Grove - Adjustable PIR Motion Sensor is an easy to use Passive Infrared motion sensor, which can detect infrared object motion up to 3 meters. Any infrared object moves in its detecting range, the sensor outputs HIGH on its SIG pin. And you can adjust the SIG HIGH time up to 130s via the potentiometer, moreover, you can adjust the detection range via the other potentiometer.
What is PIR Sensor?
A passive infrared sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.
Seeed provides several PIR Motion Sensor with various range and features that will meet your different needs:

What is Grove?
No jumpers or soldering required, Grove makes it easier to connect, experiment, and simplify the prototyping process significantly. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Each one comes with clear documentation and demo code to help you get started quickly. Not only are these open hardware, but we also have open-source software.
We've Released the Grove Selection Guide and hope to help you find the Grove suit you best.
