Abstract: Method for Internet of Things (loT) sensors and GPS based system 
for child health monitoring and movement tracking 
The present invention is related to a method and system for child health and movement 
monitoring based on Internet of Things (loT) sensors and GPS system. More specifically, the 
field of the proposed invention is to build a complete automated system for child health and 
movement monitoring using Internet of Things (loT) sensors and GPS system using already 
available internet infrastructure like internet infrastructure and smartphones. The said 
system comprises loT sensors based wearable tag which may be in the form of a bracelet or 
any other preferable wearable form which is fastened on the body of the child to be tracked.  
The wearable tag may establish local wireless connections within location loT hubs or with 
wide area network. The loT based wearable tag establishes local wireless connection through 
Bluetooth standard protocol or WiFi protocol while global wireless connections through 
standard RFID Zigbee protocol. An electronic wearable tag is registered with each and 
individual child to be monitored along with the photo of the child and details of the guardian.  
The said system can be accessed through mobile terminal, laptop, personal digital assistant 
or any kind of computing device providing user interface and registering child with particular 
tag and associating photo of the child and details of guardian/caretaker like contact number, 
email-id etc. with the tag through the camera of the said device. Further, the information with 
respect to sending notification/alarm of the particular child to be monitored like email-id, 
mobile number and any other information are also registered through the User interface. The 
wearable tag uses global positioning system to track the movement of the child. If the 
movement of the child is not within the permissible premises, then the said system sends 
alarm/notification to the caretaker/guardian of the child. The said system also provides the 
history of the movement of particular child plotted on the map. The said system is also 
competent enough to send alarm/notification in case the wearable tag is detached from the 
child. The tag also comprises various loT sensors equipped with various biomedical sensors to 
monitor health related data including but not limited to body temperature, heart rate 
variability, motion, sleep, stress, fitness level, recovery level, effect of a workout routine on 
health, caloric expenditure etc and environmental data. If any abnormal health data and 
environmental data is observed by the tag then the said system sends alarm/notification 
along with the data to the caretaker/guardian of the child. Thus, the said system is fully 
automatic and competent enough to monitor the movement and health of the child and 
provides alarm/notification in case of abnormal conditions. The proposed system can be 
adopted by the schools, creche, caretakers or individuals for providing additional safety and 
security to the child.  
1
Register the child along with photo and guardian/caregiver detail 
with email-id and mobile number (201) 
Collect location, physiological and health data by smart wearable 
devices having GPS system and biomedical sensors periodically (202) 
automatically transmitting gathered data to central server using 
communication network (203) 
Analyze the collected data regularly by central server and check 
whether the movement is within permissible premises and 
physiological/health parameter within range (204) 
2 
Send alert/notification to the registered guardian/caregiver in the form 
of email or SIMS (205) 
Sending alert/notification in case tag is detached from the child (206) 
Access the system by the authorized guardian/caregiver through OTP 
and access the data through mobile application (207)
