My system is thermal thermostat. (Climate Control)

Using thermal sensors to detect the body’s heat, according to subtle changes in body temperature to adjust the room temperature.  It keeps you stay at an appropriate temperature all the time.

With the improvement of living standards, more and more families began to install air conditioning and heating equipment, these devices bring the comfort of living also brings a very high electricity bills. It is estimated that the heater equipment, such as power consumption accounted for more than 70% of household electricity consumption per month, equivalent to the lights, computers, televisions, refrigerators, washing machines and other household power consumption is about 5 times the sum of times. Such tremendous power, not only expensive electricity bills, it is a huge waste of energy.

Energy conservation issues that need attention. How to solve this problem? After research on currently available products, nest does very well in energy-saving. The Nest is an intelligent temperature controller; it combined sensor, intelligent learning, the cloud technology. The Nest Thermostat will keep learning and adjusting its schedule, keeping an eye out for temperature changes you make regularly, but ignoring one-off adjustments.

The Nest solve the problem of energy waste is by learning and recording. I wonder if there are other ideas that would make the system more intelligent and more energy efficient?

In the beginning, I have been struggling in the wrong direction. But after I watched an animated film called Big Hero 6. In this film, the Medical robot gave me inspiration. This Medical robot is equipped with internal scanners and sensors able to detect and evaluate the threat posed by life forms in the immediate vicinity.

Then, I started to search for the human body temperature sensing system. To understand how heat transfer can be managed through design, we have to understand how the human body produces heat in the first place and the factors that affect thermal comfort (heat balance). According to the West Midlands Public Health Observatory (UK), an adequate level of wintertime warmth is 21 °C (70 °F) for a living room, and a minimum of 18 °C (64 °F) for other occupied rooms, giving 24 °C (75 °F) as a maximum comfortable room temperature for sedentary adults.

Another inspiration is the Omron D6T which is able to switch off lighting and air conditioning by sensing the body heat, and this technic support my conceptual design. So I let the thermal sensor combine with climate control.
