Overview

This design details how to build a digital heart-rate monitor using a MSP430FG439 microcontroller (MCU). The heartbeat rate per minute is displayed on an LCD and generates a digital data stream via an RS232 serial port to allow EKG waveform display on a PC. The entire application runs using a CR2032 3-V lithium battery.

Features

Integrated AFE with external INA for low-power two-chip EKG measurement
Low cost PCB-based sensors
Integrated segmented LCD display for easy pulse readout
GUI application support for display of measured results via PC
This application report uses the MOD-EKG Pulse oximeter and Heart-Rate Monitor using the MSP430FG439 development board by OLIMEX Ltd
This reference design is tested and includes software, hardware design files, documentation & PC GUI.
