Working principle and characteristics of infrared sensors 2

2. Infrared emitter tube: The infrared sensor contains an infrared emitter tube, which is used to emit an infrared beam.

3. Infrared receiver: The sensor is also equipped with an infrared receiver to receive infrared radiation in the environment.

4. Signal processing: Infrared signals are converted into electrical signals through processing circuits, and then accurate signals are obtained through amplification, filtering, and other measures.diode

Features:

1. Non contact: Infrared sensors do not require contact with objects and are suitable for situations that require avoiding pollution or maintaining a safe distance.diode

2. Quick response: Infrared sensors have a fast response speed to changes in the environment and can monitor environmental conditions in real time.diode

3. High sensitivity: Infrared sensors are highly sensitive to infrared radiation and can recognize small changes.

4. Multifunctionality: Infrared sensors can be used in various application scenarios such as temperature detection, motion detection, obstacle avoidance, etc.diode

5. Low power consumption: Infrared sensors typically have low power consumption and are suitable for battery powered devices.

6. Anti interference: Sensors can resist external environmental interference through filtering and other means to ensure detection accuracy.diode

In short, infrared sensors have been widely used in various fields, such as smart homes, industrial production, security monitoring, etc., due to their fast response, high sensitivity, and multifunctionality.diode
