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.

[ What is claimed is:] [1.]1. Air moisture controlling apparatus comprising a humidity sensor operable to produce an electrical signal the level of which is determined by the humidity of air at the sensor, and microprocessor means coupled to the sensor whereby to receive said signal, in which the microprocessor means is arranged to provide an output air moisture control signal when the measured humidity exceeds a reference base of humidity by a predetermined amount; wherein the microprocessor stores humidity values indicated by the sensor signal, calculates an average value over a time period, and uses the calculated average as the said reference base of humidity.
