How do infrared sensors work? | Sensor Infrared
Infrared sensors operate on the principle of detecting and interpreting infrared radiation. This type of radiation is invisible to the human eye but can be sensed by specialized sensors. Infrared sensors consist of an emitter and a receiver. The emitter emits infrared radiation, while the receiver detects the radiation reflected or emitted by objects in its field of view.
When an object enters the sensor’s range, it reflects or emits infrared radiation. The receiver detects this radiation, and the sensor’s electronics process the received signals. By analyzing the intensity and frequency of the received signals, the sensor can determine the presence, distance, and even temperature of the object.
Infrared sensors can be equipped with different technologies to enhance their capabilities. Some sensors use passive infrared (PIR) technology, which detects changes in the infrared radiation emitted by living beings. Others utilize active infrared (AIR) technology, where the sensor emits infrared radiation and measures the time it takes for the signal to bounce back after hitting an object.
In summary, infrared sensors work by emitting and detecting infrared radiation to perceive heat and movement. They convert this information into electrical signals, providing valuable data about the surrounding environment.
