The document proposes a wearable device that ensures child safety and assists visually impaired people by tracking their location. The device uses sensors like GPS, GSM, and ESP32 to detect the wearer's location and share it with caregivers. It aims to address limitations of existing systems by providing a cheaper design that is compatible with multiple platforms and uses GSM for reliable communication of alerts and location via SMS and email with a Google Maps link. The proposed device detects events using an accelerometer and tracks location every 10 minutes using GPS. It sends alerts to caregivers' phones in case of emergencies or when manually activated by an on-board button.

3. Objective
• To implement a wearable device that ensures the safety
against child abduction & to assist the visually impaired
people by tracking their location and to share the
information to the care taker.

4. Abstract
• Now a days it is difficult to parents to monitoring their children in busy
life. The smart wearable device for child safety and assist to visually
impairred person with location tracking system is developed by using
GPS, GSM, Wi-Fi and ESP32 module.

2016 Children Location Monitoring On
Google Maps using GPS and
GSM Technologies.
In this paper, a prototype Children
Location Monitoring System
(CLMS) is implemented using
Global Positioning System (GPS)
and Global System for Mobile
communications (GSM)
technologies. This system can help
the parents and the school
authorities to monitor the children
when they leave the school or they
go missing.

2016 An Innovative Approach for
Women and Children’s Security
Based Location Tracking System.
In this system contains GPS to
detect location and GSM
mechanisms to pass their current
location to any one of the trusted
contacts as a google map link and
services are provided to track the
locations from that moment
onwards to save the person.
S,Agarwal 2018 Student Tracking System. The IOT based live student
tracking system is a mobile
application ensuring the safety
and security of the students.

7. Existing system
• Methodology Proposed by Sunehra @ 2016 - Children location monitoring system (CLMS)
• Methodology : Track their kids location (google map link) through short message
services (SMS).
• Methodology Proposed by Padmanadhan @ 2017 - Personal tracking system (PTS)
• Methodology : integrates both GPS and GSM technologies to detect and track the
location of the target.
• Common Drawbacks in both methods :
• Failure of network
• Network Overload(Time delay)

8. Proposed system
• The currently available wrist band tracking devices are either GSM based
• This research is aimed to develop a viable & portable wristband tracing system for
children who are in trouble (i.e.,The children who are lost their physical condition.)
• The proposed device is cheaper to design and compatible to various platform like
android,IoS,windows etc…rather than apps .GSM is better option because it can
support both SMS and Emails
• Advantages
• Heterogeneous wireless network to guarantee the message is derived
successfully.

11. EXPLANATION
ON-BOARD BUTTON
• The on-board button also serves as an emergency button when CS/VIALTS is activated .
• If the event happens alert the action did not get trigger , press the on board button for one second to
toggle all the alert action manually by sending SMS and Email.
ACCELEROMETER SENSOR
• Accelerometer sensor is used to detecting the events.

12. • GPS MODULE
• The location sensor is used to communicate with the global positioning satellite
receiver in phone.
• GPS location will be gathered from the GPS module every ten minutes and sore in
main control unit. This is for tracking and recording the location.

13. GSM MODULE
GSM modules enables the proposed system to send alert messages to caretakers mobile
phone via Short Messages Services(SMS) with a google map link for location information
through the cellular networks.

16. Conclusion
• The currently available wristband tracking devices are either GSM based
or using Bluetooth platform.
• This research is aimed to develop a viable & portable wristband tracking
system for children who are in a trouble and also for visually impaired
people.
• It is cheaper to design and compatible to various platforms like android, IOS,
windows etc. rather than apps.
• GSM is a better option because it can support both phone calls and SMS.
