AbstractThis project proposes an automated medicine box tracking, study, and control system. To associate medical healthcare providers with a patient, IoT (Internet of Things) technology is used. A medical kit will be provided to the patient, which will include various sensors, a smart medicine box, and a mobile application. This device tracks the patient's health using temperature, pulse, and oxygen sensors, which are all linked to the ESP 8266 WiFi module. This allows the patient to communicate with the doctor, chemist, and other clinicians. The chain system allows a patient to receive medical attention from anywhere in the world, eliminating the need for the patient to suffer due to the distance and time taken to see a doctor on a regular basis.

    Various biomedical parameters of the patient will be monitored by the doctor from his/her clinic/hospital in this project. During the pandemic, this initiative is useful because we were running out of beds and treatment equipment. Body temperature, heart rate and oxygen level and as well as other parameters are checked. Will be tracked using sensors linked to a node, which will wirelessly transmit the data to the doctor through a mobile app. Using the same mobile app, the doctor can give an e-prescription to the patients as well as a nearby chemist after studying these parameters. The chemists will deliver the necessary medications to the patient's pharmacy box, from which the patient will be able to receive the medication as prescribed (automatic dispensing using servo mechanism). The doctor will receive a report on the medications that the patients have taken at that time.


    Smart Medicine Reminder Box in this paper they have made a smart medicine box that solves medical problems by the RTC module saves the current time, and the EEPROM saves the notification time. As a result, when it's time to take medication, the machine plays a warning sound and illuminates those pillboxes with a bright light. As a result, the patient is aware of the precise number of boxes from which medications must be removed. This project is based on the Arduino-Uno, which makes use of real-time clocks. Since the system detects whether the patient has taken his medicine or not, he cannot postpone his medication. If the patient does not take pills from the box on time, the system will begin to make a noisy noise until the medication is removed from the box. [1]

    "Smart Pill Box Health Care System," this paper combines the principles of an alarm clock with light-based slot sensing on a standard pillbox. It is equipped with a GSM module to warn the patient and the pharmacist at the appropriate time. The system also uses GSM to send a medication warning to the patient via SMS. The system will ask you to "Check the

    alarm time set for all three alarms" after the message has been shown. If yes, then reset the alarm settings; otherwise, set the system's current time. They can choose from three different warning times ranging from 0 to 24 hours. The device also gives the LED indication for specified medicine from the pillbox during the LED indication stage. [2]

    An Internet of Things Approach for Managing Smart Services Provided by Wearable Devices present an autonomous physical condition performance system based on a WSN that allows for the integration of several elements in an Internet of Things scenario, including a smartwatch, a physiological tracking unit, and a smartphone, in this paper. These wearable devices have been linked using Bluetooth, wireless sensor networks, and smart services. The unit collects physiological data from a commercial Bluetooth device. When an unsafe level of any vital parameter (e.g., heart rate) is reached, the user is warned to stop performing the workout. This alarm can be sent to a smartphone or a wearable smartwatch, as well as the emergency services via the ESB if activated. [3]

    Smart Medicine Box has individual compartments that can be filled with medicines and is constructed in such a way that the compartments can be filled with medicines when they are empty. When it's time to take drugs, the medicine box drops the pills and sounds a warning to remind us to take them. To provide the warning, the setup is connected to a servo motor and a GSM module. This involves making a user manual, selecting a larger LCD display, encasing the entire circuitry in a metal or plastic case, and using larger pillboxes.[4]

  3. SCOPE

    This IoT-based medical health care chain system can be used in both hospitals and homes where there is a lack of manpower in a population of patients. This device is helpful and will make the nurse's job easier, in addition to making patients happier to be in the hospital. Healthcare, like other sectors, will eventually change at a fast rate. Since their primary goal is to prevent, diagnose, and cure illnesses, the healthcare industry has remained stagnant in terms of new technologies and discoveries. Patients no longer have to choose between living alone and remaining healthy in the event of amedical emergency due to this IoT-based healthcare chain system. Even if the patient wants to be at home, the continuous monitoring and real-time alerts provided by IoT technology provide a sense of security to patients and their families.

      8. Mobile App

        To monitor the patient from anywhere in the world Blynk Application is used. For the Internet of Things, Blynk was created. It has the ability to control hardware remotely, display sensor data, store and visualize data, and perform a variety of other tasks.

        This platform is made up of three main components:

        1. Blynk Apps:With the help of the Blynk App a Patient- oriented interface is created.

        2. Blynk Server:It is used for all the communication between the doctor and patient.

        3. Blynk Libraries: It provides a hardware platform that allows communication with the server and handles all of the commands that come in.


    The model for an IoT-based Medical Health Care Chain System has been developed. The program has been installed and checked, and it checks the parameters before dispensing the drug in a predetermined amount. Patients that will be tracked on a regular basis will benefit greatly from it.

    To check the accuracy of the results, the parameters of a single patient have been monitored at different intervals and the same parameters were observed for three different patients. The readings are observed on the serial monitor of Arduino IDE and the screenshots are attached below. It is mentioned in tabular form.

The proposed scheme is appropriate for all patients. It effectively keeps track of human condition indicators. It also saves both the doctor and the patient time. If these issues are

diagnosed and addressed in a timely manner, they can be solved to a large extent. Wireless networking advances and wearable sensor technology have paved the way for real-time health tracking systems.

Limitations of the model are:

    • Risk failures:Failure or bugs in the hardware or even power failure can impact the performance of sensors and connected equipment placing healthcare operations at risk. In addition, skipping a scheduled software update may be even more hazardous than skipping a doctor check-up.

    • Security and privacy: Security and privacy remain a major concern deterring users from using IoT technology for medical purposes, as healthcare monitoring solutions have the potential to be breached or hacked. The leak of sensitive information about the patients health and location and meddling with sensor data can have grave consequences, which would counter the benefits of IoT.
