Methods, apparatuses, and non-transitory machine-readable media associated with relative humidity (RH) sensors are described. Examples can include receiving from an RH sensor RH information of an environment of a processing resource or a memory resource coupled to the processing resource, or both, determining that the RH information indicates an RH level above a particular threshold for the processing resource or the memory resource, or both, and disabling one or more aspects of the processing resource or the memory resource, or both, to mitigate damage to the processing resource or the memory resource, or both, responsive to determining that the RH is above the particular threshold.
