Wesley Eccles created this IoT fire detection system. Instead of heavy infrastructure drones deliver IoT beacons for a mesh system. From Hackster.io:

This device is meant to be dropped from a plane/ helicopter deep into the forest. Current fire detection systems require a large infrastructure setup, however, this system is designed to drop and forget. No maintenance or even ground access is needed to deploy the system. Using LoRa as a way to communicate between nodes, the system will detect a wildfire before it can get out of hand.

Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
