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.
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:
- Arduino UNO
- GPS Module
- GSM/GPRS Module
- 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 the 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 the 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.
Useful Projects on Self Security in Emergency Situations:
The GPS-based Child Tracker with Emergency Text Alerts app is integrated with maps and geo-fence.
The GPS is connected to Arduino using a VCC pin, GND pin, RX pin, and TX pin. Connections: VCC to 3V3, GND to GND, RX to TX, and TX to RX respectively. GSM is connected to Arduino using VCC, GND, RX, and TX pins. Connections: VCC to 5V, GND to GND, pin 3 to TX, pin 4 to RX respectively.
A tiny GPS++ library is included. Using IBM cloud (node-red flow editor) the data is sent to a mobile app developed using MIT app inventor.
