i am new to arduino i want design a blood pressure monitor using pressure sensor. which sensor is suitable for my application? from study i used mpx10dp but it shows constant values. can you please help me to get solution.
Assuming you get it to work, I don't know if you mean this for anything other than "novelty" use, but you should heed the Atmel datasheet:
Atmel products are not intended, authorized, or warranted for use as components in applications intended to support or sustain life.
I can’t see how you could use that transducer to measure blood pressure with that transducer unless you put a tee piece in a vein *
*Obviously DONT !
Please read and follow the directions in the "How to use this forum" post.
There is no useful information in your post, so don't expect help until you provide a reasonable description of your project.
