temperature or touching the corrosive as strong acid or alkalis material.
2. Wetting the skin, where will contact the conductive area of the chest belt will
improve the conduction and get more stable signal.
3. The physical condition of individual might affect the intensity of measured
signal.
4. Avoiding using the heart rate monitor close to trolley car, tram stop,
transformer, electric substation and high-tension distribution line etc.
Because the radio signal will be affected under the environment as high
voltage and strong magnetic field.
