Operating mechanism: The solar panel will convert heat energy into electricity and store it in the battery to serve the broadcasting activities. Thanks to the automatic programming system, the timer, at the default time, the transmitter will automatically broadcast according to the content recorded in the memory card, transmitted to the loudspeaker.

The recorded drowning prevention propaganda messages on USB will be broadcast during peak hours every day. In addition, this system can combine propaganda on forest fire prevention, Covid-19 epidemic prevention, environmental protection reminders, etc.

According to Mr. Nguyen Cao Loi - Secretary of Thanh Dong Commune Youth Union, the cost to build a solar-powered drowning warning system is about 3 million VND.

The advantage of this propaganda system is that it is mobile, compact, does not use an external power source, so there is no need to pull wires. Every day, at the exact time people start swimming in the river, the system will automatically broadcast messages about drowning prevention, without the need for an operator...

Mr. Loi added: The project will contribute to promoting drowning prevention and warnings to people, especially children. The system is also equipped with some rescue tools for people to use when bathing, to minimize drowning.
