3-in-1 Water Content Sensor (WCS-2)

Achieving maximum yields and plant health in modern cultivation requires precise control over water content, nutrient levels, and electrical conductivity (EC). The TrolMaster WCS-2 Water Content Sensor is designed to provide real-time monitoring of the growing medium, enabling growers to optimize crop steering strategies and fine-tune irrigation schedules with ease.

This 3-in-1 sensor measures:

• Water content percentage – Ensures optimal hydration levels for plant growth.
• Electrical conductivity (EC) – Provides insights into nutrient strength for precise feeding adjustments.
• Temperature – Monitors soil and root-zone conditions to prevent heat stress.

With its advanced LCD display, user-friendly operation, and mobile notification system, the WCS-2 provides accurate, real-time data to help growers make informed decisions that lead to higher yields, improved plant quality, and efficient resource use.

Advanced Features for Professional Growers

The WCS-2 Water Content Sensor is engineered for seamless integration into commercial and home-growing setups, offering a range of innovative features:

• LCD Display and Easy Operation – Allows growers to easily monitor readings and adjust settings with a clear, backlit display.
• Addressing Button for Simple Configuration – Enables quick and hassle-free setup in diverse growing environments.
• Real-Time Measurement – Continuously tracks water content, temperature, and EC levels to provide accurate insights.
• Alarm and Mobile Notifications – Alerts users via mobile notifications when setpoint thresholds are exceeded, ensuring immediate corrective actions.

By delivering detailed, real-time environmental feedback, the WCS-2 helps growers maintain ideal growing conditions and prevent nutrient imbalances before they impact crop health.

Why Monitoring Water Content and EC Matters

Water content and electrical conductivity (EC) play a critical role in plant growth and productivity. Without accurate monitoring, plants may experience:

• Overwatering or underwatering, leading to root rot or drought stress.
• Nutrient deficiencies or toxicities, impacting overall growth and quality.
• Inefficient resource use, increasing water and fertilizer waste.

With the WCS-2, growers gain data-driven control over irrigation and feeding programs, ensuring plants receive precisely the nutrients and moisture they need to thrive.

Versatile Applications for Different Growing Environments

The TrolMaster WCS-2 Water Content Sensor is suitable for a wide range of growing systems, including:

• Greenhouses – Supports high-efficiency crop production with real-time substrate monitoring.
• Hydroponics and Soilless Media – Ensures proper nutrient strength and hydration in coco coir, rock wool, and other hydroponic substrates.
• Soil-Based Cultivation – Prevents overwatering and nutrient leaching in traditional farming.
• Controlled Environment Agriculture (CEA) – Ideal for indoor farming, vertical agriculture, and precision irrigation systems.

By integrating the WCS-2 into any modern cultivation system, growers can maximize plant performance, reduce waste, and improve overall crop efficiency.
