SKU: IFT00128-2 Category:


  • Heart Rate click carries Maxim’s MAX30100 integrated pulse oximetry and heart-rate sensor. It’s an optical sensor that derives its readings
  • from emitting two wavelengths of light from two LEDs – a red and an infrared one – then measuring the absorbance of pulsing blood through a
  • photodetector. This particular LED color combination is optimized for reading the data through the tip of one’s finger. The signal is
  • processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS I2C interface. Developers of
  • end-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much
  • pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses
  • 3.3V power supply.
  • Key features:
    Optical sensor: IR and red LED combined with photodetector
    Measures absorbance of pulsing blood
    I2C interface plus INT pin
