Why wear a tight bracelet when measuring heart
rate?
The bracelet adopts the principle of light reflec-
tion and collects the signal reflected to the sensor
after the light source penetrates the skin to calcu-
late your heart rate. If you wear it loosely, there
will be ambient light entering the sensor, which
will affect the measurement accuracy.
Whether the bracelet is waterproof
Support IP67 dustproof only.
