HVAC Vent Control

Abstract

An intelligent Heating, Venting, and Air Conditioning (HVAC) vent includes a room temperature sensor, a duct air flow temperature sensor, and a duct pressure sensor. Data from the sensors in compared to a temperature setting to determine an optimal vent louver position. A battery powered motor adjusts the louver position to optimal vent louver position. A remote device interface allows a user to monitor room temperature and to adjust the temperature setting from remote locations.
