Health Care Monitoring System
The new outbreak of Coronavirus poses a major threat and has been declared a global public health emergency. Whole World is trying to stop the virus but no efficient tool and strategy is there to control it. Monitoring of Patient’s health remotely is really important, especially for patients suffering from a long-term disease. Health care monitoring system nowadays require instant sensing, precision predictions and immediate response with medication which contains sensing modules to measure parameters like temperature of the body, beat rate of heart, sweat rate and transfer it to the computer so that the health condition of a patient can be analysed remotely. Thus, it reduces the doctor’s workload and also gives accurate results. Further this system uses GSM technology which enables the monitoring of all parameters on the mobile phone. The inputs are analysed through a micro controller platform from the patient and any abnormality felt by the patient causes the monitoring system to send a message to the respected caretaker. These are the essential data for the future analysis and review of a patient’s health condition.
The main purpose of this health care monitoring system project is to make a health monitoring system where one can check pulse rate, and body temperature, and even monitor their health condition. This system also provides a fall alert. Body pulse can be checked with the help of a pulse sensor. Body temperature can be checked with the temperature sensor. If there is any fall detected, the buzzer will be activated, and a message will be sent to the caretaker.
“Health” is the state of physical, mental, and social well-being. By taking good care of the body, one can be fit and healthy, as there is a saying that a healthy mind resides only in a healthy body. As we grow, we become older, and as we grow older, we are more prone to chronic diseases. Health care monitoring system have rapidly evolved recently, and smart systems have been proposed to monitor patient current health conditions, in our proposed and implemented system, we focus on monitoring the patient’s blood pressure, and his body temperature. Based on last decade statistics of medical records, death rates due to hypertensive heart disease, shows that the blood pressure is a crucial risk factor for atherosclerosis and ischemic heart diseases; thus, preventive measures should be taken against high blood pressure which provide the ability to track, trace and save patient’s life at appropriate time is an essential need for mankind. In the existing system, one had to consult the doctor for a periodic health checkup. As this is a time consuming and very tiring process one would neglect the periodic health checkup, but in the proposed system, there is no need to consult the doctor. One can check and monitor his/her basic parameters with this system. This system can be made more efficient with the technology arising. As it is said that prevention is better than cure, one can monitor his/her health. This system is more efficient, cost-effective, and economical compared with the existing system.
- Arduino Uno : Arduino Uno is a microcontroller from the Arduino Family. It was developed by Arduino. cc and is based on the Microchip ATmega328P microcontroller. Uno has 20 I/O pins, of which 6 are analog and 14 are digital pins.

- Pulse sensor (MAX30205): It is used to check the pulse of a person.
- Temperature sensor: temperature sensor is used to check the temperature of the body/environment.
- GSM module: global system for mobile communication (GSM) module is used to send and receive data/messages.
- LCD: LCD (Liquid Crystal Display) is a type of flat panel display used to print values.
- Accelerometer sensor(ADXL345): It is used to detect the motion of a body.
- Buzzer: An Audio Signalling Device. Buzzers can be mechanical, electromechanical, or piezoelectric. It produces an alarming sound when triggered. Used in various applications like Game buzzers, Alarm Buzzers, Trains, etc.
- Arduino Ide : Arduino IDE (Integrated development environment) is software that is used to dump the program into boards. Arduino- IDE’s major use is to build electronics-related projects. Arduino is an open-source platform simple and easy-to-understand platform for coding.
HOW TO INSTALL ARDUINO IDE CLICK ON THE LINK :
In the following block diagram pulse sensor, accelerometer sensor and temperature sensor are the input devices. GSM module, LCD, and buzzer are the output devices. Arduino Uno is the microcontroller
First temperature and pulse values are measured. If the temperature is more than the required temperature, if the pulse rate is less than the required pulse rate then a buzzer will be activated and a message will be sent to the user through the GSM module.

The SDA pin of the ADXL345 is connected to the A4 pin of the Arduino. The SCL pin of the ADXL345 is connected to the A5 pin of the Arduino. The 3V3 pin of the ADXL345 is connected to the 3.3V pin of the Arduino. The GND pin of the ADXL345 is connected to the GND pin of the Arduino.
The red wire of the temperature sensor is connected to the 9th pin of the Arduino. The black wire of the temperature sensor is connected to the 10th pin of the Arduino. The yellow wire of the temperature sensor is connected to the 11th pin of the Arduino.
The red wire of the pulse sensor is connected to the 13th pin of the Arduino. The black wire of the pulse sensor is connected to the GND pin of the Arduino. The yellow wire of the pulse sensor is connected to the 12th pin of the Arduino.
The VCC pin of the GSM module is connected to the 5v pin of the Arduino. The TX pin of the GSM module is connected to the RX pin of the Arduino. The RX pin of the GSM module is connected to the TX pin of the Arduino. The GND pin of the GSM module is connected to the GND pin of the Arduino.
Pin1 of the potentiometer is connected to 5v of the Arduino. Pin2 of the potentiometer is connected to the LCD VEE pin of the LCD. pin3 is connected to the GND of the Arduino.
Note: make sure to take proper precautions while connecting the components.
The data taken by the temperature sensor and pulse sensor are first converted to electrical signals and sent analog data to the controller. Output devices like the GSM module and buzzer act upon the data given by the output devices and give an alert to the guardian or consultant doctor if any abnormal signals are detected by the sensors.
Hence, the health care monitoring system is successfully built using the GSM module. It allows patient health analysis quickly. In the future, we can replace the Arduino with raspberry pie which increases the health monitoring parameters in detail.
