The optional Smoke Detector (MBS-SD) can alert the user to smoke within their growing area at ALL TIMES. Up to 5 smoke detectors can be connected to a single Hydro-x controller. If ANY of the smoke detectors determine there is smoke in the area, the user will receive a user-alert on their phone to alert them to the potential problem BEFORE the problem gets out of hand. "Sensors should remain dry and clean to prevent premature failure. Do not spray foreign substances or allow water / condensate on the sensors"

Beautiful touch screen display.  It has an 800x480 7” LED display monitor and can control an unlimited number of lights, 8 temperature devices, 8 humidity devices, 4 CO2 devices, and 12 programmable timer devices (up to 50 schedules can be created). With incredible flexibility and the expanded product capacity, anyone can now easily customize their own grow room control system for maximum yields. Having multiple control modules also provides the option for the user to create multiple "stages" of growth. By staggering the start times of each stage, the user can minimize the amount of time that plants spend in vegetative growth and focus on the flowering phase. Having multiple control modules also provides the option for the user to create multiple "stages" of temperature and humidity control, which will provide a more stable environment. The HCS-3 system comes with an MBS-PRO 4-in-1 sensor to measure temperature, humidity, CO2 ppm, and the presence of light. Lighting control has never been easier or more capable. The optional MBS-PAR light sensor can be added to the system. It will automatically adjust light intensity to precisely provide the exact amount of illumination for optimum plant growth. The Hydro-X Plus has been can also track your DLI levels. Having 2 separate lighting control channels allows the user to create multiple lighting layouts (and dimming sequences) based on their individual preferences. Besides controlling your room, if a problem is detected by the HCS-3, a warning message (notification) will be sent to your smartphone. Up to 10 smoke detectors and 10 water leak-detectors can be connected to the HCS-3 which will alert you if there are any fire or water leaks. The HCS-3 also offers multiple advanced functions to control your entire grow room or greenhouse such as Sunrise / Sunset simulation, DLI control, overheat protection, Spectrum & Group lighting control, and more.
