In this Smart Medicine Pill Reminder Project, we are using Arduino board, APR33R3 Voice playback module connected to Amplifier and this connected to Speaker

we have an LCD also to display that,

the main intention before developing this project is to usually remind the medicines which have to be taken in the daily schedule and it is especially useful for old age people, patients, and busy people.

The below Video is the Working condition of the smart medicine pill reminder project.

This is how it reminds the message

Every after 10 seconds it will remind the message. Here we can adjust the Time according to our convenience.

Here Aurdino is giving input to the APR33R3 and this giving input to the Amplifier and amplifier gives the signal to the Speaker.

The output voice message can be visible on the LCD Screen also.

Smart Luggage System IoT Project

Aim:

The main Idea of the Smart Luggage System IoT Project is to develop a luggage that could be user-friendly. The project is more of a luggage less of a robot.

Motivation:

  • Bags have always been an integral part of travel life whether it may be a travel bag or a plastic bag or even leather bag every bag has its own importance and carries different functions and utility.
  • Dragging the luggage all over the place has been done since the golden ages.
  • Thinking of a luggage which conveys its weight, tracks its location, which follows the user automatically or manually, by the touch of the present technology to the old baggage it may bring out its true potential.
  • This has motivated the project all along so that it is user-friendly and could be operated by a Smartphone.

Proposed System:

  • There are a lot of applications to the luggage but all of them are not controlled from the luggage instead the commands are sent from the mobile phone to the luggage via Machine to machine communication.
  • The mobile phone has a pre-installed application software with a pre-installed set of instructions.
  • They wait for the user to send the commands.
  • After the microcontroller embedded inside the luggage receives instruction from the user it acts accordingly. This can either be for tracking its location and send it to the user or send the luggage weight.

Hardware Components:

  • ARDUINO MEGA
  • GPS MODULE
  • ESP8266 Wi-Fi module
  • ULTRASONIC SENSOR HC-SR04
  • MOTOR DRIVER LM298N

Software components:

  1. AURDINO IDE
  2. MIT APP INVENTOR

Working Model:

  1. When Bluetooth is Connected

2) When Wifi  is not Connected

App Screens:

Screenshot of app in Manual Mode

Applications:

  • Painting/Artwork Security:  With a GPS device owners can quickly learn the location of a stolen piece and recover it immediately.
  • Prevention of Car Theft: By installing a tracking device on a vehicle, the location of it can always be known. The vehicle can be easily recovered, but the device will also act as a deterrent for thieves. This will prevent the nightmare of having a car stolen from occurring in the first place.
  • Police & Private Detectives: Police can benefit by attaching tracking devices to baggage during investigations, allowing them to easily track movement and come up with solid evidence.
  • Hiking: With a GPS device, hikers who get lost can be recovered quickly should they ever come up missing

ADVANTAGES:

  • Don’t worry losing your luggage anywhere! It has an onboard GPS module to help you track its position using Google Maps.
  • Whole system integration is controlled through Application installed in Android where controlling the device will get very easy to the user.
  • Weighing the luggage will become easy.
  • The carry of luggage is changed with motorized wheels.

Future Scope:

  • The application should be more dynamic and it should show the live feed of the movement of the luggage which updates every time the luggage is in movement. The tracking could be taken online using the cloud technology.
  • The introduction of Digital Locks into the luggage will help the user secure the contents of the luggage with the help of dynamic encryption algorithms and techniques which will safeguard any Machine to Machine Communication.
  • It comes with GSM module which helps us to triangulate its location when GPS is failed to retrieve the data.
  • Get the status of the flights, regulations using app and pack accordingly.

CONCLUSION:

  • The limitations of the traditional luggage will overcome with Smart Luggage. The market is still new and has potential to accept the new face of luggage.
  • Know the weight of your Luggage at any time and pack accordingly.
  • Move the luggage easily using autonomous and manual modes.
  • The smart luggage will ensure its safety and builds security for its user. From built-in scales to GPS tracking and mobile apps, these bags won’t make hauling stuff any lighter, but they could make the experience less harrowing.

Department Announcement System ECE Project Abstract

Abstract

In most of the institutes, announcements are coming under the major problem. A universal announcement by speakers is mostly deployed in most of the institutes, but there are cases when the announcement needs to be done for a particular classroom or for a particular person.

In that case, such a universal system will not be helpful. One resolution of this problem most of the institutes adopt is deploying one universal system and a separate system for each room and then place people to handle the entire control system.

Though this resolves many issues, it increases the cost of the entire control unit when you have to be dependent on human resources. Automation is one of the most thriving of today’s technology through which many organizations are cutting costs on Human Resources and utilizing human resources in more innovative and productive works.

So here for this issue also we have come up with automating the entire process of announcement where a pre-recorded voice will be played for every announcement in the institutes.
