Water level Alarm + Indoor Wireless Comunication

I made a DIY alarm for my indoor pond.
I used these things:

9V battery
9V buzzer
battery adaptors
swich floters
indoor wireless comunication system


The comunication system is sending signal to another one that i have in my room!The pond is in the basement...








Maybe you can understand it better in a vid that i made

It was cheaper from an ID cam, and it was DIY!!

Please feel free to ask anything!

GREAT idea!

it'd be great if the baby monitor was a pager of some kind. [longer range]

Signal comes threw electricity cable so range doesn't mater!
