Summary

In this video we show you how to build a simple water leak detector at home. We used simple components and materials such as: buzzer, aluminum foil, sponge, and tape to make the sensor structure. Let us know what do you think about this project.



How to Make it?

Cut a piece of sponge and soak it in the brine. Completely dry the sponge until it gets relatively hard. Cut two strips of aluminum foils and tape them on the sides of the sponge. Make a simple circuit using a 9V battery and buzzer and this sensor as a switch. The sensor is ready to use. After detecting the water, the buzzer starts sounding. To reset the sensor just dry the sponge!



Important Notes



The best buzzer is the one that can turn on by 3V and will not get damaged by 9V



The buzzer has + and - leads, Connect it correctly

A better tape that does not degrade by water is recommended to be used

You may use a glue, epoxy, or an enclosure box to shield the entire sensor
