![]() ![]() ![]() Near Infrared, Mid Infrared, Far Infrared. Infrared spectrum is categorized into three regions based on its wavelength i.e. IR sensors use infrared radiation of wavelength between 0.75 to 1000µm which falls between visible and microwave regions of electromagnetic spectrum. Some of its features are heat and motion sensing. IR sensor is a simple electronic device which emits and detects IR radiation in order to find out certain objects/obstacles in its range. This post will discuss about what is Infrared Sensor, its working principle, how it works, types, applications, advantages and disadvantages. Infrared Sensor is most used sensor in wireless technology where remote controlling functions and detection of surrounding objects/ obstacles are involved. ![]()
