➨It supports shorter range and hence it performance degrades with longer distances. It requires line of sight between transmitter and receiver to communicate. Moreover it is difficult to control things which are not in LOS (Line of Sight). ➨In monitor & control application, it can control only one device at one time. ➨Infrared waves at high power can damage eyes. Hence it does not work through walls or doors. walls, doors), smoke, dust, fog, sunlight etc. ➨Infrared frequencies are affected by hard objects (e.g. Disadvantages of Infrared sensorįollowing are the disadvantages of Infrared sensor: ➨No corrosion or oxidation can affect the accuracy of infrared sensor. ➨It has response time faster than thermocouple. ➨They are physically smaller in size and are more affordable. ➨Infrared devices can measure distance to soft objects which may not be easily detected by ultrasound. The infrared devices are more appropriate for targets which are close than 10 mm. ➨The sensor does not require any contact with the product to be sensed. ➨Infrared motion sensors detect motion in daytime and nighttime reliably. ➨The battery used in infrared devices last for long duration due to lower power consumption. ➨It provides secured communication due to line of sight or point-to-point mode of communication. point to point and diffuse.Īctive vs Passive Motion Sensor> for more information.įollowing are the advantages of Infrared sensor: The Infrared communication network works in two modes viz. Modulation type: Pulse Position Modulation.Number of devices: 2 in connection mode.Data rate: 300 to 115200 bps (Serial Infrared), 4 Mbps (Fast Infrared).Sensing range or distance: 10 to 30 meters.It is also used for data communication for monitoringįollowing are the characteristics of Infrared waves: It is also used to detect motion of the object. It is used to measure heat emitted by object or human beings. It mentions Infrared sensor advantages and Infrared sensor disadvantages.ĭefinition: The Infrared sensor is a device which uses infrared waves to senseĬharacteristics of surroundings.
