Heart rate monitors measure the heart rate during exercise or vigorous activity and gauge how hard you are working.
Newer heart rate monitors consist of two main components: a signal acquisition sensor/transmitter and a receiver (wristwatch or smart phone).
In some cases, the signal acquisition is integrated into fabric worn by the user or patient. MCUs analyze the ECG signal and determine the heat rate, while an 8-bit MCU can suffice for a simple heart rate monitor.
For more complex analysis, such as heart rate variability, activity level and breathing rate, a high-end 32-bit MCU may be used.
