Smart water bottle system workflow integrates ESP32 microcontroller with water level and temperature sensors to track hydration in real time. The system monitors sensor data, processes consumption metrics, and transmits readings via Wi-Fi or Bluetooth to a mobile application for display and storage. Users receive intelligent hydration reminders based on consumption patterns, creating a closed-loop feedback system that encourages healthy drinking habits. Fork this diagram on Diagrams.so to customize sensor types, add cloud backend integration, or adapt the workflow for other beverage containers. This architecture demonstrates practical IoT sensor fusion and mobile app connectivity for consumer health devices.
