Arduino + MLX90614 Infrared Thermometer Module (Read 3431 times)
The MLX90614 is a non-contact infrared thermometer with a measurement range from -70 to +380 degree Celsius. Just connect the four leads to your Arduino and you will have a accurate thermometer with a resolution of 0.01 and a accuracy of 0.5 degrees. The code below reads the object temperature which is emitted from the objects surface and the ambient temperature from the sensor itself.

Thought about Theme
Entire energy contains environmental energy and a person's energy (same as F(Qi)).
Both elements are balanced and interacting each others.
Formally, Entire Energy of the Sphere= Environmental Energy in the Sphere + F(Qi)
F(Qi) = a one's (blow + heat + movement)
I will set up the environment with light form.
A person will interact with environmental energy that are represented by Light energy in order to keep balancing or being harmonious.
In addition, the light energy implies visible energy, so becoming invisible energy is the same amount of the invisible energy that the person absorbs.

Jim Campbell - Scattered Light
Jim Campbell: Scattered Light in Madison Square Park, New York City, October 21 through February 28, 2011.
The LED bulbs, programed to flicker scattered light, create the illusion of figurative images that explore and reflect the human experience amidst the urban landscape, creating the appearance of giant human shadows crossing a floating 3-D matrix of light. As one travels around the piece, the vantage point alters and the light figures begin to abstract, blurring the boundaries between image and object.

Visualizing One's Blow

How Does It Work?
1.Holding a small ball
2.Blowing on a small boll while walking around in the booth
3.the mood color of the inner booth changes depending on the user’s heat
4.Silhouette follows a user: The shadow implies Lights on the wall loose their energy
5.The small ball lights up as much as the strength of the blow
