Advantages of infrared waves in communication
Answers
Different wavelengths of light reveal different natural phenomena, and the infrared has animportant story to tell. One of the advantages of observing in the near-infrared is that dust is transparent to it. ... Relatively cold objects invisible to optical telescopes become visible in the infrared.
Advantages of Infrared sensor
Following are the advantages of Infrared sensor:
➨It provides secured communication due to line of sight or point-to-point mode of communication.
➨The battery used in infrared devices last for long duration due to lower power consumption.
➨Infrared motion sensors detect motion in daytime and nighttime reliably.
➨The sensor does not require any contact with the product to be sensed. The infrared devices are more appropriate for targets which are close than 10 mm.
➨Infrared devices can measure distance to soft objects which may not be easily detected by ultrasound.
➨They are physically smaller in size and are more affordable.
➨It has response time faster than thermocouple.
➨It provides good stability over time.
➨No corrosion or oxidation can affect the accuracy of infrared sensor.
➨It delivers high repeatability.
