Here you can see the rising water level causes the foam float (with a conductive surface on top) to touch a piece of metal, completing the circuit.
This is my first week’s project. It is designed to sense when rain reservoirs are full. It is a very basic switch, but I could see that this could be very helpful for communities who don’t have access to clean drinking water. Many of these devices could be placed in trees with the LED’s positioned at the base.
I found this project really interesting because it allowed me to understand how some of the most essential pieces of technology are just an on or off switch.
The code that I used was pretty minimal, but totally sufficient for the task at hand.
Please excuse the poor design of this page, for this is also my first blog post ever!
