Bluetooth Water level for smart phones Answered

I need some help in making a bluetooth water level that uses standard float switches. 

Once a float switch is triggered it would close or open a circuit then the data of which circuits are opened or closed can be used to determined the level in the tank. This will be sent via bluetooth to a mobile device were i will develop an app to visualize the data.

Please i need info on how to setup the electronic components.

You can start here.


A quick internet search will yield similar projects using a micro controller like the arduino. Most of them include an LCD display. In your case rather than using a display you'll want to use a bluetooth shield to send the data out to your phone.
