as a part of my project,digital heart beat counter, in order to sense the heart pulses from the wrist, we selected a piezoelectric sensor.
the sensor is working fine, it detects the pulse in the wrist..
sensor convert pulse to mV range..
but the problem is , the sensor detects even a small movement of hand too..
so in order to, take the pulse correctly , we have to keep the hand still for 1 min..
can any one suggest anything, to avoid this?
thanks
