Wireless Temperatures arround the house

Archiver

Hi

I'm looking for the cheapest way of sending
temperature readings from rooms all around my house
to control my zonal central heating system.

I'm looking for anything that can send a wireless temperature related
signal, be it digital or analogue, (can be calibrated or converted to
temperature reading at reciever by STAMP) to a central reciever that
can understand recieving several temperatures from different
transmitters.

Example

Many Transmitters sending say a resistance related signal and a Room
code to a Central Reciever that can sort the Room Signals out and
convert the Resistance to Degrees.

Must be cheap <$10 per room temperature ?

Any pointers would be greatful

Cheers

Chris

Wireless is going to drive up your cost-per-sensor and is not without its
problems. ·What about Dallas 1-Wire? ·The BS2p can ·use any pin to
communicate with 1-Wire devices, like the DS1820 temperature sensor. ·Dallas
also makes a 1-Wire digital switch. ·This would let you do remote control
over that same bus.[/font]

Wiring is the problem hense wireless requirement.
