How to make a Breath Rate Sensor ?

Designing a sensor board to interface with any microprocessor board to measure Breathing Rate using a thermistor and display value in BPM (Breath Per Minute).

The Thermistor is inserted into the nostril and the changes in the temperature on the thermistor due to the breathing air will determine the pulses send to the PICAXE 28x2 chip DIO denoted as IN0 on the M28 printed circuit board for calculation. The Breath rate is then display on the LCD as Breath per minute (BPM).

You can interface it with Aurdino microprocessor, PICAXE, BasicStamp or any other microprocessor chip.
