Introduction

In today's era of rapidly developing communication technology, modern tools have made it easier for us to monitor various objects and get accurate data. One of the most essential aspects of human health is the measurement of height and weight. Traditional methods such as manual measurements using gauges such as meters and scales have several weaknesses, especially in terms of long measurement time. Therefore, an innovative tool is made, which can measure height and weight as well as processing the data using an Android-based application. This tool not only gives rapid measurement results, but also calculates a person's ideal weight value using the body's mass index method (BMI).

What is the Body's Mass Index (BMI)?

The body's mass index (BMI) is a method introduced by the World Health Organization (WHO) to determine the status of a person's weight. With the simple formula of IMT (kg / m²) = body weight (kg) / (height (m) ²), we can easily find out whether someone has the ideal weight, less, or more. BMI is a very popular indicator and is often used in health research to assess the risk of diseases related to body weight. Understanding BMI is crucial in maintaining a healthy lifestyle, as it helps individuals to identify their weight status and take necessary actions to achieve a healthy weight.

Innovation in a Gauge

By using the Arduino Uno microcontroller, this height and weight gauge can take measurements automatically and send data that has been collected to the Android application. This allows users to get the information needed without the need to handle measuring instruments manually. This system also provides a better user experience by providing data that can be accessed anytime and anywhere. The integration of Arduino Uno microcontroller and Android application has revolutionized the way we measure height and weight, making it more efficient, accurate, and convenient.

The Advantages of This Measuring System

  1. Time Efficiency: Measurement can be done in a very short time. The automation process reduces the time needed to measure height and weight compared to the manual method. With this system, users can save time and effort, as the measurements are taken automatically and quickly.
  2. Data Accuracy: With proper programming and accurate use of sensors, the measurement produced is more precise and reliable. The accuracy of the measurements is crucial in maintaining a healthy lifestyle, as it helps individuals to track their weight status and make informed decisions about their diet and exercise.
  3. Easy Data Processing: Data collected can be managed and processed using an Android application, so users can easily find out their ideal weight status. The Android application provides a user-friendly interface, making it easy for users to access and manage their health data.
  4. Accessibility: By connected to an Android device, users can access and store their health data more practically. The accessibility of the system is a significant advantage, as it allows users to access their health data anywhere and anytime.

The Working Principle of the System

The system consists of an Arduino Uno microcontroller, a weight sensor, and a height sensor. The weight sensor measures the weight of the individual, while the height sensor measures the height. The data collected from the sensors is then sent to the Android application, where it is processed and displayed to the user. The system uses a simple and efficient algorithm, which calculates the BMI and provides the user with their ideal weight status.

Conclusion

The combination of making a height and weight gauge with the calculation of ideal body weight using the IMT method has been proven successful and provides many benefits. Not only facilitates measurements, but also helps people to better maintain their health by knowing their weight status appropriately. This innovation shows how technology can make a positive contribution to human health and well-being, and it is expected that more sophisticated tools can support health monitoring in a more efficient and accurate way.

Future Scope

The system can be further improved by adding more features, such as:

  • Integration with wearable devices: The system can be integrated with wearable devices, such as smartwatches and fitness trackers, to provide users with a more comprehensive view of their health.
  • Machine learning algorithms: The system can use machine learning algorithms to analyze the data collected and provide users with personalized recommendations for improving their health.
  • Cloud-based storage: The system can store the data collected in a cloud-based storage, allowing users to access their health data from anywhere and at any time.
