General Description

The operation of the AS7030B is based on photoplethysmography (PPG) and electrocardiogram (ECG).
PPG is the most used HRM method which measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the bio potential generated by the heart. The AS7030B is supported by algorithms converting the PPG and ECG readings into digital HRM, HRV and Continuous Blood Pressure values. The cuff-less Blood Pressure Measurement has been optimized to fulfill the IEEE Std 1708-2014.
The module includes the LEDs, photo-sensor, analog front-end (AFE) and sequencer as well as application software. In addition to HRM/HRV and Blood Pressure, the module also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors.
The AS7030B’s low-power design and small from factor is particularly well suited to application in fitness bands, smart watches, sports watches and smart patches, in which board space is limited and in which users look for extended, multi-day intervals between battery recharges.

This product suits for the following applications:

  • Fitness band
  • Smart watch
  • Heart rate monitor
  • Cuff less blood pressure measurements
  • ECG monitoring
  • Optical sensor platform
