Core's biosensors use an electrocardiogram (ECG) to measure your body's response to your meditation session. If you see the No sensor data found message, that means Core wasn’t able to get reliable biometric data from the session. This can happen for a couple of reasons:
- Your hands weren't in full contact with Core's sensors. This doesn't mean you need to completely cover the sensors, or apply pressure, but try to keep your thumbs in contact with at least a few metal dots on each side. You'll see two lights light up in between the sensors when you've made appropriate contact.
- Core may struggle to measure your biometrics if you have light circulation in your hands and fingers or are especially cold when you meditate. If this is an issue for you, try warming your hands before your session.
If you're still having issues after giving these a try, please reach out to us at firstname.lastname@example.org and we'll help get things back on track.
