Abstract
A climate control system that detects presence of a person in a room by analyzing small fluctuations in barometric pressure due to breathing. When the room is occupied, thermostatic control by the occupant may be enabled; when unoccupied, HVAC systems may be set to a low-power state. Barometric data may be processed using a bandpass filter that passes frequencies that correspond to typical human respiration rates. Barometric data may be used to determine when doors or windows are open or closed. Embodiments may connect to property management systems determine whether occupants are expected; when a room unoccupied but an occupant is expected, HVAC systems may be set to a standby state that saves power but allows temperature to return quickly to desired levels when a person enters the room. Occupancy detection may also use data from other sensors such as gas analyzers that detect compounds in exhaled breath.
