Building a Capacitive Liquid Sensor

Step 6 Make Capacitive Sensor

For testing i used aluminum foil and a plastic water bottle, It will work with any container so long as it isn't metal.

You can use any type of wire but any non shielded lines will provide poor performance.

You can use any 2 pins, I chose 22 and 23.

Connect one side to ground and the other to a resister and 2 I/O pins.

2 pieces of aluminum foil on aether side. One wire soldered to each.

One acts as a ground, the other sens.
doesn't matter witch way around you set it up.

The sheets should go from the bottom to top of the container.

It's a bit of a pain to solder aluminum foil but can be done. otherwise anything conductive.

 Hey I one question did you cut the aTinFoil in two pieces and you put them in the sides of the conteiner?.
