Dryad participated in a prescribed burning in Guadalajara

We had the chance to participate in a prescribed burning in Guadalajara (Northern Madrid, Spain) and test the Silvanet Wildfire Sensors under real-world conditions.

Prescribed burning is a method of using a controlled fire on the ground of the forest to clear the fuel (brushes, needles, etc) and thus reduce the threat of a real wildfire to spread to the crowns. This method was originally used by indigenous people (e.g. in the USA and is gaining traction as a method to prevent megafires which are increasingly threating our forests.

To prepare for the burn, we placed 10 sensors and one Sivanet border gateway in the target 100x100m woodland area.

Next, the fire fighters of Infocam - the local wildfire suppression service - started the fire from the top of the hill and then downward the slope. Silvanet performed extremely well; within just 5 minutes after the fire was started, the first sensor triggered and the fire alarm was sent.

It was a very dramatic scene, much bigger than in any other fire tests that we have done before. We tried to capture the process using our drone to get a better understanding of the spread of the fire and extent of the smoke generated.

During the burning, one of our sensors which was placed in the area took a serious beating by the fire. However, when we checked it out, we were amazed to find the brave little bugger managed to survive and was still transmitting data back to the system despite being molten. We will keep that courageous sensor as a trophy and sign of resilience!

We would like to thank our partners STIHL and Infocam for enabling us run the first real-world test successfully. The team is excited to see how well our Silvanet operated in this real-time fire. Dryad has successfully delivered a quick and effective fire detection system as promised. We hope to deploy our Silvanet widely to protect our precious forest for our planet, and for our future generations.
