Proximity Sensors
It is also known as proximity switch. It is developed to detect the presence of an object within a certain range. It emits the beam of radiations and then detects the change in the field due to the presence of any object. There are various types of proximity sensors:
Inductive Proximity Sensors: It uses electromagnetic induction to find the metallic objects within a particular range. It is used in industrial automation to detect the metallic parts moving on conveyor belt.
Capacitive Proximity Sensors: It uses the change in capacitance to detect the presence of objects. It can detect non-metallic materials like plastics and liquids. It is used in touch screens, liquid level sensing etc.
Sensors in Electrical Engineering
Sensors are the detection devices of the digital world. It senses the physical change in the environment and converts the sensed data into machine-readable or understandable language. The sensors are of two types i.e., analog and digital sensors. As the name suggests, an analog sensor provides analog values which is a set of infinite values. On the other hand digital sensor converts the data into digital signals which is a set of finite values. There are various types of sensors that are being used in various fields like the automation industry, healthcare sector, and many more.
In this article, we will study sensors, types, and practical applications.
