Comparison of Signal Clarity: Earlobe vs. Fingertip

	A key finding from the testing phase is the difference in signal clarity between two common measurement sites: the earlobe and the fingertip. The data revealed that the signal from the earlobe was substantially clearer and more consistent than that obtained from the fingertip. This can be attributed to the earlobe's reduced exposure to ambient light and potentially less physiological interference such as skin thickness and peripheral circulation issues, which are more pronounced in fingertips.

			Due to the superior quality of the data obtained from the earlobe, all further detailed analyses and presentations of results utilize signals sourced from this location.

	# '''Consistency Across Detection Sites''': BPM values and signal patterns are anticipated to remain consistent between different detection sites (fingertip and earlobe), underscoring the sensor's reliability and versatility.		# '''Consistency Across Detection Sites''': BPM values and signal patterns are anticipated to remain consistent between different detection sites (fingertip and earlobe), underscoring the sensor's reliability and versatility.
	# '''Variation in Signal Clarity and Noise''': While signals are expected to show similar patterns, variations in signal clarity and noise levels may be evident between detection sites. These findings will inform potential improvements in sensor placement and design.		# '''Variation in Signal Clarity and Noise''': While signals are expected to show similar patterns, variations in signal clarity and noise levels may be evident between detection sites.
