We designed a pill dispenser which has different container according to the different shapes of the tablets. The dispenser revolves around Arduino microcontroller which controls all the functions of the microcontroller. The time to take the dosage is fed onto the reminder system, this gives a buzzer at the right time. This system also has a talkback voice assist feature which acts as a voice assistant. The count of the tablet and other vital signs like heart beat and blood glucose level are read and stored to the cloud storage. These values can be retrived by the doctors or caretakers using a mobile app. In case of emergency there is also an emergency button provided by the system which sends the users location and alert message to the nearby hospital in order to get immediate assistance

2 Keywords:Pill dispenser, medication dispenser, medical assist, health monitoring, speech medical indication. 1 INTRODUCTION Health recovery process can be improved by using helpful devices that make this process easier. A pills dispenser is such a useful device. In general, elderly or chronically ill persons take many pills for their illnesses. It is very important for healing process or for maintaining health to take medications on time, according to doctor s prescription. If the patient doesn t take medications in the right dose and at the right time, the risks a deterioration of his health. A pill box (also known as pill container or pill organizer) is a container with many compartments for prescribed medication. A pill box compartment can hold several pills of different sizes. There are many types of pill dispensers (including rectangular, cylindrical or pen shapes) [1]. To make it easier to follow we split the system in following elements: Pill dispenser, Pill reminder, Health monitoring Recent research studies on the Internet of Things and smart things domain shows how different elements of human daily activities become increasingly dependent on each other. Smart things are changing human life in the way that nowadays without their applications life is becoming cumbersome. So making use of this in this medication concept will enhance the life of patients, elders and virtually disabled people [2] 2 METHODOLOGY In this project we are going to use Arduino as the microcontroller which controls the overall process of this system. Health monitoring sensors such as heart beat sensor are used. These sensors are non-invasive in nature. The various health parameters measured by these sensors are sent to the micro-controller. The micro-controller is already programmed with the threshold value, this reference value is compared with the measured values. If the values are below the threshold value, we will be able see the health parameters in a mobile application. Incase if it is beyond

3 the level the micro-controller will automatically trigger the GPS and GSM modules such that an alert message is sent to the care taker so that immediate assistance can be provided at appropriate time. The smart pill dispenser has an in-build clock to perform as a pill reminder. The keypad is interfaced with the pill box so that manual operation is also possible. Meanwhile the name of the pill will be read out by the talk back option, even the health parameters is also read out for the blind and elderly people. The IR sensor is placed in such a way that it counts the number of pills that is been dispensed. With the stored data in the cloud, the doctor will be able to assist the patient health. Even self-health monitoring is possible in such case, which helps in creating an awareness. A mobile app is designed specially, for real time monitoring of heartbeat level. A cloud server is created or an existing cloud like things speak can be used in order to save the data s measured by the prototype in the cloud. This will be useful for the doctors and care taker to keep track of it. The main aim of this whole prototype and the app is to take the prescribed pills at the right time without missing the dosage prescribed and to keep track of the health parameters regularly. 3 BLOCK DIAGRAM

4 4 DESIGN AND IMPLEMENTATION The design of a pill dispensing system that is affordable to people in low incom countries, takes cognizance of first principles and the viability of local materials. The architecture of the pill dispensing system is shown in Figure 1. It is based on the following design principles: Simplicity, which enhances upgradability and maintainability; Affordability, which is a crucial characteristic of any system that has the potential of high utility in low-income environments; Flexibility, a characteristic that enables the system to adapt to new user requirements through the addition of new functionalities and system characteristics. 5 USE CASE 6 PILL DISPENSER MODULE We proposed a programmable pills dispenser. This device can release the medication at certain time intervals, This device offers an easily used service, which reminds through an buzzer. At a simple pressing of a button, the desired medication is obtained, at the prescribed hours or prescribed time intervals. The pills are stored in their appropriate containers and the count of the pills

