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.\n\nThe 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.\n\nKey Features\n\n\nThree-in-One Sensing – Measures soil temperature, moisture, and electrical conductivity simultaneously\n\nRS485 MODBUS-RTU Output – Compatible with Arduino (via TTL-to-RS485 adapter), Raspberry Pi, PLCs, and data loggers\n\nWide Voltage Range – Operates on 5–30 V DC power supply\n\nIP68 Rated – Vacuum-filled and sealed with black flame-retardant epoxy resin for long-term burial\n\n316 Stainless Steel Probe – Rust-proof, waterproof, and resistant to corrosion and electrolysis\n\nAutomatic Temperature Compensation – Ensures accurate EC measurements across 0–50°C range\n\nCompact Design – 123 × 45 × 15 mm with 2 m cable length\n\n\nSpecifications\n\n\nPower Supply – DC 5–30 V (0.7 W @ 24 V)\n\nOutput – RS485 (MODBUS-RTU)\n\nMoisture Range – 0–100% (resolution: 0.1%, accuracy: ±2% at 0–50%, ±3% at 50–100%)\n\nTemperature Range – −40°C to +80°C (resolution: 0.1°C, accuracy: ±0.5°C)\n\nEC Range – 0–20,000 µS/cm (resolution: 1 µS/cm, accuracy: ±3% FS up to 10,000 µS/cm, ±5% FS above)\n\nWorking Temperature – −40°C to +60°C\n\nProtection – IP68\n\nCable Length – 2 m\n\nDimensions – 123 × 45 × 15 mm\n\n\nIdeal For\n\nPrecision agriculture and smart farming\nGreenhouse climate and irrigation management\nEnvironmental and soil research\nGrassland and pasture monitoring\nGrain storage moisture monitoring\n\n\nPackage Contents\n\n1× RS485 Soil Sensor (temperature, humidity, and EC)\n\n\nResources\n\nDFRobot Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":536,"title":"Default Title","sku":"DF-SEN0601","mpn":"SEN0601","price":73.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":203,"option1":"Default Title"}]}
