Bluetooth Water level for smart phones Answered
I want to know how this would be accomplished PLEASE. Looking to make a bluetooth system that sends water level of a tank to a smart phone. I would think the most cost effective way to do this is by using a bluetooth module and float switches. The module would send three levels full, half and empty, so say all float switches are triggered it would be full, only one it would be half and if none it would be empty. What do i need to build this.
