Nowadays, smart water cups on the market have the function of displaying temperature and reminding people to drink water. Personally, I think I can buy it. Smart water cups use temperature-measuring thermistors, which can sensitively reflect the current water temperature, and are definitely better than ordinary water cups. Products made by Shi Heng Electronics are applied to it. If you pay more attention to health, you can buy a smart water cup to remind yourself to drink more water.
