Infrared Sensor (IR Sensor)
IR sensor can detect and respond to the IR radiations. IR radiations are the type of electromagnetic radiations which has longer wavelength than visible light. It is used in the fields like detecting presence of any object due to their temperature variations.
Working
- IR sensor consist of two main components i.e., emitter and a receiver.
- Emitter consist of an IR LED that emits infrared light.
- The receiver senses the IR radiations and converts it into the electrical signals.
- The strength of these electrical signal, describes about the presence of any object
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.
