Wearable Child Tracker





Complete step by step instructions: http://www.instructables.com/id/Wearable-Child-Tracker/
Are you worried of your kids getting lost when you are out at a crowded place? That's obvious, isn't it? This project will reduce the risk of children getting lost at unknown and crowded places thus will also eleminate your nightmares. As you may have already guessed from the name, this project is basically a child tracker that can give you the exact GPS location through an SMS to your phone when required.
This project uses the Mediatek Linkit ONE as a base for communication between your phone and the tracker and to get the GPS location. As linkit one has in-built GSM and GPS features, you don't need to connect any external shield or modules which makes it a perfect weekend project to be completed within an hour. You just need a SIM card with some balance or an SMS pack. The best part is that the device will work in any part of this world provided that there is a mobile network available at that place.
The project is enclosed in a digital camera pouch thus can be tied around the waist along with a belt, can be kept in your child's bagpack or pocket. Since the project has GPS, you can not only use it as a child tracker but also as car tracking or bagpack anti-theft device.

How it Works?


The process is very simple. As you may already know, linkit one as in-built GPS and GSM features. So when you send a message to linkit one through your phone, it is received by the SIM card present on linkit one and transferred to the board thereafter.
The board then processes the signal, gets GPS data by directly connecting to a sattelite and then sends this data to the no. which is mentioned in it's code. The data when entered on Google Maps gives you the exact GPS location of the device. As the device will be with your child, it will tell you the location of your child so that you can easily reach that place.
It shall be noted that you will only get the data till the device is on. Unavailability of power supply or the battery running low will not give you the GPS data.
