Abstract

The rapid evolution of wearable health monitoring technology, especially in the domain of calorie counting devices, underscores a notable advancement in integrating sensors with wireless communication for real-time health tracking. This study evaluates the design and performance of an Android-based calorie counting device that combines the MPU6050 accelerometer with the Wemos ESP8266 module. This integration is pivotal for delivering accurate caloric expenditure measurements. Testing revealed that the device operates with a high level of precision, achieving an average voltage measurement accuracy of 97.15%. Specifically, the battery voltage measured at 3.99V DC falls comfortably within the acceptable range of 3.7V DC to 4.2V DC. The TP4056 charger module, Wemos D1 R1 Mini, and MPU6050 accelerometer all maintained consistent voltages of 4.9V DC, aligning with their specified ranges. This consistency in voltage measurements indicates that the device components function within their designed parameters. Additionally, the device’s effective integration with the Blynk app significantly enhances its functionality. Users can input personal details such as age and step length into the app, which then accurately computes and displays the calories burned. This seamless interaction between hardware and software demonstrates the device’s capability to provide real-time health data effectively. Overall, the device exhibits reliable operation and precise performance, validating its design and confirming its successful operation within the anticipated parameters. This advancement contributes to the growing field of wearable technology by offering users a robust tool for health monitoring

Abstract

This study presents the development of a groundbreaking portable spirometer designed to improve respiratory health monitoring by addressing the limitations of traditional, bulky spirometers that are confined to clinical settings. The device leverages the MPX5500DP air pressure sensor and the Atmega328 microcontroller to deliver accurate and sensitive measurements of air pressure changes, which are crucial for assessing lung volume and airflow. The integration of these components enables the spirometer to convert air pressure variations into electrical signals. These signals are processed by the microcontroller and displayed on an LCD screen, providing users with clear and precise lung function data. Rigorous testing and calibration of the spirometer have validated its performance, showing an overall accuracy of 94% for voltage measurements. Functional testing further confirms the device's precision, achieving an impressive 99.14% accuracy for inspiration capacity and 85.51% for expiration capacity. These results underscore the device’s reliability and effectiveness as a significant advancement in respiratory health technology. Its portable and user-friendly design makes it a practical tool for both personal health monitoring and clinical applications. By enhancing the accessibility and ease of respiratory assessments, this spirometer has the potential to improve everyday health management and clinical evaluations, thus representing a substantial leap forward in the field of respiratory health technology.

Abstract

Penelitian alat ukur denyut nadi dengan tampilan OLED berbasis arduino telah dilakukan. Tujuan dari penelitian ini adalah membuat dan menguji alat ukur denyut nadi dengan tampilan OLED berbasis arduino. Penelitian ini dilakukan melalui dua tahapan, yaitu pembuatan dan pengujian alat ukur. Pembuatan alat ukur terdiri dari  pembuatan perangkat keras dan pembuatan perangkat lunak. Pada pembuatan perangkat keras menggunakan beberapa komponen yakni pulse sensor, arduino nano, dan OLED (Organic Light Emitting Diode). Sedangkan pembuatan perangkat lunak yaitu program Arduino IDE. Pengujian alat ukur denyut nadi dilakukan dengan cara membandingkan nilai alat ukur yang telah di buat dengan alat ukur buatan pabrik dengan mengukur denyut nadi dari 10 orang.

Abstract

Peralatan monitoring detak jantung untuk pemantauan secara kontinyu sangat dibutuhkan, misalnya untuk memonitor bayi prematur yang di rawat dalam inkubator. Untuk itu, dalam penelitian ini hasilkan rancang bangun alat pendeteksi detak jantung yang dapat menghitung detak jantung secara kontinyu dan memonitor ketidaknormalan detak jantung secara otomatis. Sistem ini menggunakan pulse sensor sebagai sensor utamanya dan mikrokontroler arduino uno sebagai sistem pengolahan datanya. Sistem ini juga dilengkapi dengan sistem monitoring berupa buzzer yang akan berbunyi ketika detak jantung pasien kurang atau melebihi detak jantung normal. Berdasarkan hasil pengujian, didapat bahwa sistem telah berhasil membaca detak jantung secara otomatis dengan nilai presisi sebesar ±95% jika dibandingkan dengan detak jantung pembanding.

Abstract

This study aims to design Arduino-based scales for weight, height, body mass index. Height and weight measuring device is a measuring tool that functions to measure the height and weight of a person's body. To measure height and weight in general, it is still done separately (separately) in this case the measurements of height and weight are carried out using different tools. By increasing the pace of technological advances, especially in the health sector, according to the author's observations, the height and weight measuring devices are still manual, it's time to increase their function, in this case, it is necessary to increase the function of the tool, especially those related to the field of electronics. The results of measuring weight using CAMRY brand scales with Karya Nesa scales, the average error rate is 0.037 (still within the tolerance threshold), while the results of measuring height are in accordance with the actual. From the results of the Body Mass Index (BMI) analysis with the results of the Body Mass Index (BMI) measurement by Nesa, it is correct and valid (valid). The error rate of weight or scales is relatively small, the accuracy of the scales is very good. The error rate is declared large, if the error is above 5% or greater than 0.05. Based on the results obtained, it is suggested that the scales need to be made precise (not rocking), this can be harmful to the patient and needs to be developed by adding sounds such as: weight, height and BMI results
