ALAT PENGUKUR TINGGI & BERAT BADAN | OTOMATIS HITUNG BMI | ARDUINO LOADCELL | TECHNOPRENEUR PROJECT

Summary

In this video, Indra Septian Adi introduces a digital weighing scale and height measurement device that also calculates BMI (Body Mass Index). The video demonstrates how the tool works, showing step-by-step instructions on building the controller and assembling the components, such as an ultrasonic sensor for measuring height and an LCD for displaying the results. Indra also explains how the device indicates weight status through color-coded LCDs: green for normal, yellow for underweight, and red for overweight. The video concludes with a look inside the device's setup, featuring an Arduino Uno and simple wiring.

Takeaways

• 😀 The speaker introduces a digital weighing scale and height measurement tool that calculates both weight and height, and provides a BMI reading.
• 😀 The tool integrates both height and weight measurements to calculate Body Mass Index (BMI) to evaluate how normal one's weight is relative to their height.
• 😀 The video promises a step-by-step guide on how the controller for this digital tool is created and set up.
• 😀 The speaker encourages viewers to like, comment, and subscribe at the beginning of the video.
• 😀 A significant part of the video features the speaker showcasing how the system works, including the display of weight, height, and BMI readings.
• 😀 The BMI readings are categorized by color-coded LCD indicators: red for overweight, yellow for normal, and green for underweight.
• 😀 The speaker uses an ultrasonic sensor (HC-SR04) to measure height, which is part of the digital measuring system.
• 😀 The system uses a 20x4 LCD display to show readings for height, weight, and BMI, ensuring clarity in the measurements.
• 😀 The device is built using an Arduino Uno and includes a step-down power supply to manage the system’s power requirements.
• 😀 The speaker reveals the simplicity of the internal system, which includes the Arduino Uno and an RJ45 cable for easy connection, aimed at simplifying the setup for users.
• 😀 In the demonstration, the speaker shows how the device reads a user's height (160 cm) and weight (65 kg), calculating the BMI to indicate obesity, thus suggesting a need for a diet.

Q & A

What is the main topic of the video?

The video focuses on the creation and functionality of a digital scale and height measurement tool that also calculates BMI (Body Mass Index).

What does the digital scale measure?

The digital scale measures both height and weight, and calculates the Body Mass Index (BMI) based on these measurements.

How does the tool calculate BMI?

The tool uses the user's height and weight to calculate BMI, which helps determine if a person’s weight is normal, overweight, or underweight based on their height.

What components are used in the digital scale and height measurement tool?

The main components used are an ultrasonic sensor (HC-SR04) for measuring height, an LCD display for showing the results, and a load cell for measuring weight.

What does the color coding on the LCD display represent?

The LCD display shows color coding to indicate the user’s weight status: green for normal weight, yellow for underweight, and red for overweight.

What is the maximum weight capacity of the load cell?

The load cell used in the project has a maximum weight capacity of 150 kg, which is sufficient for measuring the weight of an average adult.

What does the term 'BMI not found' indicate?

'BMI not found' appears on the LCD display when no weight is detected by the scale, meaning the user has not yet stepped on it.

What is the purpose of using an RJ45 and LAN cable in the setup?

The RJ45 and LAN cables are used for easy connection of components, ensuring a reliable and straightforward assembly of the system.

How does the user interact with the tool?

The user simply steps on the scale, and the tool automatically measures their height and weight, then displays the results along with the BMI and the corresponding color on the LCD.

What does the presenter show at the end of the video?

At the end of the video, the presenter demonstrates how the digital scale works, including revealing the internal components of the device, such as the Arduino Uno and the step-down power converter.
