The Heart Rate Monitor Interface (HRMI) is an intelligent peripheral device that converts the ECG signal from Polar Electro Heart Rate Monitor (HRM) transmitters into easy-to-use heart rate data. It implements a sophisticated algorithm for computing an average heart rate even with noisy or intermittent data from the transmitter.

Features

  • Multiple interfaces: USB, Logic-level serial and I2C
  • Dual heart rate processing algorithms: averaged and raw
  • Uses the RMCM01 Polar OEM receiver
  • Compatible with coded and non-coded Polar transmitters including T31, T31C, T61C and Wearlink®
  • 32-entry heart rate data history buffer
  • Four 8-bit ADC inputs
  • Up to a 5 channel digital input/output utility port
  • Simple command/response interface
  • Programmable power-on default operation
Applications
  • Custom exercise equipment
  • Portable heart rate monitoring devices
  • Bio-feedback devices
  • Heart beat aware body-worn electronics
