Project Overview
• The centralized air conditioning system does not always cool or heat different regions of a building uniformly
• Network of Smart Air Vents that facilitates uniform cooling of a building through air flow control
• Owners of buildings with centralized air conditioning
• Cost of prototype: $143.31
