US Patent 9230423 Drinking reminder apparatus and method

A drinking reminder method is implemented by an electronic apparatus. The apparatus includes a scale pan, a weight sensor, an analog/digital (A/D) converter, a display screen and a keypad. The keypad includes a power key, a reset key and a switching key. The weight sensor senses an analog pressure signal when a cup filled with water is placed on the scale pan, and the A/D converter converts the analog pressure signal to a digital weight signal. A total weight of the cup filled with water is measured according to the digital weight signal, and a cumulative water intake volume and a water shortage volume of a user. The display screen displays the cumulative water intake volume and the water shortage volume to remind the user to drink water.
