Grove Zero PIR Motion Sensor

• Grove Zero PIR Motion Sensor
• Made of infrared-sensitive materials
• Detects when human or animal passing by within its detection range
• Made of a special material that is sensitive to infrared(IR) light
• Can find an object in a specified area in a range of 3-5 meters

The Grove Zero PIR Motion Sensor is the abbreviation for Passive Infrared Motion Sensor, which is made of infrared-sensitive materials. When the sensor is idle, it detects the ambient amount of IR radiated from objects in its field of view, like the room furniture or walls. When a human or animal passes by in this area, the infrared radiation intensity varies. That’s how a PIR motion sensor can find an object in a specified area in a range of 3-5 meters.
