The controller processes the input information from sensors.

The ECM (Engine Control Module) controls the exhaust emissions with information it receives from various sensors.
The technical characteristics of the digital sensors when making your choice of the digital modules PLC is that they should be highly sensible.
Digital sensors produce digital output (0 or 1) which can be easy to communicate directly with a microcontroller. Analog sensors provide analog outputs which one must firstly digitize to sense the level. Analog sensors are generally more accurate.

Sensing devices typically fall into two main categories: analog sensors and digital sensors. Analog sensors produce a continuous output signal that corresponds to the physical quantity being measured, such as temperature or pressure. In contrast, digital sensors provide discrete values, often in binary form, which represent the measured quantity, making them easier to interface with digital systems. Both types are essential for various applications in automation, control, and monitoring systems.

In science, a control center refers to a component or system that regulates and coordinates physiological processes or responses. It typically processes information received from sensors (or receptors) and sends signals to effectors to maintain homeostasis or achieve a specific outcome. For example, in biological systems, the brain often acts as a control center, integrating sensory inputs and orchestrating appropriate responses to maintain internal balance.
The correct order of a homeostatic control system is: Stimulus - a change occurs in the internal or external environment. Receptor - sensors detect the change in the environment. Control center - processes the information and determines the appropriate response. Effector - carries out the necessary response to restore homeostasis.
A Programmable Logic Controller (PLC) is an industrial digital computer designed for automation of manufacturing processes. It works by continuously monitoring input signals from sensors, processing these inputs based on pre-programmed logic, and then sending output signals to control devices like motors or valves. The PLC operates in a loop, executing its program to respond to changes in the input conditions in real-time, ensuring efficient and reliable control of machinery and processes.
