A sensor actuator and a push-button actuator serve different functions in a control system.
A sensor actuator is a device that responds to input from a sensor. It receives signals from sensors that detect changes in the environment, such as temperature, light, or pressure, and then performs an action based on that input. For example, in a smart thermostat system, a sensor actuator might adjust the heating or cooling based on the temperature readings from a sensor. Sensor actuators are often part of automated systems and can operate without human intervention.
On the other hand, a push-button actuator is a manual device that requires human interaction to operate. It is a type of switch that, when pressed, completes an electrical circuit, triggering a specific action. Push-button actuators are commonly used in simple control systems where a user needs to manually initiate an action, such as turning on a light or starting a machine. They are straightforward and provide direct control to the user.
In summary, the primary difference lies in their operation: sensor actuators are typically automated and respond to environmental changes detected by sensors, while push-button actuators require manual input from a user to function.
