In this paper, we implemented a system to count breath rate with a non-invasive sensor. The proposed system consists of a pad covered with a piezoelectric sensor, a breath extraction device amplifying and filtering the source signals and sending those to a viewer, and the viewer with a function of sensor data visualization and a breath counting algorithm. A breath counting experiment on three subjects was performed by changing the number of moving averages and values of thresholds. When the window size for moving average was chosen as N = 50~60 and the threshold value for each subject was customized, the proposed system showed less than 5% error rate.
