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.

Block Diagram:


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.

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.


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.

Accident identification based alerting location over GSM and GPS Project

This proposed project work is an attempt to design an advanced vehicle security and tracking system that can identify vehicle accident detection and sends the location details using GPS and GSM.

In present existing models many vehicles do not have accident detection system they have to wait for someone help to inform our guardians, this is a very big problem in 4 wheelers so to over all these we have developed a prototype model which has accident detection system in from in front and back side of the vehicle when they get pressed that indicates accident detected.

In this Accident identification based alerting location over GSM and GPS project we have used Arduino UNO open-source motherboard to which we have interfaced accident detection switch GSM modem SIM 800L for sending the message when accident detected, and GPS is for getting the location accident place, and in this accident identification project we have used an airbag which will get open when an accident is detected and the vehicle gets stopped automatically.

The safety of the vehicle This complete system is designed taking into consideration the low range vehicles to provide them with extreme security.

Vehicle Security System with Engine Locking and Alerting Project


This system is an attempt to develop an advanced vehicle security system that can identify vehicle theft and can track the details using GPS and GSM modules.

In present existing security systems strangers can enter the vehicle and take it without starting the engine, the vehicle owner will not be able to identify when the stranger doesn’t start the vehicle, if stranger removes the battery connections then entire security system will be an off state. It is very difficult to identify the vehicle in this situation.

Here we are proposing the new security system for 4 wheelers, which will have given security to the vehicle.

In this model vehicle will have RFID reader inside the car beside driver seat once after you enter the vehicle you have to keep the RFID tag in RFID reader for clearing the security check, if the RFID tag is matched then vehicle ignition will be on else alert signal will be sent to car owner along with location with help of GPS and GSM. (GPS for location identification and GSM for message sending) and the car will make emergency sound with a buzzer, engine ignition and fuel pump will get off with help of a relay.

If any stranger tries to open the door we have sensors like sound which will detect the sound like when a stranger breaks glass or hit with hammer etc… we have bump sensors in the bumper of the vehicle which will notify when cars meet an accident.

GSM and GPS based Smart File Security System


The main aim of this Smart File Security System project is to design and development of a certificate folder tracking system. The tracking devices are GSM and GPS modules. The GSM and GPS tracking system are one of the modern accurate tracking devices. Our design comprises with the Arduino MC that controls whole the system.

These devices are used to locate the particular location of the objects such as lost certificate folder, identification of lost keys and send their coordinates to the user through an SMS. GSM digitizes and compresses the data, then sends the data to a channel in its own time slot. It operates at 1800 MHz frequency band. GPS receiver collects the information to calculate the user’s exact location.

The tracking devices are used to locate particular objects using GPS (Global Positioning System).The design consists of GSM and GPS system to track the location of the object. By arranging this tracking device in the objects like folders, briefcase etc. the user could track their location from time to time. This makes the user find his belongings within less time.

The design is done in such a way that the system could be arranged in less space and accurate in tracking locations. As there is a GSM slot in the design, the user could get coordinates of the object from time to time through SMS. The design consists of an alert system to find an object by the sound.

The size of the microcontroller can be decreased, and it can be arranged in the small objects. As this project is based on a microcontroller, GSM, and GPS. This project is developed with low cost by integrating GSM and GPS.

The system consists of different modules which are linked wirelessly with GSM modules. Cost effective SMS service of GSM network is used for transfer of data between the modules. This service provides the information about the location of the place, of the certificate folder.

Working operation of project

In this project we are using Arduino nano as microcontroller unit for reading and sending the data, We have GPS NEO 6M for getting the current location of module and this is interfaced to Arduino nano to pin 2 and pin 3, GPS NEO 6M will send the serial data in NEMA format to Arduino nano, and Arduino nano will take longitude and altitude values, whenever the GSM modem receives the message it is sent to Arduino nano and this will send the GPS location to sender (file owner).

GSM modem will be connected to Arduino nano to pin 0 and pin 1 RX and TX, Arduino nano and GSM SIM 800 and Arduino nano will communicate each other with AT Commands, GSM modem will have SIM card. We have small piezoelectric buzzer integrated into the file for easy identification of file with the sound indication.


• Certificate files.
• Property document files
• Other Important log data files etc…


This project is very useful as compared to existing file folders system which can track the file with small SMS with help of GPS system. This project can be further modified to IOT for more easy access with android application.
