can I use this to measure barometric pressure and altitude or temperature only ?
It will always do both, but you can always just ignore whichever data you don’t want.
Yep, as @ats1080s said, BMP180 gives data on Pressure and Temperature.
thanks guys .
one more question. is the any way to change temp reading from F to C ?
Right now, no. But that’s a question we’ve been getting a lot, so we’re working on it! Especially since we know a lot of guys are not going to be based in U.S., this is important.
