Abstract
Most of the huge forest fires starts in partial combustion. In the beginning of smouldering fire emission of hydrogen in low concentration occurs. Therefore, hydrogen can be used to detect forest fires before open flames are visible and high temperatures are generated. The hydrogen sensor which has been developed is a metal insulator semiconductor (MIS) structure which allows an economical production. Due to the low energy consumption an autarkic working unit in the forest was established. In this contribution first experiments are shown demonstrating the possibility to detect forest fires at a very early stage using the hydrogen sensor.
