Has anyone else seen this? 

So I have two Pis running with temperature sensors hooked up.

Raspberry Pi 1 has: 1 AM2302 (wired DHT22)
Raspberry Pi 2 has: AM2302 (wired DHT22) BMP180 Barometric Pressure/Temperature/Altitude Sensor

What I've noticed is, the values are pretty far apart. The Raspberry Pis are separated by about 7 feet. Definitely shouldn't vary this much. And between sensors on the same pi there is a lot of variance as well.
Has anyone else seen this? Ways to calibrate them? This is kind of crazy.

Is one of the Pi's putting off more heat?

Do you guys think that it will be useful to keep a raspberry pi 2 connected to an hard disk as a file server? Thank you for your opinion.

+Daniel Bull  I have a handful of them, but needed to repurpose it and the file server wasnt being used much anymore (thanks dropbox/google drive!)  but that doesn't mean I shouldn't get some more Pis!

+Jonathan Mayer  Yep +Don Ixion is right, generally the USB itself or ethernet is the bottleneck. The processing in between doesn't matter as much until you get into a large group of users.

I'm going to use mine in my HDMIPi so I can switch the mounted Pi off and still have the screen available for plugged-in Pi.

+ThantiK you are right, my bad. I found the script which created the date and it was formatted differently '%Y-%m-%d %H:%M:%S')

If you are noob on command-line on your Raspberry PI, I have video tutorials on how to use some of the command lines on the terminal.  These tutorials use the Linux/Bash, which is the same as that of the Raspberry Pi.  I hope these tutorials are helpful in your Raspberry Pi learning.

Nice, I would have gone with SmogSmug as a brand name though :)
