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.
➨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.
Disadvantages of Infrared sensor
Following are the disadvantages of Infrared sensor:
➨Infrared frequencies are affected by hard objects (e.g. walls, doors) , smoke, dust, fog, sunlight etc. Hence it does not work through walls or doors.
➨Infrared waves at high power can damage eyes.
➨In monitor & control application, it can control only one device at one time. Moreover it is difficult to control things which are not in LOS (Line of Sight). It requires line of sight between transmitter and receiver to communicate.
➨It supports shorter range and hence it performance degrades with longer distances.
➨It supports lower data rate transmission compare to wired transmission.
