3-in-1 Moisture Sensor (WCS-2)

The Water Content Sensor (WCS-2) by TrolMaster addresses the need for precise nutrient control in high-yield crops, offering constant measurements of water content, temperature and electrical conductivity (EC) in the growing medium. Its design includes an LCD display to facilitate operation, a directional button and the ability to set alarm limits for mobile notifications through TrolMaster or TM+ applications.

Each WCS-2 comes with a sensor with 5 prongs that you'll insert into the growing medium (compatible with any growing medium). Note that the sensor must be in horizontal position and in the upper 1/3 of the pot or rock wool block.

You can connect up to 50 units to the HCS-2 controller. Beyond monitoring parameters, the system allows you to set alarms that alert if these parameters fall below or exceed certain values.
