This type of analyzer is used for carbonated drinks, whereas a nondispersive analyzer is used in most of the commercial IR instruments, for automobile exhaust gas fuel leakages. This LED looks similar to a standard LED and the radiation which is generated by this is not visible to the human eye. This sensor is analogous to human’s visionary senses, which can be used to detect obstacles and it is one of the common applications in real-time. Once the infrared transmitter generates emission, then it arrives at the object & some of the emission will reflect back toward the infrared receiver.
