Urine detection method and urine detection device

A urine detection device, attached to a diaper to be put on a human body, comprising:

• a main body;
• a capacitive humidity detection unit disposed on the main body, having a sensing electrode, wherein when the main body is attached to an external surface of the diaper, and is devoid of contact with a human body, the sensing electrode forms a capacitance value with the human body;
• a processing unit disposed on the main body, the processing unit being connected to the capacitive humidity detection unit and configured to record a preset critical capacitance value, wherein when the processing unit receives the capacitance value, the processing unit compares the capacitance value with the preset critical capacitance value, when the capacitance value is greater than the preset critical capacitance value, the processing unit generates a reminder signal, wherein an environmental capacitance value is recorded once every minute, an average capacitance value is obtained by averaging the environmental capacitance values, and the preset critical capacitance value is 15 to 40% greater than the average capacitance value;
• and
• a reminder unit disposed on the main body, the reminder unit being connected to the processing unit, wherein when the reminder unit receives the reminder signal, the reminder unit generates a reminder.
