Child Safety Wearable Device
Abstract
This paper discusses the concept of a smart wearable device for little children. The major
advantage of this wearable over other wearable is that it can be used in any cellphone and doesn't
necessarily require an expensive smartphone and not a very tech savvy individual to operate. The
purpose of this device is to help parents locate their children with ease. At the moment there are
many wearables in the market which help track the daily activity of children and also help find
the child using Wi-Fi and Bluetooth services present on the device. But Wi-Fi and Bluetooth
appear to be an unreliable medium of communication between the parent and child. Therefore,
the focus of this paper is to have an SMS text enabled communication medium between the
child's wearable and the parent as the environment for GSM mobile communication is almost
present everywhere. The parent can send a text with specific keywords such as "LOCATION"
"TEMPERA TURE" "UV" "SOS" "BUZZ", etc., the wearable device will reply back with a text
containing the real time accurate location of the child which upon tapping will provide directions
to the child's location on google maps app and will also provide the surrounding temperature,
UV radiation index so that the parents can keep track if the temperature or UV radiation is not
suitable for the child.
Existing System Proposed System
Working principle:
An ATmega microcontroller controls the system architecture of the wearable with an
Arduino Uno boot- loader. A 5 pin header allows for power (+3 V) and ground connections as
well as providing access to TX, RX, and reset pins of the ATMega328p. The Fig illustrates the
architecture of the child safety wearable device, which depicts the various technologies and
technological standards used. such as the GPS module upon being triggered by the Arduino
GSM shield. The GSM shield is used as an interface to send the data received by the Arduino
Uno via SMS or MMS to a smartphone over GSM/GPRS. The GSM shield functions as a trigger
for the Arduino Uno to request data from its various modules. If an SMS text with distinct
characters is sent to request the current location or GPS coordinates is sent to the Arduino GSM
shield via the user's smartphone, then the GSM shield triggers the Arduino Uno to request the
current GPS coordinates. Depend on the command we can receive the data’s of the system like
we want to know about temperature reading ,we send the message of particular ward.
