There are many drowning accidents every summer. To reduce the frequency of such tragedy, the drowning-prevented monitoring system applies the technology of IoT (Internet of Things) by Bluetooth network to develop the secure monitoring system on swimming activities. The Bluetooth is a wireless signal (2.4GHz) with the characteristic of hard passing through liquid. The waterproof tag of Bluetooth is settled on the swimming hat or goggles. The nearby smartphone will not receive the signal continually when the swimmer is under water for certain period of time that indicates the swimmer is drowned. The system would send out alert message to remind the lifesavers and parents to rescue him immediately. The system is developed for the parents to look after their children. The system will be exploited that combined with Bluetooth technology and smartphone. The parents with smartphones could receive the signals of Bluetooth that was transferred from the head of a child wearing the tag. This system will avoid the casualties of distraction which helps the parents feel relieved. |
