We present results on research and development of catalytic sensors fabricated by planar technology on anodic alumina membranes. A method to detect methane was developed which prevents humidity from affecting the sensor performance and, at the same time, reduces energy consumption. The method, based on step heating the sensor during measurements, enables the power consumption of the sensor to decrease from 35 mW typical of the conventional measurement method to 1.2 mW. As a result, a wireless sensor node equipped with a planar sensor and powered by three AA batteries could operate for about one year.

Abstract

We present results on research and development of catalytic sensors fabricated by planar technology on anodic alumina membranes. A method to detect methane was developed which prevents humidity from affecting the sensor performance and, at the same time, reduces energy consumption. The method, based on step heating the sensor during measurements, enables the power consumption of the sensor to decrease from 35 mW typical of the conventional measurement method to 1.2 mW. As a result, a wireless sensor node equipped with a planar sensor and powered by three AA batteries could operate for about one year.
