I know this chip needs 3.3 volts but I see in the literature for this product that it can operate at 5v on the I2C line. Is this true and will the product last at 5v?

The working voltage is 3~5V. If you view the wiki that you can see it(Sorry for the wiki link,it was wrong before).

I'm thinking about using these as switches for my home automation system. Can we make the cable long enough between the feelers and the INT ? 1m, 5m, 15m ? Or between the INT and the seeeduino ?
