GPS-based Child Tracker with Emergency Text Alerts IoT Project

The hectic life of parents makes it very difficult to personally look after the kids. To overcome the problem of personal monitoring of children, we have come up with the idea of a GPS-based tracker with text alerts when the child is not present in the specified region.

Problem Statement:

To solve the problem of difficulty in keeping a check on children while they are playing in open areas while letting the children have their freedom to play from constantly being mocked by parents and to monitor the whereabouts of children by working parents. There is a similar project on Women Security System that can be seen here

Project Working Process:

Hardware Components

  • Arduino UNO
  • GPS Module
  • GSM/GPRS Module 

Software’s Used

  • Arduino IDE
  • Android (MIT App Inventor)

In this context, the solution we propose is a GPS-based Child Tracker with Emergency Text Alerts android application that can help parents in tracking the presence of their children. This application works with the help of android mobile-enabled with the ‘SMS’ feature and ‘Global-Positioning System (GPS)’ on the GSM network.

This Child Tracker with Emergency Notifier application works in two ways, the first is GPS-based is related to Location services, and the second is SMS-based which is related to Network services. In case when the Location-based services not working then the application alternatively use Network-based services that can send and receive messages.

The GSM and GPS module is connected to Arduino Uno. The GSM module has a sim (data) through which we can receive message alerts and the GPS helps to track the location.

The data is sent to the cloud from GSM using AT commands and HTTP. The cloud is connected to the mobile app and the data is displayed in the app installed on the parent’s mobile.

Automatic Vehicle Accident Alert System using IBM Cloud

In this Automatic Vehicle Accident Alert System project, we are using Node MCU, Arduino UNO, Accelerometer, and GPS module to store the location of the vehicle and to send an immediate alert message to the nearby hospitals, police stations…etc. Here we use serial communication to send the information from Arduino to Node MCU.

The Arduino receives the latitude and longitude values of the vehicle from the GPS module. The accelerometer reads the XYZ axis values. These values are read by Arduino. The XYZ values are compared with the condition given in the code to check whether the vehicle is met with an accident or not.

If the vehicle is met with an accident, latitude, and longitude values are copied to the NodeMCU, and the message is sent to the nearby police stations, and hospitals using the msg91 application. The GPS location of the vehicle is continuously stored in the IBM cloud.

A Smart & Secure Helmet IoT Project

Abstract

This Smart & Secure Helmet IoT Project is aimed at using the concept of the Internet of Things (IoT) and chemistry with the rider’s helmet to provide extensive safety, guidance, and health care features. The following features are planned to be implemented in a phase-wise manner in the project :

1. Internet of Things(IoT) based traffic emergency system

2. Internet of Things(IoT) based traffic guidance system

3. Extensive protection from sunstrokes

4. GPS tracking

All these facilities are to be implemented on the helmet with maximum cost efficiency to make the final product within the reach of the Indian common man.

Goal

The goal of this project is :

  • To provide advanced traffic safety mechanisms through IoT to the people at affordable costs.
  • To provide IoT-based traffic guidance system to the people – first target: Tier-1 cities in India
  • To provide extensive protection from sun strokes, especially during the hot summer season in India
  • To make this project an innovative platform for many other applications like Easy GPS tracking, Health sensor, etc.

Motivation

There has been a multiple-fold rise in the number of road accidents in recent days and many times, emergency services have faced difficulty in a timely response to the situation.

In large cities, sometimes the emergency services find it difficult to locate the spot of the accident based on a phone call.

Companies(logistics, customer service) face difficulties in tracking the vehicles of their employees

Even with the heavy risk of not wearing a helmet, People do it as they find it inconvenient to wear a helmet in hot humid sub-Continent conditions. Our new chemical system compartment in the helmet solves it.

All these situations prompted us to look into the possibility of IoT coming up helping people in these cases and we found out that in the initial phases of our project, we can use the helmets used by people while driving. Later the same technology can be used on other vehicles to provide an all-around extensive safety mechanism.

Class Diagram:

ADVANTAGES

The helmet will be mounted with appropriate sensors at appropriate positions on the helmet. They are calibrated to sense high impact due to an accident or crash.

Once they detect the designated input, the rider’s location is immediately sent to a cloud of hospitals, and the nearest hospital is notified about that so that the ambulance can reach the spot immediately.

1. Immediate response to any accident by the emergency services since all of them become a part of the network (of things).

2. The location of the accident is too updated to the emergency services so that finding the location won’t be much trouble.

3. Details of the personnel are also updated to the emergency service center so that formalities of paperwork may be completed beforehand.

