A humidity sensor and a quartz crystal microbalance (QCM) therefor, for measuring low humidity levels, and a method for preparing same. The metallic surface of the QCM is electroplated with a hygroscopic layer. The hygroscopic layer preferably includes Manganese. A salt is formed on the hygroscopic layer. The salt is preferably salt of Manganese, and most preferably Manganese Chloride (MnCl2). |
