Sensors (Inputs)

     
                 

    Sensors play a major role in any control and automation system. Without sensors the apparatus is essentially running blind. The sensors convey details of the status of the real world in a more detailed way than any human senses can. they exist to cover most measurable quantities of the real world and include motion, temperature, proximity, light, sound, moisture and many more.  An understanding of sensors is essential in the design and implementation of any control system. The topics in this section seek to explain the basic operating principles of a range of sensors.
