Sensors and Actuators

Definition

Sensors and actuators are essential components in various systems, where sensors detect physical properties and send that information to a controller, while actuators carry out commands from the controller to perform physical actions. These technologies play a crucial role in automating processes, improving efficiency, and enabling real-time monitoring in diverse fields, particularly in ecosystem management. By providing data and facilitating actions, they support sustainable practices and enhance decision-making processes.
