The invention relates to the technical field of human body existence detection, and discloses a human body existence detection method, which comprises the following steps that: a millimeter wave radar module detects the frequency of radar waves in real time, and calculates the difference value of the detected frequencies of two adjacent radar waves; judging whether a human body exists in the detected space range or not according to the frequency difference; if the human body exists, judging whether the human body moves; human body activity: judging the state of the human body activity; human body activity: acquiring the amplitude of the human body activity; the millimeter wave radar module outputs detected data to the CPU management unit, and the CPU management unit drives the alarm indicating lamp and the alarm horn to send out alarm information according to the received data. The detected data comprises a human body existence identifier, a human body activity identifier, a human body activity state value an
