Whether you’re a tech enthusiast or simply someone committed to proactive health management, this DIY project opens a world of possibilities. This is an Internet of Things (IoT) based hence the design would use GSM module to send these reading to the Thingspeak dashboard where it can be remotely monitored globally.
Having a rechargeable backup battery power system, this will also send SMS to predefined person (s) when there is abnormal readings and give out a warning sound at this extreme readings. We will be able to use DIY based sensors like pulse rate sensor to measure pulse, ECG sensor to measure electrocardiograph, heart rate sensor to measure the heart beat. And we can also add a contact type temperature sensor like the stainless steel plated DS18B20 Dallas temperature sensor to measure the body temperature too .

IoT Health Monitoring System: The Schematic Diagram
Explanation of the Circuit Diagram
The pulse sensor enables measurement and reading of heart rate data or pulse rate, a crucial parameter for diagnosing and researching aspects related to human health, anxiety levels, activity, or physical health. The pulse rate sensor is composed of two straightforward optical heart rate sensors with noise reduction and amplification.
The sensor is made up of a photodiode and an infrared light-emitting diode (LED). Infrared light from the LED is transmitted into the fingertip and reflected off the blood inside finger arteries. To determine the current heartbeat rate and display it on the LCD panel, the system uses a heartbeat sensor. The Arduino Nano microcontroller is a component of the transmitting circuit, which is powered by a 5V DC development board and interfaced to an LCD display. Like the sending circuit, the receiving circuit uses an RF receiver and Arduino Nano microcontroller and is also powered by a 5V DC development board.
connecting LCD to the circuit diagram of IoT Health Monitoring System
The receiver circuit includes an LED light and a buzzer, which serve the purpose of alerting the individual responsible for monitoring the patient’s heart rate. Whenever there is a deviation in the patient’s heart rate from the established normal level, both the LED light and the buzzer are triggered for notification. Operators can monitor all patients from a single location while seated. The sensor needs 20 seconds to determine the heart rate value and even in normal circumstances, alerts regarding the patient’s heart rate will be delivered to the medical staff in care of them by SMS and emergency calls which is made possible by the GSM module. BPM means Beat Per Minute.
The Arduino Nano board is the control center of the project design. From the schematic diagram above, the Nano board is connected to the GSM module through serial communication. This type of serial communication is called software serial. It involves using a digital pin on the Nano board that is not the hardware Universal Asynchronous Receiver Transmitter (UART) pins. The receiver (Rx) and the transmitter (Tx) pins are then assigned in the code.
In the given diagram, it can be observed that the Rx pin of the Arduino Nano is linked to the TX pin of the SIM800L GSM module, while the Tx pin of the Arduino Nano is connected to the Rx pin of the SIM800 GSM module. The SIM800 module used here is the EVB breakout board type hence it used the same logic voltage level as the Nano board, 5V. The inclusion of the GSM module is to gain internet access to push the sensor readings to the cloud platform for worldwide tracking and view. It also helped to send emergency alerts like calls and SMS to the health professional in charge of the patient.
The DIY ECG sensor works on 3.3V logic, hence it was connected to the 3.3V rail on the Arduino nano board. The DIY ECG sensor had a LO+ and LO- pins where the digital pin 6 (D6) and the digital pin 5 (D5) were connected respectively. These pins were used to check that the ECG sensors were not reading. The analog output pins on the DIY ECG sensor are connected to analog pin 3 (A3) on the Arduino Nano. This was used to take the analog readings of the heart’s rhythm.
The pulse rate sensor works on both 3.3V and 5V logic voltage, however, to get the best performance out of it; a 5V power rail was used on it. The analog pin of the sensor is connected to analog pin 2 on the Arduino Nano board. This allows for reading the pulse rate of the heart and display it on the screen.
To solve the problem of high pulse rate or low heart rate, a buzzer was added that would instantaneously give an alert by beeping a noisy sound, call the attention of a loved one or that of the medical practitioner to such spikes in heart rate or under normal heart beats. Lastly, since there was no patient with High Blood Pressure (High BP) or Low BP, we had to use a pushbutton to simulate for this extreme cases.
Software Development: The Brain of the Health Monitor System
Setting Up the Thingspeak IoT Dashboard
MathWorks created the Internet of Things (IoT) platform called ThingSpeak. Users of this cloud-based service can gather, examine, and visualize data from IoT devices. The platform provides a storage architecture so that the gathered data may be managed and stored. To organize and categorize data streams from various devices or sources, users can build several channels
Showing the data like ECG readings and Heart rate readings on Thingspeak IoT dashboard
Hence we really only needed the two sensor readings which were the ECG sensor and the heart/pulse rate sensor. This would show us a history of what each sensor was saying each time it was turned on and used. Provided the GSM module has internet access to transmit data to the Thingspeak server.

This DIY project offers not only personalized health monitoring but also opens doors to exciting future possibilities:
Adding more sensors: Track oxygen levels, sleep patterns, or even muscle activity for an even more comprehensive health picture.
Tailored health recommendations: Integrate your system with AI-powered platforms for personalized health advice and preventive measures.
Chronic disease management: Offer invaluable support for individuals managing chronic conditions by providing real-time data and remote monitoring capabilities.
The project design has been successful within the available limits. We have been able to design and program a system that can read and measure body ECG-graphs and heart/pulse rates. Having a rechargeable backup battery power system; we have been able to alert the user of abnormal readings and send both SMS of these to personnel’s phone number as well as teleport real-time readings to Thingspeak IoT dashboard for history and further analysis.

FAQs:
Is it safe to build my own health monitoring system?
While an Arduino-based system can provide valuable health data, it cannot replace professional medical advice. Consult your doctor before relying on your system for critical health decisions.
What skills do I need to build this system?
Basic knowledge of electronics and beginner-level coding skills are sufficient. Online resources and tutorials abound to guide you through the process, even if you’re a complete tech novice.
How much does it cost to build one?
The cost depends on the complexity of your system and the chosen components. Basic systems using essential sensors might cost around $50, while more advanced setups with multiple sensors and communication modules can go up to $150-$200.
What are some potential limitations of using Arduino for health monitoring?
Arduino-based systems are not FDA-approved medical devices and may not be suitable for diagnosing or treating medical conditions. They offer valuable data insights, but always seek professional medical advice for accurate diagnosis and treatment plans.
Can I share my health data with my doctor?
Many systems allow data export to CSV files or integration with healthcare platforms, enabling you to share your data with your doctor for improved diagnosis and treatment optimization.
Do these systems drain a lot of battery power?
The power consumption depends on the chosen hardware and sensor usage. Optimizing sensor readings and using low-power components can significantly improve battery life.
Where can I find resources and tutorials to build my own system?
Numerous online resources offer step-by-step guides, schematics, and code examples for various Arduino-based health monitoring systems. Popular platforms include:
