Abstract :
The digital sensor module is developed to sample the input signal fed from a photo-sensor probe at sampling times ranging from 400-4000 mus equivalent to sampling rates of 2500- 250 sample/second (S/s), respectively. The module produces 16-bit data packets which are transmitted serially and plotted to output the photoplethysmography signal (PPG). It displays accurate sampling values (packets) similar to the calculated ones.
