Applicable in agriculture, greenhouses, and soil research.
The DFRobot MODBUS-RTU RS485 Soil NPK Measure Sensor (IP68, 5-30V) is an advanced device engineered to deliver precise and rapid data on soil nitrogen, phosphorus, and potassium levels. This essential information facilitates the optimization of soil fertility, thereby creating an ideal environment for plant growth. The sensor operates within a wide voltage power supply range of 5-30V and outputs data via RS485 using the dependable MODBUS-RTU protocol, ensuring quick response times and stable, reliable output. It is compatible with Arduino UNO R3 and TTL to 485 expansion boards, allowing for the swift establishment of a testing environment.
The sensor is constructed with a high protection level of IP68 and is vacuum-sealed with black flame-retardant epoxy resin. The probe, made from 316 stainless steel, is rust-proof, waterproof, and anti-corrosive, withstanding salt-alkali corrosion and long-term electrolysis. Its compact size permits long-term burial in various soil types without compromising performance.
This soil sensor is extensively applicable in numerous soil environment detection scenarios, including agricultural irrigation, greenhouses, flower and vegetable cultivation, grasslands and pastures, rapid soil testing, plant cultivation, scientific experiments, and grain storage. Its versatility and reliability render it an invaluable tool in modern agriculture and soil science research.
Note: Nitrogen, phosphorus, and potassium sensor data can only be used as a reference and cannot be as accurate as professional instruments.
