The document presents a child security wearable device designed to help parents locate their children easily, especially in crowded areas. It improves upon existing systems by utilizing SMS for location updates instead of relying solely on Wi-Fi and Bluetooth, incorporating multiple sensors for temperature, UV radiation, and an SOS signal. The device is capable of acting as a smart IoT device, providing real-time updates to parents while aiming to reduce costs over time.

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

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

6. 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.

7. 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.

8. OVERVIEW

9. CIRCUIT DIAGRAM

10. 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.

11. 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.

12. 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.

13. 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.

14. 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. Toreduce this skin cancer
we use this sensor.

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

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

17. RESULTS

18. • Staying Connected
• DataAccuracy
• Efficiency
• It can be used in any cell phone and doesn’t necessarily require an expensive smart phone
ADVANTAGES

19. DISADVANTAGES
• High Cost but once it is implemented the expenses can be reduced
• Battery

20. FUTURE SCOPE
• Camera module
• Apps

21. • 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.
