Central Environmental Control System

greenhouse-controllerA computerized control system coupled with a weather station can control the different operating parameters required for normal greenhouse operation as well as anticipate changes such as increased wind speeds or rain may dictate the need to close vents or low solar levels during cold weather may dictate closing thermal blankets and turning on supplemental lighting. These systems can also alert personnel to equipment failures or parameters that are outside of control limits by an audible alarm, light text message or telephone call. These control systems save energy due to smaller differential ranges on sensors, using the same sensor and controller for fans and the heating system so they aren’t running at the same time and anticipating changes that reduce energy input and increase plant growth. A basic controller to control heating and ventilation with functions to do DIF and have alarm functions will cost about $500.
