Infrapunaandur

Infrapunaandur, also known as an infrared sensor, is a device that detects and measures infrared radiation. Infrared radiation is a form of electromagnetic radiation with wavelengths longer than visible light, and it is invisible to the human eye. These sensors work by sensing the heat emitted by objects. All objects with a temperature above absolute zero emit some level of infrared radiation.

There are two main types of infrared sensors: passive and active. Passive infrared sensors detect the infrared radiation emitted by an object without emitting any radiation themselves. These are commonly used in motion detectors for security systems and in non-contact thermometers. Active infrared sensors, on the other hand, emit their own infrared radiation and then detect the reflected radiation. These are often used for proximity sensing, object detection, and in remote controls.

Infrapunaandurid are utilized in a wide range of applications. They are found in consumer electronics like televisions and air conditioners for remote controls, in industrial settings for temperature monitoring and process control, in automotive systems for features like adaptive cruise control and automatic emergency braking, and in medical devices for diagnosing and monitoring conditions. The ability to detect heat signatures without physical contact makes them invaluable in many fields.
