Abstract

A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

First claim

What is claimed:

1. A wireless remote sensor for managing an indoor climate system, the wireless remote sensor comprising:
a housing that fits into a wall box;
an environmental data collector, wherein the environmental data collector comprises a thermometer and a hygrometer;
a memory configured to store data collected by the environmental data collector and a database of human identification characteristics, wherein each one of the human identification characteristics is associated with a climate profile corresponding to a human; and
a processor coupled to the memory and the environmental data collector, the processor configured to:
detect the presence of the human in a zone;
compare characteristics of the detected human with the database of human identification characteristics stored in the memory to determine the climate profile corresponding to the human;
transmit, to a HVAC control unit, the determined climate profile;
determine a temperature measurement and a humidity measurement associated within the zone; and
transmit the temperature measurement and the humidity measurement to the HVAC control unit, wherein the HVAC control unit adjusts the airflow to the zone based on the temperature measurement and the humidity measurement.

2. The wireless remote sensor of claim 1 , wherein the wall box is a light switch box,
further comprising a touch screen, and
wherein the processor is further configured to act as a virtual light switch based on user interaction with the touch screen.

3. The wireless remote sensor of claim 1 , wherein the wall box is an electrical outlet box, further comprising at least one socket for accepting an electric plug.

4. The wireless remote of claim 1 , further comprising a camera, and wherein the processor is further configured to detect the presence of the human using facial recognition software.

5. The wireless remote sensor of claim 1 , further comprising a microphone, and wherein the processor is further configured to detect the presence of the human using voice recognition software.

6. The wireless remote sensor of claim 1 , wherein the environmental data collector further comprises a gas detector capable of measuring carbon dioxide concentration in the air.

7. A method for managing an indoor climate system, the method comprising:
storing data collected by an environmental data collector that comprises a thermometer and a hygrometer, and a database of human identification characteristics, wherein each one of the human identification characteristics is associated with a climate profile corresponding to a human;
detecting the presence of the human in a zone;
comparing characteristics of the detected human with the database of human identification characteristics stored in the memory to determine the climate profile corresponding to the human; and
transmitting, to an HVAC control unit, the determined climate profile;
determining a temperature measurement and a humidity measurement associated within the zone; and
transmitting the temperature measurement and the humidity measurement to the HVAC control unit, wherein the HVAC control unit adjusts the airflow to the zone based on the temperature measurement and the humidity measurement.

8. The method of claim 7 , further comprising detecting the presence of the human using facial recognition software.

9. The wireless remote sensor of claim 7 , further comprising detecting the presence of the human using voice recognition software.
