RS485 MODBUS-RTU Soil NPK Measure Sensor for Efficient Agricultural (IP68, 5-30V)

The Soil Sensor is crafted to precisely measure nitrogen, phosphorus, and potassium levels, optimizing soil fertility and fostering optimal plant growth conditions. Sporting a wide voltage range of 5-30V, it outputs data via the dependable RS485 MODBUS-RTU protocol. Its compatibility with Arduino UNO and the TTL to RS485 expansion board ensures straightforward setup. With accurate nutrient measurement, it boosts soil health, improves plant growth, and enhances yield, proving itself an indispensable tool in efficient farming, greenhouse cultivation, and hydroponic systems.

Featuring a robust IP68 protection level, the sensor is vacuum-sealed with black flame-retardant epoxy resin. Its probe, made of 316 stainless steel, boasts rust-proof, waterproof, and anti-corrosion attributes. It’s resistant to salt-alkali corrosion and prolonged electrolysis, offering exceptional durability even in high salt content soils. Its compact design allows it to remain buried long-term without compromising performance across diverse soil types.

The Soil Sensor is extensively used in various soil environment detection scenarios, including agricultural irrigation, flower and vegetable cultivation, and grassland monitoring. It's a vital tool for rapid soil testing in plant cultivation, scientific experiments, and grain storage. Its reliability and versatility make it invaluable in modern agriculture and soil science research.

Note that nitrogen, phosphorus, and potassium sensor data is a reference, not a substitute for professional instruments. Nitrogen is crucial for plant growth, influencing proteins and photosynthesis. Phosphorus affects energy metabolism and plant reproduction, and potassium regulates osmotic pressure and nutrient absorption. Each nutrient affects different plant growth aspects, making their measurement vital for effective soil management.
