Hi all. Don't know if this is the right place to ask this, but if not, maybe someone can put me straight.
I have a wind velocity sensor that has an I2C interface. I have it connected to an Arduino Nano and it works fine. However, I now need to extend the I2C to several metres - probably at the limit for the high speed I2C bus in use. So I was looking for a simple solution, and came across the Adafruit DS2484 I2C to 1-Wire Bus Adapter Breakout board.
So my question is, can two of these boards be effectively connected back to back - so one at the sensor end I2C in, 1 Wire out, and another at the Nano end 1 Wire in, I2C out, with several metres of 1 Wire bus cable in between ?
Or am I just being naive here ? I have to say that I don't have a great understanding of buses and having devices talking over distance.
TIA for any help or advice. Its appreciasted
