Intelligent Water Cup Based on STM32

Water cups are essential for our everyday life. But for ordinary water cups, people can't know the water temperature and water volume in the cup, and they can't know exactly whether they drink enough water every day. Also, they can't be reminded to drink water when they are busy. Therefore, this paper designs a multi-functional intelligent water cup system based on STM32, which aims to make people develop good drinking habits. In this system, the microcontroller can control the temperature sensor and the pressure sensor to measure water temperature and water volume in real time. The water temperature error does not exceed ±0.5°C. The user can set the water temperature and drinking time in advance on the LCD by touching the key to remind the user to drink water by a voice module. Also, by means of Bluetooth module, the user can obtain information such as water temperature and water volume through the mobile phone APP. The lithium battery built into the cup can power the microcontroller and each module. This system can successfully realize the function after debugging, and can well solve people's drinking water problem. Compared with the ordinary water cup, the system has high cost performance and has broad prospects.
