Heart rate test module of many transmitting illuminants

The utility model discloses a heart rate test module of many transmitting illuminants, include: the circuit board, install in on the circuit board quantity be no less than three emitting diode and install in photistor on the circuit board, emitting diode sets up around the photistor, after installing on the circuit board, the photistor highly is greater than the height after emitting diode installs on the circuit board. The utility model discloses an increase emitting diode's quantity, can effectively solve when carrying out heart rate test than cold day gas or to the darker people of the colour of skin, the more weak or condition of can not receiving effectual signal of signal that the photistor was received, the degree of accuracy of promotion heart rate test, simultaneously, highly be greater than the height after emitting diode installs on the circuit board after the photistor is installed on the circuit board, can effectively reduce the interference that emitting diode direct irradiation photistor brough
