Abstract
The utility model discloses a reminder for infant bedwetting. The reminder comprises a power supply circuit, a temperature sensing circuit and a voice circuit, wherein the voice circuit comprises a loudspeaker, a fourth transistor, a voice integrated circuit, a third resistor, a fourth resistor and a second capacitor, and the temperature sensing circuit comprises a temperature sensor, a first transistor, a second transistor, a third transistor, a delay capacitor, a potentiometer, a diode, a first resistor and a second resistor. The resistivity of the potentiometer is adjusted, so that the reminder action delay time after the infant bedwetting is changed. The resistivity of the third resistor is changed, so that the tone of the reminder is changed. The reminder sounds the voice warning tone within a few minutes after the bedwetting of the infant occurs. The reminder has the advantages of being simple in circuit, stable in performance and convenient to install and debug.
