Early Forest Fire Detection Using Low Energy Hydrogen Sensors

Blog Article

The North-east German Lowlands is a region with one of the highest forest fire risks in Europe.In order to keep damage levels as low as possible, it is important to have an effective early warning system.Such a system is being developed on the basis of a hydrogen sensor, which makes it possible to detect a smouldering forest fire before the development of open flames.

The prototype hydrogen sensor produced at the Humboldt University Berlin has a metal/ solid electrolyte/insulator/ bilstein shocks jeep xj semiconductor (MEIS) structure, which allows cost-effective production.Due to the low energy consumption, an autarchic working unit could be installed in the forest.Field trials have shown that it is possible to identify a forest fire in its early stages when hydrogen concentrations are still low.

A significant change in the signal due to a fire wella color charm 050 cooling violet was measured at a distance of about 100m.In view of the potential impacts of climate change, the innovative pre-ignition warning system is an important early diagnosis and monitoring module for the protection of the forests.
