NEW GUIDE: Pulse Oximeter Wireless Data Logger @adafruit @johnedgarpark #adafruit

With this brand spanking new guide, you can measure your blood oxygen level and pulse rate using a fingertip pulse oximeter and log that data wirelessly onto an SD card! Bring the comma-separated log file into your graphing software or quantified self apps for total control of your data!

Using a Feather nRF52840 Express with the Adalogger FeatherWing for real-time clock and SD card read/write capabilities. Code it all in CircuitPython and you’ll be automatically logging data each time you use the pulse oximeter.
