Has anyone any experience of running an I2C bus from a PCB to a remote I2C device ? I am thinking of connecting a remote Dallas Semiconductor I2C temperature sensor IC to a micro over a length of 4 or 5 metres of wire. The temp sensor would be fixed to the ceiling to measure room temperature and the micro would be in a monitoring / control box on the wall.
Could I run this at the typical 400 KHz clock speed with a decent bit of screened cable ?
