- There are many low-cost pulse sensors in the market that can be used to make a pulse BPM meter, but when it comes to accuracy and stability, the sensors are not reliable.
- This project describes the design of a very low-cost device which measures the heart rate of the subject and then displays the result.
To develop a heart rate monitoring system using an SEN-11574 pulse sensor and display heart rate value on a web/ mobile application using a HC-05 Bluetooth module.

Hardware:
Components | Quantity |
---|---|
Arduino Uno | 1 |
HC05 Bluetooth Module | 1 |
SEN-11574 Pulse Sensor | 1 |
Breadboard | 1 |
Power Supply | 1 |
Lcd Display | 1 |
Connecting wires | 20 |
Software:
- Arduino IDE
- Arduino Serial Monitor Application
- It is a low-cost project and highly effective.
- One could afford it and implement it easily.
- Due to absence of complex features, the designed device can also be handled by any non-medical professionals. Thus it can also be used at home.
- The pulse sensor SEN-11574 readings can be affected by surrounding noises as it is a relatively open sensor and not an enclosed one. The developed device is not a portable one.
- In future a sensor that is enclosed can be incorporated. The accuracy of the project will improve as the sensor’s readings will not be affected by background noises.
- The user interface can also be improved and made more user friendly.
