In this DIY, we are going to demonstrate a project of “Home and Office Basement Flood Alarm”. Even though floods don’t generally rate high on our list of concerns. On the off chance that we get an early warning about one. So, we should find a way to “prevent” as much harm and damage as could reasonably be expected, including risky substances inside the floodwaters that could enter our homes.
This home and office basement flood alarm will show you signals when the flood begins to enter your places. The circuit gives early signals and alarms because of which it is conceivable to make a quick move to spare your machines and furniture.

Basement Flood Alarm Circuit
Working Explanation
The circuit is not so difficult to make and requires just a couple of affordable segments. The two wires marked sensors ought to be connected in the basement where you figure it will handily interact with the floodwater. You can likewise associate a few inches of “steel bars” with the sensor wires for better execution. For sound signal, a UM66 melody IC is utilized which gives a sound alert when the sensors identify a flood. The working voltage of the circuit is 3V to 4.5V DC. The circuit expends exceptionally low current because of which it is perfect to utilize batteries for driving it. The pack of a few 1.5V AA batteries will keep going extremely long.
Applications and Uses
The Home and Office basement flood alarm circuit is used to give signals about the flood which helps you to prevent much damage and harm as could reasonably be expected.
