1. A clip-type monitoring device for wirelessly transmitting the heart rate, comprising:

  • a) a housing having a clip at the back thereof, the clip being clipped onto the clothes, a jack being formed at the flank thereof for receiving an external signal;

    b) a heart rate monitoring unit having a plurality of electrode pads extending out of the housing and staying close to the human body'"'"'s chest to monitor the pulsation, each of the electrode pads being connected with a conducting wire, a plug being provided at a influx terminal for electrically coupled to the jack such that a measured voltage variation rate is transmittable to the inside of the housing;

    c) a voltage sensor unit disposed within the housing and provided with three inductors and a filtering shaping amplifier circuit so that the voltage variation frequency measured by the heart rate monitoring unit is filtered by the inductors and then transmitted to the filtering shaping amplifier circuit to receive an amplified signal;

    d) a control interface provided on the surface of housing to control the heart rate monitoring unit and the voltage sensor unit to turn ON and OFF; and

    e) a radio frequency module having a wireless signal transmission circuit and provided in the housing for transmitting the signal amplified by the voltage sensor unit to a display storage device provided with a wireless signal receiving circuit.
