A drone is an IoT device that interacts with many sensors and actuators, including digital electronic speed controllers linked to engines, propellers, and servomotors. A drone is also known as an unmanned aerial vehicle (UAV), but we will definitely refer to it as a drone. Let's imagine that we have to monitor many drones.
