Abstract :
In this paper the microwave humidity sensor has been presented. In the device the surface acoustic waves (SAW) resonator with nafion coating was used. The sensor exhibits good sensitivity and linearity as well as the resistance to active chemical compounds. The microwave circuit presented in the paper seems to be also suitable with other chemical chemisensitive coatings for different type chemical compounds and biological agents detectors.
