It is a professional-grade, 3-in-1 measurement device designed to operate flawlessly in both traditional soil and high-bulk EC soilless substrates. Hardware and Precision Measurement - Each Sensor Node utilizes robust stainless steel spikes to continuously measure the Volumetric Water Content (VWC) and Electrical Conductivity (EC) of the growing medium. Furthermore, an embedded precision temperature sensor is built directly into the probe to accurately track root zone temperatures, ensuring cultivators have verified data for plant health and crop steering. Daisy-Chain Connectivity and Scalability - To combat the limitations of single-sensor readings—which can be skewed by localized \"hot spots\" or water channeling—the Sensor Node is designed for an advanced multi-node architecture. Growers can physically daisy-chain up to four individual Sensor Nodes together. By using multiple nodes, the system captures data across various points in the medium to calculate a highly reliable average.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eHCS-2, NFS-1, NFS-2, NFS-3, TCS-1, GCS-1\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePrecision Measurement\u003c\/li\u003e\n\u003cli\u003eData Aggregation\u003c\/li\u003e\n\u003cli\u003eAdvanced Daisy-Chain Connectivity\u003c\/li\u003e\n\u003cli\u003eDynamic Reading Intervals\u003c\/li\u003e\n\u003cli\u003eSimplified Calibration\u003c\/li\u003e\n\u003cli\u003eFeed on Demand\" Control\u003c\/li\u003e\n\u003cli\u003eAffordable Scalability \u0026amp; Free App Access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 x WN-9 Sensor Node\u003c\/li\u003e\n\u003cli\u003e1 x ECS-7 12' Daisy Chain Control Cable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInput Voltage - 12V 0.1A\u003c\/li\u003e\n\u003cli\u003eMax Input Current - 0.1A\u003c\/li\u003e\n\u003cli\u003eWater Content Range - 0~100%\u003c\/li\u003e\n\u003cli\u003eEC Range - 0~30 mS\/cm\u003c\/li\u003e\n\u003cli\u003eMeasurement Range - 32~122°F (0~50°C)\u003c\/li\u003e\n\u003cli\u003eOperating Temperature - 32~122°F (0~50°C)\u003c\/li\u003e\n\u003cli\u003eOperating Humidity - ≤90%RH\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTechnical documentation:\u003c\/strong\u003e \u003ca href=\"https:\/\/kb.trolmaster.com\/hubfs\/Official%20Publish%20Product%20Document\/TechSheet_Substrate_Sensor_Node_VWC_EC_\u0026amp;_Temp_WN-9_EN.pdf\" target=\"_blank\" rel=\"noopener\"\u003eView technical sheet\u003c\/a\u003e\u003c\/p\u003e","brand":"TrolMaster","offers":[{"title":"Default Title","offer_id":62813935960394,"sku":"WN-9","price":119.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1030\/5994\/7850\/files\/WN-9_01.webp?v=1794081926","url":"https:\/\/thegrowfellas.com\/products\/trolmaster-wn-9-soil-moisture-ec-and-temp-3-in-1-substrate-sensor-node","provider":"The Grow Fellas","version":"1.0","type":"link"}
