The invention provides a sensor arrangement for monitoring the concentrat of moisture and gaseous substances in ambient air. A gas sensitive intermediate layer is sandwiched between top and bottom electrodes, each of which comprises first and second interdigitated conductive elements, which are coupled to an opposite polarity voltage. The top and bottom electrodes are super-imposed on opposite sides of the gas-sensitive intermediate layer, with fingers of the top electrode having a voltage polarity which is opposite that of adjacent super-imposed fingers of the bottom electrode.
