I like the idea from this project too much to let it die.
Let's give it a spin this summer!

An even bigger surprise was when I realized that the sensor is so sensitive that it can detect with no problems the breath temperature.

That was the moment when the applications start to arise:

- breath counter

- lungs thermometer (by monitoring the exhaled air temperature)

- breath logger

- breath parameters monitor, i.e. the ratio between exhale and inhale time

- athletes training/monitoring equipments

- breath exercise training (helping techniques for yoga breath, voice singers, etc.)

- instant skin temperature measurements and so on

The surprise was when the device could easily detect a finger touch of the sensor. That was because the thermal inertia of the sensor is very small, and the finger instantly change the sensor's temperature. Nice.

At the beginning, a very simple algorithm was implemented. The microcontroller read the sensor by I2C interface and changes the color of a LED when an increase/decrease in temperature is detected.

This idea has born by a simple curiosity about an I2C sensor produced by Texas Instruments. The sensor is very sensitive, it has an incredible resolution of only 62.5 mili Celsius grades (*C).

I will add one more ideea to the competition, then came back here and update this project
