    Hi all,

    I am wondering what length of lead I can put onto a temperature and humidity sensor similar to this http://www.sensirion.com/en/pdf/product ... -SHT1x.pdf I wish to put it into an adaptable box with vent holes in and plug it in via a plug...I am hoping I can go a minimum of 5 metres and possibly up to 10 metres in cable length?

    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.
