The document describes an IoT-based child tracking and safety system. The system uses an Arduino Uno microcontroller along with a GPS sensor and GSM shield to track a child's location via SMS and send alerts if a panic button is pressed. It also connects to the IoT platform ThingSpeak to upload real-time location and heartbeat data. The system aims to provide reliable monitoring of children using both GSM-based communication and GPS tracking.

The Internet of Things refers to the set of devices and systems that stay
interconnected with real-world sensors and actuators to the Internet. The motivation
for this wearable comes from the increasing need of safety for children. This project
focuses on a key aspect any children in danger can be helped by the people around
the child. Most of the wearables available today are focused on providing the
location, activity, etc. of the child to the parents via Wi-Fi and Bluetooth . But Wi- Fi
and Bluetooth seem a very unreliable source to transfer information. Therefore it is
efficient to use SMS as the mode of communication between the parent and child's
wearable device, as this has fewer chances of failing compared to Wi-Fi and
Bluetooth. The platform on which this project will be running on is the Arduino Uno
microcontroller board based on the ATmega328P, and the functions of sending and
receiving SMS, calls and connecting to the internet which is provided by the Arduino
GSM shield using the GSM network. ThingSpeak is an open-source Internet of
Things (IoT) application and API to store and retrieve data from things using the
HTTP protocol over the Internet or via a Local Area

4. Introduction
Network. It is an IoT analytics platform service that allows you to aggregate,
visualize and analyze live data streams in the cloud. ThingSpeak provides instant
visualizations of data posted by your devices to ThingSpeak. With the ability to
execute MATLAB code in ThingSpeak you can perform online analysis and
processing of the data as it comes in. ThingSpeak is often used for prototyping and
proof of concept IoT systems that require analytics. ThingSpeak enables the
creation of sensor logging applications, location tracking applications, and a social
network of things with status updates". Also, additional modules employed which
will provide the current location of the child to the parents via SMS.

The proposed system includes monitoring of the
child's movement to and from school. The info
pertaining to missed child is sent to their
respective parents. Not only the information
about the child's whereabouts but also whether
the child is crying is sent to parents through text
message to their Android mobile device.

15. Specifications
Arduino: is a surface mount breadboard embedded version with integrated USB. It
is the smallest, complete, and breadboard-friendly. It has everything that
Diecimila/Duemilanove has (electrically) with more analog input pins and onboard
+5V AREF jumper. Physically, it is missing power jack. The Nano is automatically
sensing and switch to the higher potential source of power, there is no need for the
power select jumper.
Nanos got the breadboard-ability of the Boarduino and the Mini+USB with a smaller
footprint than either, so users have more breadboard space. Its got a pin layout that
works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power
and ground on the other). This new version 3.0 comes with ATMEGA328 which offer
more programming and data memory space. It is two layers.
GPS NEO-6M: is a complete GPS module that is based on the NEO 6M GPS.
This unit uses the latest technology to give the best possible positioning
information and includes a larger built-in 25 x 25mm active GPS antenna
with a UART TTL socket. A battery is also included so that you can obtain a
GPS lock faster. This is an updated GPS module that can be used with
ardupilot mega v2. This GPS module gives the best possible position
information, allowing for better performance with your Ardupilot or other
Multirotor control platform.
The GPS module has serial TTL output, it has four pins: TX, RX, VCC, and
GND.

16. GSM SIM800C Modem with Antenna Module’s baud rate is configurable from 9600-115200
through AT command. The GSM GPRS Modem is having internal TCP/IP stack to enable you to
connect with the internet via GPRS. It is suitable for SMS, Voice as well as DATA transfer
applications in the M2M interface.
The onboard Regulated Power supply allows you to connect a wide range of unregulated
power supply. Using this modem, you can make audio calls, SMS, Read SMS, attend the
incoming calls and internet, etc through simple AT commands.
The Modem is built with Quad-Band GSM/GPRS engine-SIM800C from SIMCOM, works on
frequencies 850/ 900/ 1800/ 1900 MHz. The Modem is populated with DB9 Female connector
so as to directly connect with computer or other RS232 Compatible devices. MAX3232 from
MAXIM Semiconductor is used for the RS232 Level conversion.
The modem will work with 5-12V DC, which can be fed either through onboard 2 Pin RMC
connector or DC Jack. The modem is powered by a High Current Low Dropout Linear Voltage
regulator so as to withstand high surge current requirement (may rise up to 2A).
