General picture of Hall Effect Sensors Magnetic Field Sensors as Hall effect sensor is a sensor used to detect the magnetic field. Hall Effect sensor will produce a voltage proportional to the magnetic field strength received by a Hall effect sensor tersebut.Sensor it only consists of a silicon layer and two electrodes on each side of the silicon. By the time without any influence of the magnetic field then the potential difference between the two electrodes is 0 Volt as an electric current flowing in the middle two electrodes. When there is a magnetic field affecting the sensor is the current that flows will turn close to / away from the side that is affected by magnetic fields. This results in a potential difference between the two electrodes of Hall effect sensors, where the potential difference is proportional to the magnetic field received by the hall effect sensor.

Theory of Capacitive Proximity Sensors | How Capacitive Proximity Sensors Works? This knowledge of Sensors will help you better understand customer applications. In addition, you will be better able to describe products to customers and determine important differences between products. You should know Basics of Electricity and Basics of Control Components before attempting Sensors.  Today we learn the Theory of Capacitive Proximity Sensors and how they work? Let’s Start. Capacitive proximity sensors are similar to inductive proximity sensors. The main difference between the two types is that capacitive proximity sensors produce an electrostatic field instead of an electromagnetic field . Capacitive proximity switches will sense metal as well as nonmetallic materials such as paper, glass, liquids, and cloth. The sensing surface of a capacitive sensor is formed by two concentrically shaped metal electrodes of an unwound capacitor. When an object nears the sensing surface it ente...
