Abstract
A salt-based method to monitor and log the time periods a data center air's relative humidity goes above a predefined limit. The choice of the salt is such that its deliquescent relative humidity is equal to the desired limit, so that above the desired limit, the salt gets wet and therefore electrically conductive. An alarm can then give notice that relative humidity levels are above acceptable levels so that remedial action may be taken before problems such as electronic malfunction develop.
