Trolmaster - Sensor Board (AMP-3)

The TrolMaster AMP-3 Sensor Board is designed to connect precision pH, EC and temperature sensors to compatible TrolMaster control systems such as the Aqua-X Pro and Tent-X controllers. In hydroponics and automated indoor growing environments, monitoring nutrient solution conditions is essential for maintaining healthy root development, stable nutrient uptake and consistent plant growth.

The AMP-3 acts as a bridge between the controller and compatible probes, allowing growers to track reservoir or irrigation solution conditions in real time. Once connected, sensor data such as pH levels, electrical conductivity (EC) and water temperature are displayed directly on both the AMP-3 LCD screen and the main controller interface. This provides growers with instant visibility of nutrient solution conditions within their hydroponic systems.

Multiple AMP-3 units can be installed within a system, allowing growers to monitor different reservoirs or irrigation zones within larger grow rooms.

Key Benefits

• Connects pH, EC and temperature probes to compatible TrolMaster controllers
• Designed for use with Aqua-X Pro and Tent-X systems
• Real-time monitoring of nutrient solution conditions
• LCD display for on-site monitoring of sensor readings
• Supports multiple sensor boards within a single system
• Plug & play installation with RJ12 connectivity
• Helps maintain stable nutrient conditions for improved plant health

How It Solves Grow Problems

In hydroponic systems, nutrient solution conditions can change rapidly as plants feed and environmental conditions fluctuate. If pH or EC levels move outside the optimal range, plants may struggle with nutrient uptake, leading to slow growth, deficiencies or reduced yields.

The AMP-3 allows growers to continuously monitor these critical parameters by linking precision probes to the control system. Real-time data helps growers quickly detect changes in nutrient conditions and make adjustments before plants are affected.

By maintaining balanced reservoir conditions, growers can support stronger root development, healthier plant growth and more consistent yields throughout vegetative growth and the flowering stage.
