In most applications, these sensors are mainly used to detect human activities in a specific area. The motion sensor is able to detect the movement of people or objects. Outdoor P assive Infrared Curtain Detector: distance from 10 m to 150 m.ĭifference between PIR Sensor and Motion Sensor.Outdoor Passive Infrared: The detection distance ranges from 10 m to 150 m.Indoor Curtain Type: The detection distance ranges from 25 cm to 20 m.Indoor Passive Infrared: Detection distances range from 25 cm to 20 m.Ref: Elpocus Range of Different PIR Sensors PIR sensors are commonly used in security alarms and automatic lighting applications. They are most often used in PIR-based motion detectors. Overview of PIR Sensors What is a PIR Sensor?Ī PIR Sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. Arduino and Raspberry Pi Projects using PIR Sensor.How does PIR work with Arduino and Raspberry Pi?.Difference between PIR Sensor and Motion Sensor.I hope this can help you understand PIRs better! In this article, I will introduce the PIR Sensor and compare the different PIR sensors that you can find at Seeed. With all these resources readily available, it has greatly helped beginners learn about the PIR sensor. Since PIR Sensors are equipped with powerful function with low-cost advantages, it has been adopted in tons of projects and is widely accepted by the open-source hardware community for projects related to Arduino and Raspberry Pi.
