Smart band for Monitoring Health Service – Node MCU


Internet of Things (IoT) is a new technological paradigm that can connect things from various fields through the Internet. For the IoT connected healthcare applications, the wireless body area network (WBAN) is gaining popularity as wearable devices spring into the market. This paper proposes a wearable sensor node that enables the implementation of an autonomous biomedical monitoring system. Multiple sensor nodes can be deployed on different positions of the body to measure the subject?s body temperature distribution, heartbeat, pulse value, ECG monitoring and BP levels.


Recent years, the number of applications for wearable technologies has grown considerably. Usually, these applications are focused on sensing the human body and continuous monitoring of physiologic and acceleration parameters which are extremely useful in wearable ubiquitous healthcare applications. The existing medical devices used for sensing and monitoring of the human body are invasive, uncomfortable to wear. This paper presents a prototype wearable device which is non-invasive, comfortable, and continuous. This means that patient may not feel the existence of the wearable devices when they are attached on patient?s body


  • The presented service integration approach using a simple message broker enabled a rapid system implementation and proved suitable for creating an integrated telemedicine system.
  • The use of concepts like Enterprise Integration Bus might be a viable option to address this issue and is left for future work.


  • Only message broker was implemented
  • Accuracy of output is less


  • Wireless devices have invaded the medical area with a wide range of capability.
  • To monitor the patient details in a periodic interval is overhead using existing technologies.
  • To overcome this we have changed recent wireless sensor technologies.
  • Added advanced sensors like pulse oximeter for measuring blood SPO2 level


  • Wide range of communication is available
  • Easy connectivity between modules
  • Easy to implement in real time

  • The sensors that are mentioned above in block diagram acts an input device
  • They give live readings to the microcontroller, some sensors are interfaced with ADC then it gives output to the microcontroller
  • Microcontroller receives the readings and upload it to blynk cloud through MQTT protocol
