Description

A low power and low cost continuous monitor of the level in a boat's clean water tanks. It uses just one PicAxe input pin to monitor three float switches and a compact 'SELECT CASE' construct in the software to simultaneously read the level and transmit the result to a receiver, which can be anywhere on the boat.
