Abstract

Dehydration in kids can pose a significant health hazard, especially when it occurs amid situations such as while they are attending kindergarten or schools and their supervisors cannot supervise them all the time. This project presents the development of Smart Water Tracking System using an ESP32-based system integrated with a load sensor (HX711) to measure realtime water intake. The data is collected and store to Firebase cloud storage when internet connectivity is available, else it will store the data locally for offline use. The purpose of this storing technique is to ensure the accurate and continuous data collection in IoT applications. A user-friendly monitoring application that involving JavaScript, HTML and CSS to allows parents and caregivers to visualize daily, weekly and monthly drinking patterns, with features such as real-time hydration tracking and refill detection. By combining offline data synchronization and cloud services, the system provides a reliable tool to encourage better hydration habits in children and lessens the risk of dehydration that may pose threats within the education sector, with a solution at low cost which enables custom form factor.
