#INFINIFACTORY INVERTED SENSOR HOW TO#

Infrared radiation works on the lower end of the electromagnetic spectrum and is therefore invisible to the human eye. More about the functioning of PIR in the later paragraphs. This happens if, for example, a warm object (like an intruder) crosses ways to the signal of the device. The basic functioning is that the passive infrared sensors trigger the alarm when there is an anomaly in the infrared waves measured in the room. The PIR sensors do not emit radiation but simply receive the one that the objects nearby are naturally emitting.

This is especially useful in robotics to detect proximity.įor the physical security use case, however, passive infrared sensors (PIR sensors) are definitely more widespread. Through this technology, the sensor can not only detect movement in an environment but also how far the object is from the device. This radiation hits the objects nearby and bounces back to the receiver of the device. The functioning depends on if the sensor is active or passive (PIR).Īctive infrared sensors work with radar technology and they both emit and receive infrared radiation. Infrared sensors, as mentioned above, work with infrared radiations.

In the next paragraphs, we will dive into how these sensors work, what are the ideal use-cases, and how to choose the best infrared sensor for your business or home. The two types of infrared sensors are active infrared sensors and passive infrared sensors with these last ones being the preferred ones in the context of physical security.

The main use-case of this device is within physical security and, in particular, for intrusion detection purposes. Infrared sensors are a specific type of motion sensors that use infrared radiations.
