Abstract

A device for measuring fluid includes a casing, and a weight sensing unit, a microprocessor, and a wireless communication unit. The weight sensing unit generates a weight signal corresponding to a weight of a cup and contents cup and contents rested on the casing. The microprocessor generates a control signal as to weight of the cup and contents each time the microprocessor receives the weight signal from the weight sensing unit. The microprocessor transmits the control signal to an electronic device wirelessly, commanding the electronic device to calculate current and cumulative water cup and contents each time the electronic device receives the control signal. The calculated water intake includes a current water intake and a cumulative water intake displayable for the information of the user.
