The invention relates to an intelligent water pipe alarm. The intelligent water pipe alarm is characterized by comprising a shell, a control circuit board, a valve, a flow sensor, an alarm device and a power supply, wherein the control circuit board is based on a single-chip microcomputer; the control circuit board, a power supply circuit, a digital signal acquisition module and a 3G module form an integral control circuit board; the control circuit board is connected to the valve, the flow sensor, the alarm device and the power supply to form an intelligent water pipe alarm device; the valve and the flow sensor are connected to a water pipe; and the intelligent water pipe alarm device is fixedly connected to a shell. The intelligent water pipe alarm has the beneficial effects that whether the water pipe is abnormal is judged by measuring the time or flow of continuous flowing water, thereby carrying out processing; meanwhile, the intelligent water pipe alarm belongs to one part of smart homes and internet of Things; due to installation of a networking communication module, cell phone numbers of users, property management departments and the like can be input and stored by an operation panel; and when water flow is abnormal, information of water flow abnormity can be timely sent to the stored cell phone numbers.
