Temperature sensor functionality

If you have a numbers of sensors connected to the same pin on the RPi - you might find it useful to have a look at this thread...

DS18B20 not functioning

I'll try 1.5k tomorrow and report back. I'm just surprised that when I clamp a new sensor and an old one together, it doesn't work and when I take two old ones or two new ones, it works. Then it can't normally be due to the resistance?!

I've never had more than 2 or 3 sensors connected to the same pin, so may not be able to help you.
