This article deals with Pseudo-Schottky diode consists of InP-p gas sensor with metallized layer of Palladium. In a first time, original results of carbon monoxide action (CO) on metallized layer are shown. It can be seen that Pseudo-Shottky diode submission to CO avoided the degradation of gas sensor parameters by ozone. Then an original methodology of measurements that takes avantages of gas sensor selectivity towards ozone, to follow in real time variations of concentration, is described.
