IOT Based Health Monitor Using Arduino

Monitoring the various parameters of the patient in hospital using the internet of things.Health Monitoring system is based on the internet of things ,the patient data is sends to the cloud server ,stores on the particular channel.

The data on the channel shows in the graph format even the data can be gets on the mobile app and the doctor can be gets it monitoring purpose anywhere in the place,even can alert the doctors signal goes down to particular level of the corresponding patient.

Project Description:

1. Arduino: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. ESP2866:ESP8266 Wifi module is generally used to establish the wireless communication between the devices.But this module is not capable of 5-3v logic shifting and will require an external logic converter.
3. BreadBoard:A Breadboard is used in learning of electronic used in connecting the components,testing it and pieces of bread well as the point holes in the lines to be used
4. HaertBeat Sensor: Heart beat sensor sends the light signal on the finger the blood circulation on the finger is not constant with respect to time sensor uses the infrared lights on the tissue,amplified signal received filtered to monitoring system.
5. Thingspeak: Thingspeak channel is researched based platform used to update the data on the channel and even can be download on the mobile application to monitor the current status of the application via the internet is connected.

Project Implementation:

1. Connect the heart beat sensor has three pins VCC,GND,Signal pin to the arduino board
2. Create a thingspeak channel ,note the WRITE and READ API KEY


3. You need to program for concept of heartbeat as well as update on thingspeak,mention the WRITE API KEY on the program so data will update on the mentioned thingspeak channel
4. Take ESP8266 module connect the VCC,CHD join together connect to 3.3V of the arduino board,connect TX pin to the pin no 1(TX),RX pin to the 0(RX) of the arduino board,connect GND of the ESP8266 to GND of the arduino board,Take male to male connector,connect to GND and RESET of the arduino board.
5. Open the serial monitor ,select the baud rate first 115200 and type as

AT+UART_DEF=9600,8,1,0,0 So the baud rate of ESP8266 is changed to 9600 now

Again the change the baud rate on the serial monitor on the bottom of the IDE software

Type the ATTENTION Commands to connect the wifi or personal Hotspot commands are:

AT-----Press Enter

AT+CWMODE=1-----Press Enter

AT+CWLAP-------Press Enter And now screen shows all wifi or hotspot names

AT+CWJAP=”Name”,”Password”-------type your wifi or hotspot name and password and press enter

After the it shows the it is connected to the internet.

6. Now the program can be upload to arduino board and press reset button on the board one time,program now starts again,open the serial monitor show the wifi connected and the data of the heart beat sensor
7. Open the Thingspeak channel,click on the priciate channel now the heart sensor value is updated as graph.You can get the data on the mobile app,download the virtuino app on the playstore on mobile ,enter the WRITE and READ API key on app ,connect internet the gets the data it update on the screen of the app.
