Building a heartbeat monitor with the Raspberry Pi

Daniel Fernandez has taken a Raspberry Pi, a Polar H7 heart sensor and a 3.5″ screen and created a heart monitoring system. The system allows you to wear the sensor, which sends readings to the Raspberry Pi which then graphs the results in real-time. A 3D-printed case completes the project, along with the software which he’s made available on GitHub. Read more over at The MagPi.
