WCS-3
The TrolMaster WCS-3 water content sensor is specifically designed to measure the moisture level (in percentage) of the growing medium. The WCS-3 can be used with the TrolMaster Aqua-X (NFS-1), Aqua-X Plus (NFS-3), Aqua-X Pro (NFS-2), Hydro-X Pro (HCS-2) and Tent-X (TCS-1) control systems. Each WCS-3 sensor is a 3-pin volumetric water content (VWC) sensor. To use the WCS-3, you must insert the 3-pin sensor into the growing medium such as coco coir, soil, or rockwool to be measured. You can connect multiple media moisture sensors to a single controller. Up to 50 WCS-3s can be connected to the NFS-2 and HCS-2 controllers, 20 on the NFS-3, 8 on the NFS-1 controller, and 1 on the TCS-1 controller. *NOTE: The TCS-1 can only have one WCS-3 connected. Each WCS-3 has an integrated LCD screen on one side of the sensor that becomes "active" and can be viewed when the sensor is shaken or disturbed. The screen will display the current VWC% reading directly on the sensor.
