nrf51822 heart rate sensor

[ericzhao]

HI

I'm trying to connect a heart rate sensor to nrf51822 but I cannot find a suitable sensor. Could you please recommend a heart rate sensor which nrf51822 can support?

Thank you!

Some nRF51822 based fitness trackers use the SI1143

However I'm sure there are probably other sensors that you can use depending on your precise requirement and the method of sensing needed
