Senba F11 Square Fresnel Lens for SMD PIR Sensor (1 Piece) - 7.8x7.8mm HDPE
The Senba F11 Square Fresnel Lens is a precision optical component designed to enhance the sensitivity and detection range of SMD-type Passive Infrared (PIR) sensors, commonly used in smart home automation, security lighting, and alarm systems.
Features
- Optimized for SMD PIR sensors to increase infrared signal collection.
- Provides a 4-meter detectable distance with a 70° viewing angle.
- Constructed from durable, transparent black HDPE material.
- Compact square form factor measuring 7.8 x 7.8 x 3.6 mm.
- Easy to install directly onto compatible SMD PIR sensor modules.

This Fresnel lens is an essential optical accessory for PIR sensor modules. One side is smooth, while the other features a concentric ring pattern designed to focus and modulate infrared radiation from moving heat sources onto the sensor’s pyroelectric element. This optical surface significantly increases the sensor’s sensitivity and effective detection area.
While primarily designed for modern surface-mount device (SMD) PIR sensors, its miniaturized size also makes it suitable for use with standard DIP-type PIR sensors in space-constrained applications. The lens is a critical component for defining the final detection zone and performance characteristics of any PIR-based motion detection system.
