Abstract

This paper presents a compact wearable heart rate monitoring system utilizing the PSoC 6 microcontroller. The system employs an optical reflectance heart rate sensor to monitor blood volume variations and emphasizes efficient signal acquisition, adaptive digital processing, and low power operation. The weak bio-optical signals are conditioned using the PSoC's programmable analog blocks and digitized with an on-chip SAR ADC for accurate waveform representation. Digital filtering techniques improve signal quality by mitigating noise. A real-time heart rate estimation algorithm using peak interval analysis is implemented on the Cortex-M4 core to compute BPM and transmit data for visualization. Experimental validation shows that heart rate measurements align closely with those from a commercial fitness tracker, indicating the system's reliability, low power consumption, and suitability for wearable fitness devices and remote health monitoring.
