Crumbled to the touch after about a year outside despite being made for outdoors. These start from around $5 on ebay. There are two important components for PIR-based motion detectors, one is PIR element sensor, it can convert 9-12um infrared wave to electronic signal,  it's anti-white light interference of nature, so when without human movement, PIR only detects the background temperature. Fresnel lens and conventional lens. When motion is detected the PIR Sensor outputs a high signal on its output pin. The PIR sensors are more complicated thanthe other sensors as they consists of two slots. Infrared PIR Fresnel Lenses (Pyroelectric Infrared)Willow offer a wide array of Infrared Fresnel (IR) lenses moulded in consistently thin flexible opaque plastic with the advantage of least absorption loss. The working theory: In nature, any objects that with the above absolute degree temperature (-273 degree) are emitting infrared wave, different temperature objects, emitting infrared wave length are different, so infrared length is related to the temperature. Was: £24.09. Several models are available, each creating a detection pattern with a specific range and viewing angle. 5x PIR Motion Infrared Sensor Fresnel Lens Cap Cover Shield 8308-4 UK Seller. The electronic sensor used to detect the movement of human being within a certain range of the sensor is called as PIR sensor or passive infrared sensor (approximately have an average value of 10m, but 5m to 12m is the actual detection range of the sensor). So you cannot use a cover that is translucent to IR. The other component is fresnel lens, there are two kinds of fresnel lens; refractive type and reflective types. offer a tremendous degree of flexibility, from usefully wide-angle to impressively long reach.
