Introduction

Measurement is a crucial activity in our daily lives, and it plays a significant role in various sectors, including the beverage, agriculture, and household industries. However, manual measurement using devices such as measuring cups has its limitations, including inaccuracies due to subjective factors. To overcome these limitations, technology has provided solutions by creating automatic and digital measuring devices. One example is the Automatic Uno-based water volume gauge that uses an ultrasonic sensor, such as the HCSR-04. In this article, we will discuss how to calculate the automatic water volume using the Arduino Uno-based HCSR sensor.

Understanding the Automatic Water Volume Gauge

The Automatic Uno-based water volume gauge is a tool that uses ultrasonic sensors to detect and measure the water level in a container. This water level is an indicator of how much water is present in the container. With a simple formula, the volume of water can be calculated as follows:

Water Volume Formula

Water volume = water height x water container area

This formula is the basis for calculating the volume of water in the container. The water height is measured by the ultrasonic sensor, and the water container area is a constant value that depends on the size of the container.

How the Automatic Water Volume Gauge Works

The Automatic Uno-based water volume gauge works by using the ultrasonic sensor to measure the distance between the sensor and the water surface. This distance is then converted into a water height value, which is used to calculate the volume of water in the container. The results are displayed on an LCD screen, making it easier for users to know the volume of existing water without having to look visually.

Additional Analysis and Explanation

Automatic System Strengths

The Automatic Uno-based water volume gauge offers various advantages over manual measurement methods. First, measurement accuracy can increase significantly, reducing errors due to human inaccuracies. In addition, this tool also facilitates the measurement process, as users no longer need to make observations directly. The results displayed on the LCD provide convenience in reading data, so that users can immediately know the volume of water without having to stop for a moment to see the results of manual measurements.

Components Used

In this project, the main components used are Arduino Uno and ultrasonic sensors, such as the HCSR-04. Arduino Uno functions as the brain of this system, which processes data obtained from ultrasonic sensors. The ultrasonic sensor has the ability to measure distance by utilizing sound waves, so that it can be used to determine the water level accurately. In addition, LCD functions as an output display that makes it easy for users to read measurement results.

Application in Everyday Life

This technology has many practical applications in daily life, such as in the beverage, agriculture, or even in the household industry. For example, in the beverage industry, the use of this tool can help in filling the container precisely, thereby reducing waste. In the agricultural sector, farmers can monitor the volume of water in irrigation more efficiently. While at home, this tool can help in controlling the use of water, which is increasingly relevant to the issue of sustainability of water resources.

Conclusion

With the use of developing technology, the Automatic Uno-based water volume gauge offers convenience, accuracy, and efficiency in the measurement process. This not only improves the quality of measurement but also supports better water resource management in various sectors. Along with technological advances, it is expected that more innovations can be produced to improve the quality of life of the community.
