With the growth of age, the memory, intelligence and thinking will decline for most people. To avoid the injury or life in danger resulted from forgetting to turn off the running water switch, a special switch to measure and control the running water flow for aged was proposed. Two kinds of sensors including flow sensors and distance sensors were applied in the device to guarantee that the switch should be turned off before water in the container comes out. The configuration of the device was designed to use conveniently for aged. The required flow was firstly input on the board set on the water supply line, then the switch could be turned on and the flow sensor works to measure the water flow required. Once the flow value is up to the set value on the board, the switch could be turned off by the controller in the circuit. To guarantee the safety on the sensors in the process of the measuring, another two distance sensor were chosen and set on the running water port to complete the measuring work of the water level in the container to avoid the water coming out from the container secondly.
