The PWR pin is connected to the second end of the third transistor Q3, the EN pin is connected to the control end of the third transistor Q3, and the INT pin is connected to the activation module. Referring to the above embodiment, when the signal processing unit 140 receives the activation signal, the third transistor Q3 is turned on, the PWR pin of the signal processing module 140 is at a high level, and the PWR pin of the signal processing module 140 is continuously maintained at a high level because the third transistor Q3 can be maintained in the on state. The analyte measurement module includes a DOUT pin, a GND pin, and a VDD pin, where the VDD pin is connected to the PWR pin of the signal processing module 140, that is, when the detection device is activated, the signal processing module 140 receives an activation signal, so that the third transistor Q3 can be kept in a conductive state, and the analyte measurement module is powered on by the VDD pin, and when the detection device is not activated, the analyte measurement module is not powered on and is in a power-off state, thereby reducing the power consumption of the analyte detection device.
