1. You'll need some type of float. You could try using something
like a tennis
ball with a rod through the diameter.
2. Some type of switch at the top of the travel - either a micro
switch or a piece
of metal mounted on your float and at the top of the float
support. Bent so
they touch when the float is at the desired level.
Now comes the tricky part, you have 2 options here.
3. Look into getting a door bell, or at least a door bell
transformer. Then you'll
have a 12V or 24V DC which you can connect to the switch and to a door
bell chime upstairs. Only problem is that you'll have to run
wire from where
you mount the float to where you mount the door bell.
4. Get a cordless door bell system. They are less than $25. (I
prefer the AC
powered type [plugs into a wall plug] instead of the bell being
Connect the wires form the float to the 2 connectors on the
remote button. (The
door bell buttons are battery powered. So you'll have to check
on the battery
every once in a while.)
Hope this gives you some ideas.
