Re: pressure sensor and digital temp/humidity...

hi, yes, i have already checked that sensor, but the response is not linear, so you cannot have an accurate convercion between output voltage and humidity (or between resistance and temperature), for this reason i'm looking for a digital sensor.

Re: Ultra-Sonic Ranger - GH-311RT DATASHEET?

hi, i don't think that the gh-311rt will work as distance meter, it seems to have just an output pin with HIGH LOW status when obstacle detected, the PING mudule from sparkfun has input output signal pin.
or not!?
thank you
