Objective: The objective of this project is to design and build a portable pulse rate meter. The device will be used to measure a person's heart rate while at rest or during exercise. A prototype device will utilize low cost components and the circuitry will be fabricated on a printed circuit board. The device will use a non-invasive measuring technique using a finger probe. Methodology: The pulse rate meter will be designed in hardware and software. The device is designed to meet the documented project specifications. The hardware modules include a power supply, detection circuit, high-pass filter, signal low-pass filter, reference low-pass filter, signal phase delay, comparator, microcontroller, and output device circuits. The software modules include a Main Routing and an Interrupt Service Routing. A verification section documents the design's performance to the given specifications. Major findings: The prototype pulse meter designed in this project met all product specifications. This project proved a low cost portable pulse rate meter could be designed. The hardware signal filtering created a signal a microcontroller could analyze and calculate a pulse rate. Utilizing the microcontroller's peripherals allowed the design to be highly integrated at low cost and small size.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .S363 2003 Item missing Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
