2 Related Technical and Theoretical Support
2.1 Introduction of Intelligent Device Technology
The sensing technologies used in smart devices mainly include sensors, cameras and sound sensors, which can monitor the user's drinking water in real time. The sensor can detect the water level in the glass to learn how much water the user has already drunk; the camera can capture the user's drinking action, analyze the frequency and quantity of water; the sound sensor can monitor whether the user is drinking and determine the user's drinking behavior based on the sound feedback.
Through the combination of these sensing technologies, the intelligent device can more accurately record the water and remind users to replenish water in time. At the same time, the intelligent device can also make a reasonable drinking water plan and provide scientific drinking water suggestions. The application of these sensing technologies makes intelligent devices a powerful health manager, effectively helping teenagers to maintain healthy drinking habits.
In addition to sensing technology, intelligent devices also combine advanced technologies such as data analysis and artificial intelligence to provide users with their drinking habits and health conditions through the analysis of users' more personalized and accurate health management services. In the future, with the continuous progress and improvement of intelligent technology, the healthy drinking water reminder device will certainly become a good helper for teenagers in a healthy life.
2.2 Drinking Water Volume Monitoring Principle
When designing a healthy water reminder, the first need to identify the daily water needs of teenagers [2]. According to expert advice, teenagers should drink a percentage of their body weight. Normally, the daily water intake for adolescents can be calculated using the following formula:

The amount of water required per kilogram of body weight can be based on the age and sex of the adolescent. In general, adolescents need 30-30-40 ml [3]. The specific value can be adjusted according to the actual situation. Through this formula, we can calculate the daily amount of water needed for each adolescent, thus providing a reference for the design of a healthy drinking water reminder device.

Through the comprehensive consideration of functional requirements and design points, we will design a healthy drinking water reminder device that meets the needs of users, to provide reliable and intelligent drinking water management auxiliary device for teenagers.
3.2 System Structure
3.2.1 Sensor Module
The sensor module is one of the key components of the healthy drinking water reminder, which can monitor the user's drinking water in real time and transmit data to the control module. Through this module, the reminder device can accurately judge whether the user has drunk enough water, so as to timely send out sound and light signal for reminder.
The functions of the sensor module mainly include detecting the water level in the water cup, monitoring the drinking frequency of the user and analyzing the user's drinking habits. Through the real-time collection and analysis of these data, the reminder device can intelligently provide users with personalized drinking water reminder service to help them develop good drinking habits.
The importance of the sensor modules is self-evident. It can not only allow users to know their drinking water, but also help users to establish the correct concept of drinking water, to ensure their health. Especially for the adolescent group, they are often busy with their study and life, easy to ignore their own drinking water problems. The sensor module of the healthy drinking water reminder device can effectively solve this problem, allowing teenagers to develop good drinking habits and improve their quality of life [5].
In general, the sensor module is the core component of the healthy drinking water reminder device, and its role is indispensable. Through the effective use of this module, the healthy drinking water reminder device can better serve the users and achieve the goal of healthy drinking water.
3.2.2 Reminder Method
In order to ensure that the daily drinking water volume of teenagers reaches the standard, the healthy drinking water reminder device helps users develop good drinking habits through a variety of reminders. The choice of reminder is a key link, it needs to consider the user's habits, preferences and actual situation. For example, users can be reminded to drink water by prompting sound, vibration, or flashing lights. It can also be combined with a smartphone App to let users know their drinking water at any time by pushing messages or setting regular reminders.
In addition to the above mentioned reminders, the healthy drinking water reminder device can also customize and personalized reminder services according to the user's personal habits and needs. For example, set the drinking water target for different time periods, and intelligently adjust the drinking water amount according to the user's daily activities and temperature changes. Through continuous optimization and improvement, the healthy drinking water reminder device can better help teenagers to develop good drinking habits and ensure their health. In the future, with the continuous development of science and technology, the healthy drinking water reminder device will become an indispensable intelligent device for teenagers to escort their health [6].
4 Experiments and Results Analysis
4.1 Experimental Design
In the experiment, we designed a healthy water reminder device designed to help adolescents ensure that their daily water intake meets the recommended standards. The smart device can automatically calculate the amount of water needed every day according to the user's weight, activity level and temperature, and help the user to drink water [7] on time through the reminder function.
To verify the effectiveness of this healthy water reminder, we recruited a group of volunteers to participate in a week-long experiment. Volunteers used a reminder device to record daily water intake and compared to another group of volunteers who did not. We collected the daily drinking water data of each volunteer during the experiment and conducted statistical analysis.
In the experiment, we first conducted a detailed weight and activity level survey for all volunteers to determine the amount of water they needed each day, [8]. Then, they were divided into two groups, one using a healthy water reminder and the other group not. During the experiment, we would send reminder messages to the volunteers daily, reminding them to drink water and record their water intake data.
4.2 Data Collection and Analysis
We conducted data collection through laboratory control variables, and used a variety of scientific methods for data analysis. We set different drinking water reminder frequencies to observe the teenagers' drinking water. We compared the amount of water consumed in the experimental and control groups to evaluate the effect of healthy drinking water reminder on the drinking habits of adolescents.
Experimental data were collected to recording water intake and frequency for each participant through the healthy water reminder itself and the smartphone app. We collated and analyzed the collected data using statistics and reached some important conclusions. For example, healthy water reminders can effectively increase drinking water in adolescents, especially in exercise or hot weather. Through data analysis, we also found that the setting frequency and method of the reminder device have a significant impact on the reminder effect, and different reminder strategies may need to be developed for different individuals.
Overall, we verified the effectiveness of healthy drinking water alerts in helping adolescents establish healthy drinking habits through the collection and analysis of experimental data. This not only provides us with scientific basis, but also provides an important reference for the development and optimization of healthy water reminder in the future [9].
