Ultra Low Power Blood Pressure And Heart Rate Monitor Reference Design


Design files


This reference design is a demonstration for detecting blood pressure and heart rate. It works in low-power mode(LPM3) and only displays the date and time in most time. User can measure blood pressure by pressing 'measure' button and also can look at historical blood pressure by pressing 'memory' button. The measured records will be stored in EEPROM after measurement complete. The max record number is set as 80.

  • Ultra low power in standby mode(standby mode: LPM3+RTC+LCD)
  • Battery powered, portable electronic
  • MCU with LCD driver, One chip solution
  • Easy to use, two buttons, 4 operation modes
  • Support raw data read out
