  • I had the same idea - a DIY pulse oximeter. If anyone knows of existing designs, please let me know. I plan to connect this sensor to a “teensy” arduino-compatible board, shine a white LED on one side of a finger and this sensor on the other. If I can get heart rate from that, great! If I can get oxygen levels, even better though I suspect thats much harder to deduced from the input data.

  • the description for the ID-2 reader says it needs an antenna. does this base unit also provide an antenna?
