Length of lead on Temperature and Humidity sensor

In the datasheet you provided it talks about length of wire in section 1.9. Anything less than 10 cm should be problem free. You want to go further than that though. So you will most likely need to use a shielded cable, perhaps a shielded twisted pair. This will help to eliminate any crosstalk.

I would just follow the guidelines in that section and experiment with it to see how far you can go.
