You can now obtain the files for making a water detector at home yourself. This can be used for monitoring plants, animal water bowls, water pumps, etc.

You make this at your own risk though. Make sure that you do not use any kind of live voltages near your pet.

The circuit is a transistor based water detector which uses one NPN transistor and a few more complementary parts to achieve the task. This cicuit uses a low voltage potential on the sensor side which is safe for palnts and animals alike.

This device can be powered with a 9 volt battery.

The full component list is:

  • 9 volt battery
  • BC547
  • Battery clip
  • PCB clad board
  • wire

And thats it. You spend less that Rs20 which is around $0.25 (or 25 cents)

If you make this, tag me on twitter and let me know!

All the best!
