and resistant to corrosion and electrolysis Automatic Temperature Compensation – Ensures accurate EC measurements across 0–50°C range Compact Design – 123 × 45 × 15 mm with 2 m cable length Specifications Power Supply – DC 5–30 V (0.7 W @ 24 V) Output – RS485 (MODBUS-RTU) Moisture Range – 0–100% (resolution: 0.1%, accuracy: ±2% at 0–50%, ±3% at 50–100%) Temperature Range – −40°C to +80°C (resolution: 0.1°C, accuracy: ±0.5°C) EC Range – 0–20,000 µS/cm (resolution: 1 µS/cm, accuracy: ±3% FS up to 10,000 µS/cm, ±5% FS above) Working Temperature – −40°C to +60°C Protection – IP68 Cable Length – 2 m Dimensions – 123 × 45 × 15 mm Ideal For Precision agriculture and smart farming Greenhouse climate and irrigation management Environmental and soil research Grassland and pasture monitoring Grain storage moisture monitoring Package Contents 1× RS485 Soil Sensor (temperature, humidity, and EC) Resources DFRobot Wiki
