Apparatus for controlling air moisture utilises a humidity sensor to produce an electrical signal indicative of air humidity. The signal provides input to a microprocessor which stores humidity values indicated by the signal and also uses the signal to compile a humidity reference base which may be derived from a time average of the relative humidity and, optionally, the current value thereof. The microprocessor further provides an output air moisture control signal when the sensed humidity exceeds the reference base by a predetermined amount.
