Why heart rate detection?
If you own an Android Wear smartwatch with heart rate (HR) sensor or a dedicated Bluetooth HR strap, you can use them to make sleep tracking more accurate.
How to setup heart rate detection?
For using with Android Wear or Pebble:
- Go to Settings > Wearables and enable both Sleep tracking (Use wearables) and Heart rate monitoring – Android Wear, Pebble
For using with Bluetooth HR strap:
- Go to Settings > Wearables and enable Bluetooth Smart (LE)
Now just start sleep tracking and you’re good to go! The sleep tracking screen will show a symbol every once in a while to confirm that HR data are getting through.
Sleep graph with heart rate
A normal sleep graph with heart rate detected will look like this:
The red line shows the actual heart rate value, numbers represent minimal and maximal value.