4. Continues tracking of employees for Companies like logistics, customer service, etc.

5. Proper Traffic Guidance using Google Services.

6. Humidity reduction inside Helmet.

7. Many inbuilt Bluetooth facilities like automatic call acceptance (while driving) etc.

Conclave on the Internet of Things provided us with exposure to the applications of the concept of the Internet of Things (IoT) and several other creative approaches that solve day-to-day problems by invoking the interconnection and sharing between the day-to-day products.

Apart from the conclave, we would like to appreciate the suggestions and help from the faculties which proved to be a priceless booster to our project.

We are a team dedicated to the research and development of creative solutions to day-to-day problems. We aim at creating smart, simple, innovative ad cost-effective solutions which could be affordable for the common man of India.

Future Work

PROTOTYPE-II: To implement a traffic guidance system using Google services.

PROTOTYPE-III: To implement a fully integrated traffic safety and guidance system

Smart Traffic Light Control System Embedded Systems Project

Abstract

Considering the heavy traffic congestion on daily basis sometimes emergency vehicles like ambulances get stuck in the congestion which complicates the situation. Normal traffic lights are not able to operate according to the requirement of emergency vehicles. So, our project aims to make them operate keeping the track of the emergency.

Design/Algorithm

We are operating the traffic light based on the interruption given by the emergency vehicle. So when it gets interrupted by an ambulance it turns off all the traffic signals apart from the one on which the ambulance is coming.
Proposed- In the Smart Traffic Light Control System project IR transmitter is being used which will transmit the code and the receiver will detect it then the microcontroller(Arduino) will get an interrupt and it will stop the normal functioning of the traffic signal and free the path of the ambulance by making the light green.
CCN components to be applied-
Source encoding and Decoding and error detection like checksum and parity Checker.

Design Schematic/Flow Diagram/Block Diagram

Components Used (S/w, H/w)

Hardware components:

• IR module
• Arduino
• Breadboard
• LEDs, Resistors
• Jumper and connecting wires

Software Used:

• Arduino(IDE)

Cost Estimation:

Around 250 if we use a general microcontroller instead of Arduino.

Work Done

Whenever there is no emergency vehicle like an ambulance, the traffic system will work as usual but when the vehicle comes it will turn on the green light (according to the program) so the ambulance will not have to wait.
For making it foolproof, source encoding and error detection are done by assigning a specific code to the ambulance.

Working Constraints

  • The traffic congestion needs to happen for deploying this technique.
  • Only aiming at VIP/Ambulance vehicles.
  • Works using IR so restricted to a particular radius.
  • Only applicable to Tier-1 cities with traffic lights already installed.

Future Scope of Project

  • In the future, this project can be implemented for every vehicle irrespective of the priority.
  • IR can be replaced by GPS modules to increase the effectiveness and span of the connection.
  • It can be used as a tracking device by the company to seek their employee’s current positions, like pizza delivery or e-kart suppliers, etc.
  • By using the tracking sensor we can implement our traffic cloud system to help users to navigate through the less clumsy path.

Cloud-enabled Vehicle Theft and Accident Detection System Project

For vehicle theft, in this project for the opening of the door we first click on the button, after a few seconds we get an OTP (random number) generated by Arduino through the GSM module to the phone number stored in the Arduino, we again text back the same random number.

After some time the OTP will be checked, if it’s correct the door will be opened, in our Vehicle Theft and Accident Detection System project the servo motor rotates, if it’s wrong the buzzer will ring indicating someone is opening or stealing the vehicle

A mobile phone is also used for the owner’s interaction with the device installed in the vehicle, so that, when the owner wants to track the vehicle, only he/she can do it.

PROPOSED WORK

In this Cloud-enabled Vehicle Theft and Accident Detection System Project work, we use the accelerometer to detect the position on different axis (to detect the toppling condition) of the vehicle during an accident. The output of the accelerometer acts as an input to the microcontroller present on the board. The GSM & GPS module fitted onto the device computes the latitude and longitude value for the vehicle. The time, latitude, and longitude values are recorded periodically. The sensor value is transmitted to the cloud in the event of an occurrence of an accident.

A continuous application runs in the background and recursively compares each vehicle’s sensor field to some standard value. A deviation from the standard value retrieves the address of the location from the last updated longitude and latitude via the API.

The occurrence of an accident is promptly reported to nearby hospitals and the police through the messaging service. With the GSM and GPS module installed in the device, the location of the car can be tracked in real-time, which helps the police to recover a stolen car.
