Distributed sensor communication

[jasiek]

Hey,

I'd like to install a couple of analog sensors (temperature, mostly) in my house. What I'm looking for is a simple way to connect them so that I can read the state of each sensor through a bus of some sort. Ideally, I'd like to connect a 4-wire cable to each sensor and read them through a microcontroller board like the Arduino.

I've looked at both I2C and 1-Wire, but both seem to have a range which is too short for my scenario.

What should I use here?

Thanks,
jan

What is your range and sensors are for temperature and ????

I want to use a couple of LM35 sensors, and hook them up to an ADC to which I can then talk using the bus. Apart from that, I'll need a couple of sensors that would simply check whether windows are closed, etc.
