AbstractThis paper describes an attempt to develop a ceramic humidity sensor having an approximately exponential dependency of its AC conductance on relative humidity and having a short response time. Ammonium paratungstate pentahydrate [(NH4)10W12O415H2O] and aluminiium sulphate [Al2(SO4)3.16H2O] mixed in different wt% are used to make thick films. It is found that the AC conductance of the thick film with 40 wt% of ammounium paratungstate pentahydrate shows an almost exponential relationship with relative humidity. SEM and XRD studies are also carried out on the film to look at the nature and constituents of the samples.
