What are the applications of Passive Infrared Sensors (PIR)?

What are the applications of Passive Infrared Sensors (PIR)?

Passive Infrared Sensors (PIR) are commonly used in motion detection for security systems, automatic lighting, and energy management.

How do PIR sensors work in security systems?

PIR sensors detect infrared radiation emitted by objects, like humans, and trigger alarms or notifications when motion is detected.

Can PIR sensors be used in smart homes?

Yes, PIR sensors are integral to smart home systems, enabling automated lighting, security alerts, and energy-efficient management.

What are the limitations of PIR sensors?

PIR sensors can be limited by environmental factors like temperature changes, obstacles blocking the sensor's view, and sensitivity settings.

Are there any alternatives to PIR sensors?

Yes, alternatives include ultrasonic sensors, microwave sensors, and dual-technology sensors that combine different detection methods.
