SOIL MOISTURE SENSOR

SKU: SMT

SMT is a soil moisture, soil temperature and soil EC. Utilize advanced technology, Frequency Domain Reflectometry to deliver high accuracy and stable measurement of Soil Moisture, not affected by Fertilizer contents and Temperature like the simple Capacitance Moisture Sensor on the marker. Sensor output is RS485 / modbusRTU easily connected to any control and monitoring system. Typical applications are: intelligent irrigation systems, greenhouses, soil condition check ...

Pre-calibrated

  • Sensors are pre-calibrated at factory to deliver high accuracy and quick installation
