Dehydration is a common and serious condition that affects millions of people globally, despite increasing access to clean drinking water. Staying hydrated is one of the most important habits for maintaining overall health and energy levels but sadly, due to higher levels of business among people. It is often overlooked. This causes health issues like fatigueness, headaces and etc [1].Dehydration is linked to various health issues, including heat-related illnesses, kidney diseases, and even death. Studies show that 75% of Americans are chronically dehydrated, with elderly populations being at higher risk. Addressing this, our project proposes a solution to ensure optimal hydration: a smart water bottle, Smartflask, integrated with sensors and an application to monitor and encourage regular water consumption. The Smartflask app allows users to set daily hydration goals, and through its combination of a distance sensor placed at the bottle’s cap and real-time notifications, it tracks the user’s water intake and sends reminders when needed. This smart system ensures that users meet their hydration targets consistently. Several challenges were addressed during the development, including selecting a suitable microcontroller (Particle Boron), ensuring sensor accuracy, and designing a user-friendly interface. The results of our experiments show that the ToF distance sensor is accurate in measuring water levels and that the smart water bottle's performance can be enhanced by optimizing power consumption and sensor integration. This project showcases the potential of smart technology to significantly improve hydration habits and overall health.
