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.

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.
The ecm (engine control module) controls the engine functions based on the information it receives from various sensors.
Digital sensors are devices that convert physical phenomena, such as temperature, light, or pressure, into digital signals that can be processed by computers or microcontrollers. Unlike analog sensors, which produce continuous signals, digital sensors output discrete values, often in binary form, making them easier to integrate with digital systems. They are widely used in various applications, including consumer electronics, automotive systems, and industrial automation, due to their accuracy and reliability.
