INFRARED SENSOR Meaning and
Definition
-
An infrared sensor refers to a device or technology that detects and measures the presence and intensity of infrared radiation in its surrounding environment. Infrared radiation is a form of electromagnetic radiation with longer wavelengths than visible light, which is not visible to the human eye but can be perceived as heat.
The infrared sensor functions by utilizing a specialized electronic component, known as a thermopile or a bolometer, which can detect variations in temperature caused by the emission of infrared radiation. These sensors typically consist of multiple detection elements arranged in an array, allowing for the simultaneous measurement of multiple points or a larger area.
The operation of an infrared sensor relies on the principle that all objects emit some level of infrared radiation based on their temperature. The sensor detects this emitted radiation and converts it into an electrical signal, which can be further processed and analyzed. By measuring the intensity of infrared radiation, the sensor can provide valuable information about the temperature distribution or the presence of objects without physical contact.
Infrared sensors have various applications across multiple industries. For instance, they are commonly used in security systems for motion detection or intrusion alarms. They are also utilized in environmental monitoring to analyze temperature patterns and identify thermal anomalies. Moreover, infrared sensors find extensive usage in manufacturing and automation processes, where they facilitate object detection, temperature monitoring, and quality control.

Etymology of INFRARED SENSOR
The word "infrared" is composed of two parts: "infra-" and "red".
The prefix "infra-" comes from the Latin word "infra", meaning "below" or "beneath". It signifies something that is situated or occurring beneath, lower, or less than something else. In this context, it refers to the electromagnetic spectrum, where infrared radiation is situated below the visible light spectrum.
The term "red" originates from the Old English word "read", which is derived from the Proto-Germanic word "rauthaz". It refers to the color red, which is at the higher end (longer wavelength) of the visible light spectrum.
The word "sensor" comes from the Latin word "sensus", which means "sense" or "perception". A sensor is a device or an organ that detects or senses certain physical properties or changes in its environment.
