monitor wall temperature

Other Hardware Sensors

hi i wish to know if it's possible to connect temperature sensor into arduino motherboard and check the temperature with rrdtool.
It' possible to monitor a few of rooms together to see the difference between those rooms?

Thanks

That all depends on what the heck rrdtool is.

Same response to your other thread.

I mean something like these pages you can see what means rrdtool.

I wish to use arduino to monitor wall temperature, sound level meter, and if it's possible wind meter, i wish to know what is better arduino usb or arduino ethernet?

Thanks

arduino usb or arduino ethernet?

I haven't used an Ethernet shield but shield but talking to a PC with USB is a total no-brainer with Arduino, so I guess I would go that way.

So in answer to your first post, yes it's possible to monitor temperatures and report them to a PC. I'm not convinced 1-wire is good for the distances you infer (ie seperate rooms) but it might be if you use "external power" mode as is shown in figure 5 of that first link.
