EVM430-FR6043: Breath measurement and Spirometry using Ti Ultrasonic solutions

Part Number: EVM430-FR6043
Other Parts Discussed in Thread: MSP430FR6043


We are starting a design of an ultrasonic spirometer using ti 
MSP430FR6043 and we are looking for recommendations for the design using the same.

Could you please help us with some pointers for the same?

Kind regards


  • Hi VG,

    We do not have much experience on the spirometer application. I suppose it is similar to the gas meter. However, there are some challenges occur to my mind. You need to control the humidity of the air. Put a sponge on the blower side would help. And the flow rate calibration with temperature would also need a lot of effort. 

    Best regards,
