This document describes a proposed child safety wearable device that uses SMS communication to allow parents to locate their children. The device would include a GSM module to send SMS location data, a GPS sensor to detect location, temperature, UV and SOS light sensors, and an alarm buzzer. It aims to help parents easily locate children in crowded areas by sending an SMS to get the child's location, temperature, or activate an alarm. The device provides real-time monitoring of a child's surroundings while being low-cost and using widely available SMS technology.

3. OBJECTIVE
• The main objective is to help parents to
locate their child in a easy manner.

4. INTRODUCTION
• The motivation for this topic comes
from the increasing need for the safety
of little children getting lost in the major
crowded areas.

5. EXISTING SYSTEM
• There are many wearable devices which are used to locate the children only
through WIFI and Bluetooth.
• This system is very unreliable source to transfer information.

6. PROPOSED SYSTEM
• To overcome the drawback of existing system this is implemented using SMS as the
mode of communication.
• In this the parent send the SMS to know the location of the child.

7. OVERVIEW

8. CIRCUIT DIAGRAM

9. GSM MODULE
• GSM is a standard developed by the ETSI to describe protocols for second
generation digital cellular network used by phones.
• GSM modem can accept any GSM network operator SIM card and act just like a
mobile phone with its own unique number.

10. SOS LIGHT
• SOS stands for Survival Signal Light.
• SOS is known for the sign of help.
• It is used to simplify and standardize communications.
• The purpose of this light is to able to alert the people nearby that the child might be
in distress since the light will be flashing.

11. GPS LOCATION SENSOR
• The location sensor object is used to communicate with the global positioning
satellite receiver in phone.
• When the location sensor communicates with the built in GPS receiver it can
determine the location of your device.

12. TEMPARATURE SENSOR
• This give an output proportional to temperature.
• Most temperature sensors are positive coefficient, meaning that the sensor output
goes up as the temperature goes up.
• Some temperature sensors have a negative coefficient, meaning that the sensor
output goes down as the temperature goes up.

13. UV SENSOR
• It is used to detect the intensity of incident ultraviolet radiation.
• Skin cancer in now a days become an increasing human health issue. To reduce
this skin cancer we use this sensor.

14. ALARM BUZZER
• When a child is separated from the parent then the parent can locate their child by
sounding a very loud alarm.

15. WORKING
• Parent sends an SMS using some keywords such as TEMPARATURE, LOCATION,
SOS, BUZZ etc;
• This results in knowing the location of their child.

16. RESULTS

17. ADVANTAGES DISADVANTAGES
• Staying Connected
• Data Accuracy
• Efficiency
• It can be used in any cell phone and
doesn’t necessarily require an
expensive smart phone
• High Cost but once it is implemented
the expenses can be reduced

18. CONCLUSION
• The child safety wearable device is capable of acting as a smart IoT device.
• It provides parents with the real-time location, surrounding temperature, UV
radiation index and SOS light for their child’s surroundings.
• It is capable of holding the battery for a longer time.
