Comparator: police siren The comparator compares the input signal amn the reference or set point.

ELEMENTS OF A CONTROL SYSTEM | tecnologiaainhoa
The robots are built to use the unit normal light sensors, light and inflaroja contact. This sensor transform the information they receive from the environment into an electrical signal, the control system is introduced to compare it with the reference signal.
Comparator: police siren The comparator compares the input signal amn the reference or set point. When the difference between the two signals exceeds a certain value, the transistor passes from the cutting area to saturation, indicating that doferència between the reference signal and the input has exceeded the predetermined value.
Elements of control: The control action is carried out by the transistor along with the relay receiving the signal that activates the transistor. The relay is activated and when your contacts change position, light bulb.
Controlled Variable: The system inspects the order to act accordingly. I called the independent variable changes to the system, police siren such as temperature or light.
Feedback: In this circuit, the feedback occurs through the continuous monitoring of the controlled variable. And that can detect any kind of change with respect to the level of ambient lighting.
