1 Wire temperature measurement with ds1820

Postby dreambox » Tue Dec 21, 2010 11:45 pm

Hi,

I would like some reaction from fellow colleagues about receiving measurements of temperature in different rooms.
Now I measure it with a 1wire network, and 4 pieces of ds1820. In my new home I would want to measure every room. Total 11 pieces and with a total length of 90 meters

How do you measure it, at what hight and how is your mechanical construction?
Are the sensors in the wall, in a junction box behind a switch, etc.
Do you use a loop or more (star network)

Alex

I have 14 1-wire devices on two 1-wire networks using DS2490 USB bus masters. I have temperature sensors in every room but they are just shrink-wrapped and hidden at the edge of the carpet. All the sensors are in parallel, so I guess that's a star network!
