| description | The utility model relates to a water leakage detection circuit and equipment, and the circuit comprises a power supply, a control circuit, an adjusting circuit, an electrode body, a shunting circuit, and an alarm circuit. The control circuit is used for transmitting pulse signals to the adjusting circuit; when the electrode body is in contact with water, the first end of the electrode body is connected with the second end of the electrode body, and the electrode body and the shunt circuit form a parallel branch; the adjusting circuit is used for providing preset current for the parallel branch according to the pulse signal; the control circuit is also used for detecting the voltage of the first end of the shunt circuit to obtain an acquisition voltage, and transmitting a driving signal to the alarm circuit when the acquisition voltage is smaller than the trigger voltage, so that the alarm circuit emits alarm information. The water leakage detection circuit is high in detection sensitivity and can detect water |
