Heart beat monitoring system

• Pin It

In this project we will see how to build a heart rate detection system, we use a pulse sensor and an OLED display, all controlled by an Arduino Nano.

The sensor detects the person heartbeat and converts it into electrical signals and pulses. The signals are amplified using a signal conditioning circuit and processed by a controller, in this case Arduino Nano.
The pulse sensor is therefore able to record heart rate and heart rate variability (HRV) and can be connected directly to, for example, an OpenBCI.