5 are obtained by the sensors which sends the tablet count value to the cloud [2]. The motor driver IC (L298N) which is connected to the Arduino microcontroller controls the rotation of the motors in the pill box which regulates the dispensing of pills on keypress. Another important feature of the pill dispenser is that it has a talk back feature. This will be very much useful for the virtually disabled people. 7 PILL REMINDER MODULE The Pill Reminder module is used to indicate the users to take the pills as per the time set in it. DS1307 is the frequently used real time clock (RTC) IC for clock and calendar. The clock function provides seconds, minutes and hours while the calendar function provides day, date, month and year values. The increment button must be pressed must be pressed to change the hours. As the clock is in 24 hour format, the hours will be incremented between 0 and 23. Once the hours of the alarm is set, we must press the next button to go to minutes tab. Again increment button is pressed to change the minutes. Once the alarm time is entered, set button is pressed and the alarm is set. 8 HEALTH MONITORING Health monitoring plays a vital role in providing the vital information such as heart beat value etc.to the patients. In this project we have used the heartbeat sensor [5,6]. These two sensors are connected to the Arduino microcontroller

6 Fig 1 PULSE RATE SENSOR Fig 2 GSM GPS MODULE In case of pulse detector, a pulse oximeter sensor is placed on the finger. The sensor id designed to provide a digital pulse rate of the user. While in the working condition the beat LED flashes in unison with the pulse rate. The digital output is connected to the arduino board to give the number of Beats Per Second (BPS). The pulse sensor works on the principle of light modulation by blood flow through finger at each pulse. Global Positioning System

7 (GPS) is utilized to locate the patient [7, 8]. The latitude and longitude estimation obtained is transmitted to the doctors phone along with the current status of the patient using Global System for Mobile (GSM) Communication [9]. 9 EXPERIMENTAL RESULTS The system was tested under various working conditions. Initially the pills are first loaded onto the desired containers. The reminder is also set manually or can be preprogrammed as per the dosage prescribed. The patient is provided with a keypad using which they can obtain the different type of tablet. As soon as the tablet gets dispensed a text to speech module will start to respond to the patient and reads out the tablets name, this will act as a voice assistant. Finally the pill count, heart beat value and glucose level values are stored onto a cloud server. In case of emergency the system is provided with two buttons. The first button acts in such a way that in case of any critical condition it is triggered and it will send an alert message which contains the user s location to the nearby hospital to ensure immediate medical assistance. The second button is used if there s a shortage in tablet, this button can be pressed manually to send a message to the pharmacy. Fig 3: ThingSpeak cloud server for IOT

8 Fig 4: Heart Beat values visualization using thing speak In Fig 3, Thing Speak is used as a cloud server since it is an open source. Which enables the user to store the data from various sensor in the cloud with no cost. In this cloud server we will be able to view the data at the same time visualization of the data is also possible. In Fig 4, The heart beat is measured using the sensor, those data are sent to the things speak cloud server. As said earlier the heart beat can be visualized using graphical representation. Fig 5:Heart Beat Values for sensor

9 Fig 6: Regular pill count updates from ESP8266 In Fig 5, values of the heart beat which is obtained from the heart beat sensor. The accurate values of the counts are obtained and displayed in the console window for viewing. In Fig 6, the graphical representation of the data from ESP8266, which is said to be the NODEMCU, WIFI module The tracking of pill count will also give the clear idea about the pills that is taken by the patient and home alone people. It will be the real time tracking of the intake of pills. This visualization of pill can be done with various fields in x and y labels respectively

11 In Fig 7, the setup designed for dispensing of pills appropriately. It consists of two pill box which is of various size will dispense pills of two different sizes. In this design process it is very important to note the mechanism of the pill box. It is capable of dispensing only one pill at a time Fig 8, is the RTC setup which is responsible for pill reminder part and also have a facility to set an alarm at desired time. It consists of the real time clock module, which on programming it with Arduino for the desired date and time. Fig 9: Alert message to the mobile Fig10: Graphical representation of the sensor values

12 Fig11:vdata at particular point of time In Fig 9, once the heartbeat of the patient exceeds the threshold level, an alert message is triggered from the GSM module along with the location of the patient to the care taker and nearby hospital. This method will be very useful in case of emergency. Fig 10, The other results are graphical representation in cloud server. 10 CONCLUSION An affordable medication dispenser, which can function with both direct and indirect (rechargeable batteries) power sources, can dispense more than one type of prescription medication at once, and is programmable in patients local languages or language of choice (e.g. English), will not only assist in patients adherence to medication, but will increase adherence in different age groups and economic backgrounds,with further development this systems can be made to be used in all households at an average economical price. Especially this type of product in countries with more population like India can enhance the life of the people at an affordable price. 11 ACKNOWLEDGEMENT This project has been funded by IEEE Madras Section under Project funding Scheme
