Electrical mini projects with circuit diagrams
Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. Modern embedded systems are often based on microcontrollers i. In either case, the processor s used may be types ranging from general purpose to those specialized in a certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor DSP.

In this tutorial we are going to design and construct an IoT based patient health monitoring system using Arduino and generic ESP What is IoT patient based health monitoring system? IoT based patient health monitoring system is a generic term given to any medical equipment that has internet capability and can measure one or more health data of a patient who is connected to the device such as heartbeat, body temperature, blood pressure, ECG, steps etc. By this definition, it includes devices such as smart-watches, fitness trackers, smart-phones to expensive hospital equipment which can connect to internet.
IoT based health monitoring system is used where the patient and heath expert s are at different locations. Based on the received data the heath expert can prescribe a best treatment or take an immediate action in case of an emergency. The proposed design of IoT based heath monitoring system is built around Arduino microcontroller which is the brain of the project.
Arduino collects real time health data from pulse sensor which measures heartbeat in minutes or BPM beats per minute. A digital temperature sensor connected to Arduino measures body temperature of the patient.
Abnormal heartbeats can be detected by just listening to the beeps. This is useful for a healthcare professional who is actively monitoring a patient on site. How to set-up Thingspeak account to receive patient data:. Circuit diagram of IoT based patient health monitoring system:.
Circuit description:. As mentioned earlier Arduino is the brain of the project and you may use any Arduino board that is available with you and you can connect to the same pin numbers that are shown in the schematic. The arduino is responsible for collecting, displaying and sending the data to ESP It does not come with a USB port so we need to use its UART pins to upload a code which will be discussed in the later part of this post.
It operates at 3. ESP will connect to its designated server which is programmed to it and passes the data. A microcontroller like Arduino can be programmed to calculate its analog output to BPM or beats per minute. It can operate from 3. On the front we have a green LED with a specific wavelength and a light sensor; you can place your finger except thumb on front part of the sensor with a slight pressure. The process behind detecting heartbeat is when our heart pumps there will be blood flow in our nerves, this flow changes the light intensity reflected to the light sensor.
On the back of the pulse sensor there is an amplifier and noise reduction circuit which outputs analog signal proportional to the changes in the reflected light.
The pulse senor must be used with dry fingers and the back of the sensor must not be touched and since ambient light can interfere with the sensor while measuring, it is recommended to wrap your finger and the sensor with an insulation tape as shown below for the best result:. We are using a general purpose water proof digital temperature sensor DS18B20 to measure body heat which comes in a sealed metallic enclosure.
We are using a water proof sensor because the sensor will be placed on human body for prolong amount of time and dust, sweat and other body fluids can accumulate on the sensor which could lead to inaccurate temperature measurement. Where the temperature sensor can be place on human body? There are several places on human body where temperature sensor can be placed like: oral, ear, underarm, rectal etc. Our best recommendation is underarm for the sensor placement after considering accuracy and convenience.
You need to place it for at-least 2 minutes so that temperature gets settled properly. A LCD display is provided to see the real time data from the sensors; it is set to show the body temperature and heartbeat in BPM. A 10K potentiometer is provided using which you can adjust LCD contrast for optimum legibility. Audio beeps can give a healthcare professional an insight about pulse of a patient, for example, slow pulse indicates that the patient is sleeping or in coma or fast beep indicates that the patient is in some health trouble and need immediate medical attention.
Please note that not all medical devices in hospitals beep is indication of heartbeat, it can be of several types of alerts ranging from not so important alerts to extreme emergency alerts. How to upload code to generic ESP?
Select the latest version and click install. Installation could take about 5 minutes. ESP code upload circuit diagram:. Download Thingspeak. Program code for generic ESP You need to insert your Wi-Fi credentials here:. You need to insert channel details here:.
Program code for Arduino:. You need to upload the below given code to Arduino once you successfully uploaded the ESP code. So, yes this project uses two set of program codes to function. Result: Private view on Thingspeak. It could take more than 30 seconds to update a field and each field will be updated one after the other. In the above list of connected devices to Wi-Fi router we can see that ESP has been connected successfully. If you have any questions regarding this project feel free to ask us in the comment, you will get a guaranteed reply from us.
My nick name is blogthor , I am a professional electronics engineer specialized in Embedded System. I am a experienced programmer and electronics hardware developer. I am the founder of this website , I am also a hobbyist, DIYer and a constant learner. I love to solve your technical queries via comment section. I wanted the list of components you have used in this , because no were this is present please send it as soon as possible. We will update it, but it could take some time.
In the mean time, please take a printout of the circuit diagram and give it to the shopkeeper where you are purchasing the components and mark a tick beside the component when you get them. I tried to build the project, following the steps mentioned. However, the lcd screen just displays a dashed line. Need some help.. I am sorry, it is not possible for us to do presently, but there is enough information to build the project successfully in the post.
You will know what to do next once you start building. Hi, I wish I could send you the project, we are also running out of components in lockdown. Can you provide me with the details? Hi can you give me a little guidance about what shall I do if I want to use another type of data storing except Things peak? Hi, In this project the code is specifically written for Thingspeak, if you want to use a different IoT platform then you need to follow their procedure.
Your email address will not be published. Skip to content. We will see: What is IoT based health monitoring system? Block diagram of IoT health monitoring system.
How to setup Thingspeak account? Circuit diagram of IoT health monitoring system. How to upload code to ESP correctly? Program code for ESP and Arduino. Prototype, result and troubleshooting. Block diagram: Block diagram — IoT based patient health monitoring system.
Channel Setting. API Key. Generic ESP Pulse Sensor- Heartbeat. DS18B20 Water proof temperature sensor. Uploading code to ESP IoT based patient health monitoring system. Please check the wiring associated with LCD connections…..
How can Can I program my esp without using reset or flash button? Can you make a video on building this project from showing every wire connection and steps. A video on the hardware components connection would be much more helpful.
