Infrared Drones in Disaster Response

Introduction to Infrared Drones in Emergency Management

In recent times, infrared or thermal drones have become instrumental in managing disasters and emergencies. Their ability to capture and analyze thermal data has revolutionized search and rescue operations, firefighting, and environmental monitoring.

What Are Infrared Drones?

Infrared drones are equipped with thermal cameras that can detect heat signatures from various objects and living beings. These drones capture infrared radiation emitted by objects, which is then focused onto a detector array made up of microbolometers. 

Each microbolometer converts the temperature data into an electrical signal, culminating in a visible image that represents different temperature ranges with varying colors.
