First time user, really newb question. I currently setting up an HVAC system, im trying to convert temperature sensor info. I have changed one channel on my pololu masetro micro to input. from there i can see the raw data - voltage change with temperature - . how do i convert that input into readable Cel or Fer

James,

That will normally just require a small formula to do. Most likely the manufacturer of the sensor will have that somewhere on their site. I.e. given a voltage level via the ADC a number would be converted to a specific temp value. Once you found the formula you can probably use one of the programming modules (VBScript, Python or CScript) to convert that value. A quick search for that using google will probably get you the formula that you need.

If you have problem programming that formula, post it here.
