IoT Based Patient Health Monitoring System using ESP32 Web Server

....................................................................................................................................................................................................................................

In this project, we will make IoT Based Patient Health Monitoring System & Monitor the Health Status of Patient on ESP32 Web Server.

We will use the MAX30100/102 Pulse Oximeter sensor to measure the Heart Rate/Pulse(BPM) as well as the Blood Oxygen Level(SpO2). We will use a DS18B20 Temperature Sensor to measure the temperature of the body. Similarly Patient needs to be placed in a room with a certain temperature and humidity level so that he doesn’t feel uncomfortable. In order to do that we need to monitor the room temperature and humidity as well. So we will be using DHT11 Humidity & Temperature Sensor.

After Interfacing we will connect the ESP32 to the Internet and using Local Server like local IP Address you can monitor the Patient Body Temperature, Pulse Rate, and Blood Oxygen level. The ESP32 Web Server will hold the sensor data and can be retrieved every time after refreshing.

The following are the components required for making this project. All the components can be purchased from Amazon. The components purchased link is given below.

1. ESP32 Board
2. MAX30100/MAX30102 Pulse Oximeter
3. DS18B20 Temperature Sensor
4. DHT11 Sensor
5. 4.7K Resistor

sir I'm a Biomedical Engineer and currently working in a private hospital, this will surely help monitor out patient wirelessly wor without contact with covid 19, it will lessen also the exposure of our frontliners.

[creativeelectronicchannel]

I make this project but not showing pulse max30100 sensor values how to rectify that problem

[adalarasu]

Wonderful video...
Awesome explanation...
Greetings to you to reach heights...
I like your efforts 💯👏👏👏

[RGPinger]

next time use Intel 8 core CPU for connecting 3 sensors. This can handle attiny.. or ESP8266-01.

[mcjovendeluna]

what simulator software did you use for the circuit diagram and connections?

[reginaaprilia]

Hello sir i wanna ask to you, i use max30100 and ds18b20 with nodemcu but the result of max30100 is zero, when i compile max30100 only the result is right. Why when i combine with ds18b20 the result is zero sir?

[pink_panther]

Hi, can we buy this whole product being assembled and programmed? If possible, please let me know asap. Thank you!

[anantkushagra]

Amazing work sir, but not getting the readings of spo2 showing 0 only

[Akash-hczs]

sir can u tell me how to make circuit diagram. means which software ur using to make circuit diagram. please tell me sir....

[celinelim]

Can anyone help me? I connected as the video shown but only temperature sensor shows value, but the MAX30100 keep showing 0 as the result. I try the oximeter separately, it can run but when I add in the temperature sensor, the reading of oximeter will not be shown. Any solution?

[curlytales]

Room temperature and humidity is not showing..
Also If I connect the DS18B20 sensor and pulse oximeter is not showing the data parallel..If I connect one, the other one is not working..
Kindly help resolve this issue

[truptipatil]

Sir I tried this project but the pulse oximeter and body temperature sensor are not working at the same time. Please help me

[ghalibatiya]

Is it posdible to add blood presure sensor to the device and how?

[pietervansambeeck]

can you please explain how you create the icons in the web page, I don't know anything about creating web pages, but I want to reuse some part of your code for an other project with different icons.
this project is very nice, I also created one for myself.
keep going on, as I like to learn more.

[juanangeldragon]

Thanks for sharing your valuable knowledge friend, I have a question if I wanted to integrate an image in the local server, what options do I have, should I add an SD reader?

[SanthoshKumar-lnor]

What is the use humidity sensor and what purpose to measure a room temperature plz tell

[saahilwrites]

Sir I want to do exactly same work but without connecting the sensors directly with the Arduino or esp32.
Like wanna make sensors wearable for the patient so he don't need to go to sensors by himself everytime.
Your response will be highly appreciated!

[willifountain]

which is the webserver library used ?
please respond

[reginaaprilia]

Hello, I have a problem, I put a resistor pulling 4.7k on the scl and sda, but the result is zero, can you help me? And sometimes the LED lights on the max30100 don't light up, what is it?
