Internet of Things (IoT)- based remote health monitoring systems have an enormous potential of becoming an integral part of the future medical system. In particular, these systems can play life-saving roles for treating or monitoring patients with critical health issues. The main aim of the project is to build a Node MCU based safety device for covid-19 safety rules to reduce the disease spread. We focus on most common indoor measurement system to allow the people.   The temperature sensor measures person’s temperature using sensor. The persons pass one by one. In case that person’s temperature exceeds average human body, and then Node MCU generates signal to lock the door and gives the audible alert through buzzer.   The main aim of the project is to build health monitoring system using IOT and Blynk app. The project makes a use of digital Blood Pressure sensor, LM35 temperature sensor, LCD display, Buzzer and NodeMCU module. The main controlling device of the project is NodeMCU module which is interfaced with input and output modules and it has inbuilt wi-fi which is used to upload the sensor data into the Blynk app and sending the alert notification into the Blynk app in abnormal conditions.          

Features:  

• Design a real-time health monitoring system using different sensor.
• Using IOT technology to upload data into the Blynk app so user can access this data from anywhere in the world.
• If the sensor data exceed threshold value the system give the Auto alarm and also sending the notification into the Blynk app.

         

The major building blocks of this project are:  

1. Regulated power supply with voltage regulator.
2. Node MCU.
3. LED indicator.
4. Temperature sensor
5. Digital Blood Pressure sensor
6. LCD display.
7. Buzzer.

           

Software’s used:  

1. Arduino IDE for compiling and dumping code into Microcontroller
2. Express SCH for Circuit design.
