Oct 13, 2025 by wbrum.org 34 views

Introduction

Coffee is one of the most widely consumed beverages globally, and Indonesia is one of the largest producers of coffee. However, the quality of coffee beans can be affected by various factors, including water content and mass. In this article, we will discuss the development of a water and mass measuring tool in Arduino Uno-based coffee beans using soil moisture sensors and load cell sensors.

The Importance of Water and Mass Measurement in Coffee Beans

Coffee beans have different water content and mass, which can affect their quality. Low water content in coffee beans can improve their quality, while high water content can reduce quality and require re-processing. Therefore, accurate measurement of water content and mass is crucial for coffee farmers to produce high-quality coffee beans.

Design and Implementation of the Measuring Tool

The measuring tool is designed to measure the mass of coffee beans using a load cell sensor and display the measurement data on an LCD screen using the HX711 module. The load cell sensor is connected to the ATmega328, which functions as the controller of the entire circuit. After measuring the mass of coffee beans, the next step is to measure the water content using a soil humidity sensor. This sensor is modified to detect water content in coffee beans, and the measurement results are displayed directly on the LCD.

Benefits and Analysis of Measuring Devices

The measuring instrument has several benefits for coffee farmers. Firstly, the measurement of water content helps farmers determine whether the coffee beans are ready to be harvested or need to be further processed. The right water content is essential to maintain the quality of coffee and avoid damage during storage. Secondly, the measurement of the mass of coffee beans helps farmers manage their crops, maximizing profits.

From a technological perspective, the use of Arduino Uno as the main controller offers flexibility and ease of programming. Farmers do not need to have a strong technical background to operate this tool, making it easier for them to use modern technology to improve agricultural products.

Soil Moisture Sensors: A Key Component in Measuring Water Content

Soil moisture sensors are commonly used to measure humidity in the soil. However, in this project, the sensor is modified to detect water content in coffee beans. The sensor measures the electrical conductivity of the coffee beans, which is directly related to the water content. The measurement results are then displayed on the LCD screen, providing farmers with accurate information about the water content of their coffee beans.

Load Cell Sensors: Accurate Measurement of Mass

Load cell sensors are used to measure the mass of coffee beans. The sensor consists of a strain gauge that measures the deformation of the coffee beans under a known load. The measurement data is then transmitted to the ATmega328, which calculates the mass of the coffee beans. The measurement results are displayed on the LCD screen, providing farmers with accurate information about the mass of their coffee beans.

Conclusion

The water and mass measuring tool in Arduino Uno-based coffee beans using soil moisture sensors and load cell sensors is a game-changer for coffee farmers in Indonesia. By utilizing this technology, farmers can more easily choose quality coffee beans and increase their productivity. In addition, this tool can also be the first step to implement more efficient and effective modern agricultural technology. Through the use of this tool, it is hoped that the quality of Indonesian coffee can continue to increase, which in turn will have a positive impact on the economy of coffee farmers and the coffee industry as a whole.
