Description

The S9001 Fresnel lens is an optical component specifically engineered for Passive Infrared (PIR) sensor applications. Its concentric ring structure focuses infrared radiation from a wide field of view onto the sensor’s pyroelectric element, significantly increasing the system’s sensitivity to human motion. The smooth outer surface and precise focal length ensure optimal performance in intrusion alarms and smart home automation.

This lens is a critical accessory for any PIR-based motion detection system, converting the raw sensor into a functional module with defined detection zones. Its design offers a more compact and cost-effective solution compared to traditional bulky optical lenses, making it the standard choice for modern PIR sensor integration.

Key Features

  • Engineered for PIR sensor sensitivity enhancement and field-of-view definition.
  • Features a 120° wide viewing angle for comprehensive area monitoring.
  • Provides a consistent detection range of up to 5 meters.
  • Manufactured from transparent High-Density Polyethylene (HDPE) for durability and optical clarity.
  • Compact form factor (13.6 x 13.6 mm) with a precise 6 mm focal length for easy integration.
  • Standard design compatible with a wide array of common PIR sensor housings.
  • Optimized performance-to-cost ratio for mass-produced security and automation products.

Frequently Asked Questions

What is the primary function of this S9001 Fresnel lens?

The S9001 Fresnel lens is an optical accessory designed specifically for Passive Infrared (PIR) motion sensors. Its concentric rings focus infrared radiation from a wide 120° field of view onto the sensor's detecting element, significantly increasing its sensitivity and defining the detection zone for reliable human motion sensing in alarms and automation systems.

Is this lens compatible with all PIR sensor modules?

This lens is a standard size (13.6x13.6mm) commonly used in many commercial PIR sensor modules. For optimal performance, you should verify the mounting dimensions and focal distance requirements of your specific PIR sensor. It is designed to be a direct replacement or upgrade for lenses in many smart home and security sensor units.

How does the viewing angle and detection distance affect installation?

The 120° viewing angle provides a broad cone of detection, ideal for covering open spaces like rooms or hallways. The 5-meter range defines the maximum distance for reliable motion triggering. For best results, install the sensor-lens combination at an appropriate height (typically 2-2.5 meters) facing the area of interest, ensuring no large obstructions block the field of view.
