Key Concepts

Actuator

An actuator is a component that converts control signals into physical action. It takes input from a control system and produces movement or another tangible change in the environment by transforming energy, typically electrical, into mechanical work. The primary purpose of an actuator is to perform an action in response to commands, thereby enabling systems to interact with and manipulate their surroundings.

Sensor

A sensor is a device that detects and responds to changes in the physical environment. It converts physical parameters such as temperature, light, pressure, or humidity into electrical signals that can be processed by control systems or computers. The primary purpose of a sensor is to provide data about the environment, enabling systems to monitor, analyze, and take appropriate actions based on this information.
