RE: Placing DS1820's

["mike" <mikegriff@xxxxxxxxxx>]

If its any help Paul I put one DS1820 in each telephone extension socket
and
utilise the spare wires in the phone extension cable

Seems to work for me as is a lot less hassle

I'm not sure how accurate the DS1820 are but they are constant so I just
modify the absolute reading with a known measured offset

Hi Guys,

I'm shortly going to be putting DS1820 (1-wire temp sensors) in each
room of the house.

The grand plan is to automate the heating and cooling of each room.
So that I can set a desired temp and the system does the rest.

What I am wondering is does it matter where in the room the sensors
are. I'm planning to mount them in the ceiling in a discreet vented box.
But
just want to check that this would be ok.

I know heat rises and therefore the temp at ceiling is going to be
higher than at body height, so I think I can just compensate for this
change.


The current plan is this.

DS1820 in each room wired back to a TOM10 with autom8it plug-in
(Available Soon)

Then a set of relays driven by autom8it (again in the pipeline)
which operate valves, hidden in the floor, by each rad.

Also there will be X10 control of floor standing AC units where available.


Regards,

Paul,
