It's a heart rate monitor intended for wearable tech. Cost just under $5 in unit quantity.

A bubble gum is cheaper than a Pi Zero. And about as comparable to a Pi Zero.

What are you getting at exactly?

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.

The other thing I'm getting at is that here is a (potentially) useful device that could be made to work with a Pi Zero that, for a change, costs less than the Pi Zero itself.

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.

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.

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.

Can you post the make and model, I'm blocked from there with our 'network security'

Thanks, the evaluation board for the AD8233 is not a lot either, more than a Pi3 though.

Since it looks new, I guess it'll be a wait for a Alibaba special.
