Anybody tried to connect more than one Temp sensor? The script supplied works with any port A0, A1, A2, A3 with out changing the line in the script which is set to A0.

Tried changing it to A1 and it still works in all ports? Why?

Found the answer

Any analogue input not attached to a sensor can pick up ghost voltages from a working input and or hand touching the board.
