Radio frequency based real time Child Monitoring and alarm system

INTORDUCTION
Background
The Child Monitoring System is a system which is developed using RF technology to monitor child in a certain area. The system is separated into two parts. This thesis will concentrate more on parent’s part while the thesis on child’s part will be concentrated by other person. Parents have the master device while the child has the slave device. The master device is sending and receiving data through RF TRANSMITTER AND RECIEVER by using some command which is programmed into PIC microcontroller The device has liquid crystal display (LCD) and buzzer in order to alarm parents about their child who probably out of RF range or the child is drop the slave device or can be both of the causes.


Problem Statement
Nowadays, there are many cases of missing kids in the whole world. Due to United States Justice Department reports,
797,500 children (younger than 18) were reported missing in a one-year
period of time studied resulting in an average of 2,185 children being reported missing each day.
203,900 children were the victims of family abductions.
58,200 children were the victims of non-family abductions.
115 children were the victims of “stereotypical” kidnapping. (These crimes involve someone the child does not know or someone of slight acquaintance, who holds the child overnight, transports the child 50 miles
or more, kills the child, demands ransom, or intends to keep the child Permanently.)


Develop the system only for the parent’s part
The master device has to search and initiate connection with the slave device by creating the SPP connection. SPP is used for host to communicate with RF TRANSMITTER AND RECIEVER and its understanding language is AT command.

Develop the power module to supply 5V to the PIC and RF TRANSMITTER AND RECIEVER
The main components such as PIC microcontroller, SKKCA RF module and LCD need only 5VDC power supply to function correctly. If the supply is over than 5VDC, they could damage.
