The diode allows only half of the AC waveform to travel through it. Start now. This chapter provides an overview of operations research, its origins, its approach to solving problems, and some examples of successful applications. The motor again starts rotating in the same direction by releasing the reset switch. Before going in to the details of What is a Sensor, What are the Different Types of Sensors and Applications of these different types of Sensors, we will first take a look at a simple example of an automated system, which is possible because of Sensors (and many other components as well).
