When using the CORE sensor for sports and exercise, you should pair the sensor to a heart rate monitor as this will ensure that the results (during the sporting activity) are accurate.
The CORE sensor can be paired to most heart rate monitors including chest straps and watches that broadcast over ANT+ or Bluetooth.
How to pair a Heart Rate Monitor to your CORE
1. Open the CORE App on Android or iOS and make sure that you are connected to your CORE sensor
2. Click on the 'Settings Icon' - top right of your CORE
3. Scroll down and click on "Manage heart rate monitors"
4. Click on 'Add Sensor' and then 'Start scan'
5. Select the Heart Rate Monitor to complete Pairing.
Checking if the heart rate monitor is connected.
You can confirm that the heart rate monitor is connected in two ways:
Inside the CORE app when it is connected the 'heart' icon will be displayed in green and the current beats per minutes displayed.
Alternative you can shake the CORE sensor and look out for the green LED light. The initial light sequence indicate the battery charge, this is followed by a single or double fast flash (which repeats for two minutes). A single flash indicates no heart rate monitor is connected, a double fast flash indicates that the CORE sensor is connected to a paired heart rate monitor.
Multiple heart rate sensors can be paired with a CORE sensor and it will connect to the first one it detects.
You only need to pair a heart rate monitor once to your CORE sensor. The CORE sensor will look for paired heart rate monitors and connect automatically.
It is convenient to leave the CORE sensor clipped to the heart rate monitor strap.
Types of heart rate monitors
For sports there are two common types of heart rate monitors and the quality of the measurements can vary - this in turn can impact the core body temperature measurements when the heart rate measurements are poor.
A traditional heart rate monitor that uses electrocardiography (ECG) sensors. The ECG heart rate monitors provides the most accurate data and is typically worn on a chest strap. Sometimes these are also integrated into clothing / sports bras.
PPG (photoplethysmography) heart rate monitors are integrated into smart watches. These 'optical' sensors use light pulses to measure heart rate and are not as accurate as the ECG monitors. The CORE sensor will work with them, but the accuracy of temperature measurements may decline.
Some PPG heart rate monitors are worn on an arm band and while still not as accurate as an ECG sensor, the arm placement delivers much more accurate data than the wrist / watch sensor.
