Small PIR Lens for Smart Home Device | Sensing Angle 360° | Wall/Ceiling Mounted | 8m Detection Range

Over 30 years in Fresnel optics, Shandong Yuying Optical delivers certified high-quality optical solutions worldwide.

Human body infrared sensing Fresnel lenses are key components in infrared sensors, widely used in smart homes, temperature guns, security systems, infrared alarms, motion sensor switches, outdoor cameras, infrared thermometers, infrared imaging, and motion-activated lighting. Their primary function is to focus and regulate infrared radiation to ensure accurate detection.

How Does a PIR Fresnel Lens Work?
PIR Fresnel lenses divide infrared radiation into multiple sensing zones and focus thermal signals onto the pyroelectric sensor. When a human body moves across the detection area, the sensor detects changes in infrared energy and triggers the system.

Customized Services Yuying offers customized Fresnel lenses based on customer requirements, including different sensing angles, detection distances, sizes, and test ratios. All of our products are made using original molds, preserving the accuracy of the original design and reducing the precision loss and time delays caused by secondary mold changes. New products are typically available for sample delivery within 30 days.
