This project converses about the design of children alert system by using Radio Frequency (RF) Frequency Modulation (FM) techniques. Children missing become pervasive and happen frequently as their parent not alert and lost sight of their children especially at public area. The main objective of this alert system is to ensure parents alert with their children that wandering from missing with limitation distance. In this alert system, the transmitter will attach to the children while the receiver part is carried out by the parents. Transmitter continuously transmits the signal to the receiver. The receiver emitted a beep sound in a few seconds during the transmission of signal from transmitter to receiver. Once the children reach the distance limitation, the signal will stop transmitting and no more sound can be heard by their parents. Repeated sound that heard by their parents and suddenly there is no more sound heard will alert their parents and notify that their children have been reached the safe distance limit. This project consist of hardware design which a simple device. Software was used to improve the circuit before fabricating on printed circuit board is done to get the expected result. The transmitter circuits were developed to transmit FM signal while the radio FM in Smartphone was used as a receiver. This child alert system will help parent alert when their child wanders alone and they will not too late to realize that their children are missing. Thus, this alert system will reduce the child missing case.
