It is built around five sensors that work together to track various aspects of your health:
- Optical blood flow sensor – This sensor detects heart rate, through pulse or blood flow, and constantly monitors heart rate. This is the most important sensor and provides the device with key metrics so that it can understand how the body is reacting to lifestyle
events. - 3D accelerometer – Highly sensitive, this sensor detects even the smallest movement, regardless of whether users are alert and active or sleeping soundly.
- Body temperature – By measuring the user’s skin surface temperature, this sensor provides a more accurate reading of exertion in an activity state.
- Ambient temperature reading – This sensor detects the outside temperature and, in relation to body temperature, can boost the accuracy of caloric burn calculations, as well as providing insights into other environmental effects on the body.
- Galvanic skin response – By measuring the intensity of the skin’s moisture output (or sweat) during any activity, from warm-up to recovery, this sensor provides information particular to an individual’s level of exertion when engaged in activity.
The major issue is
1.Basis B1 don't provide open API
2.Basis B1 seems still use Bluetooth 2.x protocol. Not BLE.
