Fresnel PIR lens has two functions: 1. It is the focusing effect, that is, the pyrolysis infrared signal is refracted (reflected) on the PIR. 2. The detection area is divided into a number of bright areas and dark areas, so that the moving object entering the detection area can generate a modified pyroelectric infrared signal on the PIR in the form of temperature change.
Our PIR sensor fresnel lens is a premium optical component meticulously designed for seamless integration with PIR (passive infrared) sensors. This lens is engineered with precision to deliver exceptional performance and accuracy in detecting motion and heat signatures.
Durability and Compatibility:Constructed from robust materials that are highly resistant to wear and tear, our fresnel lens ensures a prolonged lifespan and consistent functionality. Its user-friendly installation process and compatibility with a wide array of PIR sensor models make it a versatile and practical choice for diverse applications.
Enhanced Sensitivity and Range:Featuring an advanced design and superior optics, our PIR sensor fresnel lens elevates the sensitivity and range of PIR sensors, enabling them to detect even the most subtle movements and temperature fluctuations. This advancement leads to heightened security and efficiency in monitoring and managing spaces.
Reliable Solution for Your Needs:Whether you are seeking to upgrade your current PIR sensor system or require a dependable component for a new installation, our fresnel lens is the perfect solution. Rest assured in the exceptional performance and reliability that our product provides for all your PIR sensor requirements
