Note: It is important to power the module with a separate power supply and not connect it to any other circuit. If the power supply is shared with other connections, ensure that the negative pole of the supply voltage and the detection voltage can be connected together. Also, make sure to set the module when no voltage is detected on the interface. If the interface has unsafe voltage, use an insulated object to press the buttons, and avoid using your hands.
