The WCS-9 replaces that guesswork with real-time readings of \u003cstrong\u003evolumetric water content, EC and temperature\u003c\/strong\u003e from the root zone. The set includes a sensor display, one WN-9 sensor node, a 16 ft RJ12 cable set and a T-splitter. Each display takes up to \u003cstrong\u003efour nodes\u003c\/strong\u003e on a daisy chain and reports both the individual readings and their average. Averaging matters because a single probe can be fooled by a hot spot or water channeling in one block. Water content reads from 0 to 100%, and EC from 0 to 30 mS\/cm. The node is pre-calibrated for rockwool, and other media only need a single saturated-point calibration. It works in both traditional soil and high bulk-EC soilless substrates. Readings also show in the free TM+ Pro app, with history graphs and high or low alarms. The package measures 5.43 × 6.69 × 2.52 in and weighs 1.39 lbs.\u003c\/p\u003e\u003ch2\u003eSetting Up the TrolMaster WCS-9 for Crop Steering\u003c\/h2\u003e\u003cp style=\"text-align: justify;\"\u003eUpdate the controller firmware first, since older versions do not recognize the WCS-9. On Aqua-X controllers, plug the display into the Medium port. On Hydro-X Pro, Tent-X and Green-X, it goes into the Sensors port instead. Press the addressing button on the display to link it, then shake each node to pair it. Normal readings refresh every minute, and the display button forces an immediate update. During a Feed on Demand event the refresh drops to every 10 seconds. Feed on Demand lets you set different moisture targets for morning, noon and evening. Max On Time and Dry Back time settings shape each irrigation shot for precise dry-backs. Aqua-X Pro and Hydro-X Pro support up to 50 displays, Aqua-X Plus up to 20, and the others one each. Owners of older WCS-2 or WCS-3 sensors can check TrolMaster's WCS-9 upgrade program for an exchange.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Starter Set:\u003c\/strong\u003e Display, one WN-9 node, 16 ft RJ12 cable set and T-splitter in one box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 4 Nodes per Display:\u003c\/strong\u003e Daisy-chain more WN-9 nodes for an averaged root zone reading.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeed on Demand Irrigation:\u003c\/strong\u003e Moisture-triggered watering with morning, noon and evening targets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Calibration:\u003c\/strong\u003e Pre-calibrated for rockwool; other media need only the saturated 100% point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree App Monitoring:\u003c\/strong\u003e TM+ Pro app shows history graphs and alarms with no subscription fee.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePart number\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eWCS-9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCompatible controllers\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAqua-X NFS-1\/NFS-2\/NFS-3, Hydro-X Pro HCS-2, Tent-X TCS-1, Green-X GCS-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMeasurements\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVolumetric water content, EC, temperature\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWater content range\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e0–100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eEC range\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e0–30 mS\/cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eTemperature range\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e32–122°F (0–50°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eNodes per display\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUp to 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eRefresh interval\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1 min normal; 10 sec during Feed on Demand\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eInput\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e12V, 0.1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eOperating humidity\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e≤90% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eWCS-9 sensor display, WN-9 sensor node, 16 ft RJ12 cable set, T-splitter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003ePackage dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5.43 × 6.69 × 2.52 in (138 × 170 × 64 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.39 lbs (0.63 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TrolMaster","offers":[{"title":"Default Title","offer_id":50527963611350,"sku":"WCS-9","price":189.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/trolmaster-wcs-9-main-v1.webp?v=1790264278","url":"https:\/\/growershouse.com\/products\/trolmaster-soil-moisture-ec-and-temp-3-in-1-substrate-sensor-set-wcs-9","provider":"GrowersHouse","version":"1.0","type":"link"}
