It depends on what you're looking to measure. It looks like pyHRV would work with the output from the existing sensor. There's another thread with some discussion about blood pressure monitoring with similar sensors. A retrofit with a different sensor should be relatively easy, but probably needs a new back cover, which would add significant tooling costs for production. At them moment we're benefiting from the hardware being an existing mass produced design, but if the PineTime becomes a volume product that sort of alteration may make sense. As it stands a replacement sensor with a 3d printed back cover might be good enough for medical researchers or those interested in self-monitoring.
