Introduction

Blood pressure is a crucial indicator of one's health, and measuring it accurately is essential for maintaining overall well-being. Traditionally, analog or digital tensimeters have been used to measure blood pressure, but with the advancement of technology, a new innovation has emerged: digital tensimeters integrated with Android smartphones. This article discusses the design and development of a digital tensimeter that utilizes the ATmega328 Microcontroller, MPX5050DP sensor, and Bluetooth HC-05 to display measurement results in real-time on Android applications.

Digital Tensimeter Action Mechanism

The digital tensimeter works by utilizing the MPX5050DP pressure sensor, which converts pressure into voltage. This voltage is then processed by the ATmega328 microcontroller, which has an ADC (analog-to-digital converter) that converts analog data from the sensor to digital data that can be processed by the microcontroller. The data from the results of blood pressure measurements are displayed on the 2x16 LCD screen and sent to an Android smartphone via Bluetooth HC-05.

Use of MPX5050DP Sensors and Pulse Sensor

The MPX5050DP sensor is the heart of this digital tensimeter, capable of detecting high-precision blood pressure. The data captured by the sensor is then converted to an analog signal and processed by the microcontroller. In addition to the MPX5050DP sensor, there is also a pulse sensor that functions as an indicator of pulse. Recording of blood pressure values is carried out when the pulse pulse signal reaches its peak.

Advantages of Digital Tensimeter Based on Android

Android-based digital tensimeters have several advantages over analog or digital tensimeters, including:

Graph Display

Measurement results are displayed in graphical form, making it easier to understand and interpret. This makes it easier for users to see the trend of blood pressure and know the changes that occur.

Data Access

Data on blood pressure measurements stored in the Android application can be accessed at any time. Users can track blood pressure history and divide the data with medical personnel for health monitoring purposes.

Ease of Use

Digital tensimeters based on Android are easy to use and more practical because they do not require additional tools such as a stethoscope.

Portability

This digital tensimeter can be used anywhere because it is integrated with an Android smartphone.

Challenges and Conclusions

Design and development of Android-based digital tensimeters is an effort to develop practical and efficient medical devices. However, there are several challenges in its development, such as:
