For my TX i purchased these sht21 sensor. It has a stainless steel housing.

Extended the cable to 3 meters and still working fine.
2 weeks ago i ordered another one with 5 meters of cable in a different housing. Think a plastic housing will do better in a radiation shield and i had to remove a part of the pcb sealing.
