Combining a rugged soil moisture sensor with a pre-attached DataNode, the SD-DN-MO connects directly to the SDS two-wire path and continuously reports volumetric water content (VWC) back to the controller. Using 70 MHz frequency capacitance technology, the sensor is designed to provide stable moisture readings across different soil types while reducing the influence of salinity and soil texture. Moisture thresholds can be used to automatically skip or delay irrigation when soil moisture is already above a programmed setpoint, helping improve water efficiency and irrigation responsiveness.\u003c\/p\u003e\n\u003ch3\u003eSuitable Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCommercial landscape irrigation systems\u003c\/li\u003e\n\u003cli\u003eAgricultural and horticultural irrigation\u003c\/li\u003e\n\u003cli\u003eSports fields and turf irrigation systems\u003c\/li\u003e\n\u003cli\u003eParks and public landscape areas\u003c\/li\u003e\n\u003cli\u003eSoil moisture-based irrigation control\u003c\/li\u003e\n\u003cli\u003eRainfall-responsive irrigation management\u003c\/li\u003e\n\u003cli\u003eWater-efficient irrigation systems\u003c\/li\u003e\n\u003cli\u003eMulti-zone sites requiring program-specific moisture monitoring\u003c\/li\u003e\n\u003cli\u003eRemote moisture monitoring through SignalCloud™\u003c\/li\u003e\n\u003cli\u003eSDS two-wire irrigation systems requiring soil condition feedback\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSignal SD-DN-MO Two-Wire Moisture Sensor \u0026amp;
