What is PPG Heart Rate Technology?

PPG (Photoplethysmography) is the process of detecting volumetric changes in blood peripheral circulation using optical LED lights. The LED emitter shines light through the skin surface and measures changes in blood flow and light absorption. 


The rate of flow in the blood vessels and capillaries is processed through a sequence of noise filtering algorithms and sampling rates to detect R-R intervals and heart rate (BPM). During intense exercise the rate of flow increases substantially and the PPG sensor calculates the beats per minute (BPM) by sampling the rate of flow hundreds of times per second.

USB Fast Charging 

Optic supports up to 18 hours of battery on a single charge from a 140mAh lithium polymer battery. The LED light will flash Green and Red when the battery is low and needs a charge. 

The charging cable uses a magnetic pin style terminal that stays securely attached to the sensor during charging. When on charge the LED light will flash Green and stay solid Green when fully charged.
