2-channel Motion and Direction sensing PIR sensor.

This module contains two independent PIR sensors laid out side by side in a horizontal viewing angle. This sensor offers several advantages over the cheaper and widely available single sensor versions. It can detect not just motion; the general location and movement direction can be resolved as well. This ability makes this useful for robotics applications and other projects that may require such feature.

The multiple sensor feature can also be used to reduce false alarm occurrence.

Operation Voltage: 3.3V to 5VDC
Detection Range*: >5 meters
Detection Coverage: >120 degrees along the horizontal plane
Recommended Mounting: PCB long axis in vertical position
Number of Sensors/ Outputs: 2 (Vcc Level Logic)
Sensitivity Adjustment: None
I/O Connector: 4 pin Wafer Type 2mm pitch

Important: PIR sensors require up to a minute of power ON setup time before they start to work.

*Detection distance depends on several environmental factors. Generally, distance is reduced when the ambient temperature is close to 37C, and/or under strong light.
