Assalammualaikum..
The block diagram for our project is as simple as this.
Description of the block diagram:
The sensor will detect the input which is moisture and wetness.
After that, it will sent the signal to the I.C NE 555. The output is at pin number 3.
At this part, the output will divide into two part. The first part is buzzer and the second part is L.E.D. When the buzzer trigger, the LED will lights up at the same time.
This is the result for our project. From here, the parents guardian will alert to the presence of the wetness.
