The goal of the project is to build a device that able to constantly monitors heart rate and stores the data on an SD memory card. The data can be read from the card, imported into MS Excel (or other programs) for graphing or other analysis. The heart rate data logger project consist of Arduino microcontroller, Adafruit data logging shield for arduino, Polar heart rate module RMCM01, Polar T31 heart beat transmitter, and 32.768KHZ crystal.
