The DFRobot MODBUS-RTU RS485 Soil Moisture, Temperature & EC Sensor (IP68, 5-30V) facilitates the rapid acquisition of soil temperature, moisture, and electrical conductivity (EC) data, ensuring precise irrigation for optimal plant growth. It supports a wide voltage power supply range and communicates data via RS485 using the reliable MODBUS-RTU protocol. The sensor exhibits quick response times and delivers stable, reliable output, making it suitable for integration with an Arduino UNO R3 and a TTL to RS485 expansion board to efficiently create a test environment.
The sensor is designed with a protection level of IP68 and is vacuum-filled and sealed with black flame-retardant epoxy resin. The probe material is made of 316 stainless steel, which is rust-proof, waterproof, and resistant to corrosion, including salt-alkali corrosion and long-term electrolysis. It is small, can be buried in the soil for extended periods, and is suitable for various soil types. The sensor also features an automatic temperature compensation function for conductivity, ensuring measurement accuracy regardless of environmental changes.
This sensor is widely used in agricultural irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant culture, scientific experiments, grain storage, and the measurement of moisture content and temperature of various particulate matter. Proper soil temperature promotes plant root growth and nutrient absorption, while appropriate soil moisture helps plant roots absorb water and nutrients, maintaining water balance within plant cells. Soil electrical conductivity (EC) indicates soil salinity, which affects plant water absorption and overall health. Understanding these parameters is crucial for ensuring plant health and achieving higher yields.
Note: Ensure proper handling to avoid damage to the sensor and maintain its accuracy.
