Story

Introduction

E-Nursing is transforming healthcare by integrating advanced technologies to enhance patient care, data management, and remote monitoring. A critical component of digital nursing involves leveraging connected medical devices to track patient vitals in real time. In this project, we aim to utilize a conventional blood pressure monitor, paired with the ESP8266 (WeMos) microcontroller, to facilitate real-time data sharing.

The ESP8266 will read the blood pressure data via an appropriate interface and transmit it over Wi-Fi to a secure online server. Healthcare professionals can then access this data remotely to monitor patients, enabling timely interventions, improved management of chronic conditions such as hypertension, and seamless communication between patients and care teams.

By using the ESP8266’s Wi-Fi capabilities, this solution ensures flexibility and eliminates the need for additional wired connections, making it ideal for home healthcare applications and remote patient monitoring. This project emphasizes the role of cost-effective IoT solutions in promoting a more efficient and data-driven healthcare system.

In this project I have 1 blood presure monitor conventional, I wan to make connected with internet and can send data to website, so nurse / doctor can monitoring realtime patient.

Prepare Hardware

First open Blood presure monitor, and make sure this blood pressure have serial output

and then solder 3 wire (red for VBat, yellow for rx, and black for GND),

Prepare Software

Use arduino IDE to program wemos esp8266, and firs step check communication wemos with Blood Pressure Monitor

after upload test the Blood Pressure monitor

data result same with serial monitor. so next step integrated with database

Prepare Database and website

With phpmyadmin, make a database and field data to storage data from user

and make front end to display data with php language

Final code, upload arduino esp to connect internet and if success read data, save to database and show in front end

and last data save in database and show in front end

Conclusion

This project leverages the ESP8266 (WeMos) microcontroller to transform a conventional blood pressure monitor into a connected device capable of uploading systolic, diastolic, and BPM measurements to an online database. By consistently saving user data after each measurement, this system provides healthcare professionals with real-time access to vital health information.

With the ability to monitor patients remotely, doctors can track trends, identify potential health risks early, and make timely interventions. This project underscores the potential of IoT technology in enhancing healthcare delivery, improving chronic disease management, and fostering better communication between patients and doctors for a healthier, more connected future.
