I'm looking for both wearable hardware and software for heart rate monitoring on linux. On wrist or chest strap is fine.
Heart rate monitoring is essential. Oxygen saturation and ECG functionality would be nice too. (...)
(...) The Medtronic Zephyr system has an open API that uses Bluetooth Classic, BLE or USB. It is a wearable patch but it is not cheap:
I've owned a Zephyr HxM for ~10 years, it's the more affordable (<$100) consumer version, chest strap HRM only (no SpO2 or ECG). It was purchased prior to the Medtronic acquisition, but I assume it's essentially the same product. The mobile SDK isn't free ($25USD), but the protocol is documented, and there's a few open source libraries to collect data. There are plenty of existing android apps that simply monitor/graph the heart rate, and provide CSV export of the data, no online service required. I'd probably use R for visualisation and analysis, but only because I'm already familiar with it. As always, your experience may vary. ~ Joel
