This outline shows a gadget utilized for water discovery, when the tests interact with water, the alert sounds. It comprises of just 5 parts that are effectively accessible in the market.The IC CD4047 is CMOS-based, so focus on the static while introducing it. Tests can be any two metal surfaces. It is ideal to introduce the screws on the edges of the PCB board, along these lines you get a rack that holds the whole gadget above water and you can utilize any two screws as tests. Setting the alert is to contact the tests by hand or spot the tests of the gadget in the water and change the P1 potentiometer until you get a palatable sound from the piezo speaker.
