Sensors can detect gases emitted during the early stages of a fire, allowing for more efficient and faster intervention.
Around 400 early-detection sensors have been installed in the Eberswalde forest in Brandenburg, the German region most affected by wildfires.
Solar-powered sensors are attached to the trees and also monitor temperature, humidity and air pressure.
The company behind the technology, Droid Networks, says they essentially act like “an electronic nose” and can detect gases emitted during the early stages of a fire, allowing for more efficient and quicker intervention.
As soon as a fire is detected, the data is sent to a cloud-based monitoring system and fire officials are alerted.
