AVR Atmega hall effect water flow sensor FS300A

FS300A is an hall-effect based water flow sensor.

When water flows a rotor rolls and a hall sensor emit the corrisponding pulse signal.
This library implements a way to read the pulse signal and convert it to Litre\Hour.
You have to setup some timer parameters to make this library works.
Setup parameters in fs300a.h

This library was developed on Eclipse, built with avr-gcc on Atmega8 @ 1MHz.
