Water is essential for maintaining normal physiological functions and overall well-being; however, many school-going children do not consume sufficient water during daily activities, particularly during school hours. Survey findings and reported studies indicate that dehydration among children may lead to reduced concentration, low energy levels, mood changes, and serious health risks such as heatstroke. To address this issue, this project presents the Smart Water Bottle (SWB), an interactive hydration-support system designed to encourage regular water consumption among children. The SWB integrates an Arduino microcontroller, a waterproof ultrasonic sensor, LED indicators, and a buzzer to monitor water levels and provide timely visual and audio reminders. The system activates a green LED when the bottle is full, switches to yellow as the water level decreases, and triggers a red LED with frequent buzzer alerts when refilling is required. Prototype development, sensor calibration, alert programming, and pilot testing were conducted. Results indicate improved hydration frequency, positive user engagement, and increased awareness of healthy hydration habits. The SWB demonstrates strong potential for school-based implementation and commercialization as a low-cost, child-friendly health innovation.
