TrolMaster Hydro-X Pro Controller with 4-in-1 Sensor (Temp / Humid / CO2/ Light ) and Cable set, Free Phone App TrolMaster revolutionized environmental controller technology when it introduced the Hydro-X. The Hydro-X Pro continues the revolution with a 10’ touch-screen and a web-based software. The Hydro-X Pro is backwards compatible with all current Hydro-X control / device modules. It also provides greater flexibility and allows any plug-in module to be addressed to be whatever the user wants. The user can also set up each plug-in module to have multiple “conditions” that will activate the module, allowing for almost unlimited control options. The Hydro-X Pro expands the capability of the original Hydro-X by allowing up to 50 sensors and up to 50 separate control modules to be connected to a single Hydro-X Pro. Even it is still deigned to be a single room system for reliability and ease-of-use, multiple sub-zones within the grow space can be monitored and controlled separately by linking a specific sensor (or average) to a specific control function(s). The new 4-in-1 sensor comes with a LCD screen which provide the ease of onside monitoring. Customized programming allows almost limitless degree of control. Each of the variables (Temperature, Humidity, CO2, Light) can be controlled independently, meaning a customized ramp-up / ramp-down can be used to closely simulate natural outdoor conditions, or simply allow complete customization of the environment. Displayed on an easy-to-read and construct “graph” it allows the user to have 100% control of their environment. Another powerful feature of the Hydro-X Pro is the built-in calendar and calendar presets that allows the user to schedule an entire crop’s “recipe” within the Hydro-X Pro. All settings including Lighting, Temperature, Humidity, CO2, and Timers can be specified by the user as they “build” their multi-week crop schedules. Reminders can also be programmed to ensure critical tasks are not forgotten. The TrolMaster APP will also allow for notifications with separate day/night limits to be received by the user. The web-based software provides easy access and more advanced remote control. Onboard data acquisition and the ability to store and share setting between multiple devices, means that user-defined programs & settings can be saved and loaded into multiple Hydro-X Pro units with ease. A personalized screensaver page can be uploaded through a USB port. The same upgradeable feature like Hydro-X gives you the ability for life-time improvements.
