This graph demonstrates a gadget utilized for water location, when the tests interact with water, the caution 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 an agreeable sound from the piezo speaker.

Associated with an outside resistor


R-C Common

Normal stick for building up an association with resistor and capacitor

4 A stable’ Must be kept low when utilized in a-steady mode

5 A stable Must be kept high when utilized in a steady mode

6 -Trigger High to Low change will be given to this stick when utilized in Mono-stable mode

7 Vss Ground Pin

8 +Trigger Low to high change will be given to this stick when utilized in Mono-stable mode

9 EXT Reset External reset triggers when a high heartbeat is given to this stick, resetting the yield Q to low and Q’ to high

10 Q Generates high yield

11 Q’ It is an opposite yield of stick 10, delivering a low yield

12 Re-trigger This stick is utilized in Mono-stable mode for all the while re-activating +trigger and – trigger stick

13 Osc Out

Produce swayed yield

14 Vdd Voltage supply stick
