Hello everybody,

I'm into a Design project of a Meteorogical Station and I need to introduce a frequencial output (sensor HS1101 output [including all the circuit conditioning]) to the arduino board, and I'm looking for info but my search wasn't satisfactory.

If anybody knows how I can do it, I'll be very thankful.

Thanks a lot,



Assuming you mean the 555 circuit as "pulse conditioning", I'd guess that the pulseIn() function would do what you want.



Yes, it is this circuit. I'd try it,
