The CORE sensor allows the live and recorded data to be accessed in a few ways. Please refer to the CORE connectivity for an overview of the compatible hardware.
The CORE sensor captures core body temperature (CORE temp) and skin temperature (Skin temp) data. From this data, the CORE sensor calculates your Heat Strain Index (HSI) in real-time. Which of these metrics can be viewed on compatible devices can vary. Please refer to our connectivity guides for more details
There are two ways that that data from the CORE sensor is recorded and is available for further analysis.
1 - CORE sensor activity data - FIT file
Sports devices that can be paired with the CORE sensor allow the real-time data to be displayed on-screen and most record this to the FIT file - a standard format which is common for sports hardware to log training metrics.
This data is typically available after an activity in the sport device and companion apps/software. FIT files are a universal format that can also be opened in sports applications.
2 - CORE sensor (onboard) recorded data
The CORE sensor records temperature data on-board and independently to FIT file recording. This is a second source for the data which is synchronized via the CORE App and permanently stored.
The CORE sensor records core body temperature (CORE temp), skin temperature (Skin temp) and, when available, heart rate (bpm). When synchronized via the CORE App, the data is then available inside the CORE App along with advanced metrics.
