I'm getting at that a consumer grade version of a medical device (heart monitor) is now less than $5. Add an ADC and hook it to a Pi and you've got a really inexpensive EKG machine. Not up to professional standards, sure, but probably at least as good at this particular function as a Fitbit or Apple Watch....for a great deal less.Heater wrote:A bubble gum is cheaper than a Pi Zero.

What are you getting at exactly?
Very interesting device - just over $3 in 1000 count volume. It has I2C - so easy hookup.
From the "heart rate monitor" description it wasn't immediately obvious that it's a lot more than that. It does look interesting and probably a lot safer than what some people come up with as DIY EKG/ECG monitors. The two lead non-driven mode, similar to Polar and other modules which strap around the chest, is probably the best and safest to start with.W. H.

Any link to example to hook up to a Pi? Or any modified to work with the Pi. For good old datalogging and stat overload.mjtessmer wrote:There is another alternative to measuring heart rate; pulse oximeter. It can also measure
percentage of oxygen in the blood. Cost as low as $11.59.
